Music in the Palm of Your Hand

Dec 1, 2001 12:00 PM, By Cat Taylor

As a child, I loved gadgets: secret decoder rings, bat utility belts, all those sorts of things. So it figures that, as an adult, I have become a Palm addict. Desktop computers simply aren't enough; I need a cool small device that fits in a purse or a pocket and does an amazing array of gadgety things. As you might expect, many people share my addiction.

Although many people know about the Palm handheld computer's prowess at storing and organizing phone numbers and appointments, they might be surprised by the variety of music-related hardware and software products for the Palm OS platform. I will discuss some of the most interesting products, but for readers unfamiliar with the Palm computer, here's a brief introduction.

GETTING STARTED

Those who haven't used a Palm Personal Digital Assistant (PDA) need to know a few basics. You enter information into the Palm by writing and tapping on the screen with a stylus -- also called a pen -- using Graffiti, the Palm's slightly awkward alphabetical entry system. You install software and synchronize files between the Palm and a PC or a Mac by placing the Palm into a cradle that mates with its bottom-mounted serial port. A cable connects the cradle to the Mac or PC serial or USB port. The software that controls the synchronization process is called the HotSync Manager.

The Palm is a handy little contraption, but what can it offer musicians — especially considering that the Palm lacks a true speaker or amplifier? (Its rudimentary sound output is produced by a piezoelectric element.) Even when the software lets you reformat WAV files as Palm database (PDB) files, the speaker reproduces sounds inadequately. The Palm OS processes MIDI data, but only Format 0 Standard MIDI Files (SMFs) are supported, so you can't edit tracks separately.

None of those facts deter programmers, who continue to develop music-related programs at an amazing rate — I soon realized that I couldn't review all of the products on the market. I therefore focused on hardware and software that is compatible with the Palm III series of handheld devices and intended for real musical applications, as opposed to the many tools that let you catalog MP3 files, record thoughts using outside hardware, or play movies.

Many programs not intended strictly for musicians can prove to be valuable as well. For example, some programs let you convert Microsoft Word documents and PDF files into miniature versions that can be synced to the Palm. The files can include everything from documents about basic scale forms to orchestration databases created for TealPoint Software's TealInfo database program. Once you own a reader program, you can download a lot of free material from Web sites such as Memoware.com, which boasts more than 8,500 titles in various Palm formats. I wrote much of my initial research for this article using the Palm Portable Keyboard and DataViz Documents to Go.

TEACHING TOOLS

I'll start with some relatively simple programs, such as Sam Trenholme's freeware Ear Trainer. The program plays a random interval; you guess the interval, and it tells you if you're correct. That's all there is to it.

Wilson Cheng's MusicEar is a suite of ear-training programs that includes modules for learning intervals, chords, scales, rhythms, and melodies at increasing levels of difficulty. Once I figured out how to answer the questions, it was fun and challenging. MusicEar could be a great tool for music students and practicing musicians who want to brush up on their skills.

Mike McCollister's McChords lets you select more than 70 chord or scale names that are then illustrated on a keyboard and played back. It's helpful for understanding what an Am6(9) chord or what a pentatonic minor scale sounds like.

Programs designed to help guitarists determine chord fingerings are also available, but I had to draw the line somewhere.

KEEPING TIME

The Palm OS uses a 10 ms clock, and the timing of programs using an incompatible scheme could be uneven. Unless a program has a checkbox for “ignore system information” or something similar, it's possible that the timing can be thrown off by hacks, such as the one for the Palm keyboard that lets you type text into the Palm. Hacks are small programs that allow changes within the basic Palm system to enable everything from fancier interfaces, such as Synergy Solutions' Launch 'Em, to fun things, like Star Trek sounds. Managed by programs such as DaggerWare's HackMaster, hacks can be turned on and off. If you're having problems with irregular rhythms, especially with a program as labor intensive as miniMusic's BeatPad, try disabling your hacks.

Responsive Software's Responsive Metronome is a good basic metronome that uses visual cues (a note moves from side to side) or sound to provide a basic tempo. A slider along the left adjusts the tempo.

TS Tempo (included with notation program TS Noter), from Italian developer TobelStudio, is another decent metronome that features an old-fashioned wand moving from side to side. It includes a bpm setting and lets you choose sound and visual cues.

Eric Cheng's Metronome comes with PocketSynth. It also offers a bpm feature with a dot that beats on the left for downbeats and on the right for subsequent beats. If you tap the Scroll Up button repeatedly, the program measures the tempo you're tapping.

Gary Duke's Pocket Beat has an animated character sitting at a drum set. You can set up two tempos (each with a shuffle option) and switch quickly between them. When you hit the Go button, a little spot flashes on the kick and snare drums as the corresponding synthesized sound plays. You can also tap a count off to set the tempo. Although the program developers claim that it's the most accurate Palm metronome, the squeaky sound and size of the program (you must install PocketC) are drawbacks.

Calvin Gaisford's Musician Tools is a suite of nifty programs that includes a tuner, a metronome, and a circle-of-fifths program. The tuner lets you choose the base frequency, so you can tune to A-442 if you want. You can control the length of time that the note plays, and you can choose other pitches. The circle-of-fifths program lets you go around a circle of notes, and as you tap each one, it shows you the sharps or flats for that key. Musician Tools' metronome is the best of the bunch. The downbeat sounds a pitch different from the other beats, and a segmented vertical indicator shows the current beat, which helps if you want to turn the sound off. Moreover, you can choose meters with as many as eight beats to a measure.

TECH TOOLS

The Palm can serve as a valuable portable reference resource to help solve studio-related problems, wade through technical jargon, and make calculations. Palmetto Logic's Sound Advice, the most complete product in this category, rolls those capabilities into a single three-part package.

In Sound Advice's Q&A View section, a question field at the top lets you choose a general question, such as “How do I avoid feedback?” The program then offers a list of related topics, such as “feedback, notch filter,” and provides specific information about them. Choosing All in the question field shows all the topics, and you can bookmark single entries for later reference. When you click on a topic, it puts you in Advice view; from there, the forward and back arrows take you to related subjects. Clicking on the Note button creates a dated attached note that you can beam to other Sound Advice users with the Palm's infrared port.

The terminology section contains an alphabetical list of more than 200 terms. You can access terms by scrolling down the entire list or by tapping in the Index pop-up box to jump to a letter; selecting a term displays its definition. The Reference Charts section includes a chart for combined speaker impedance, recommended cable lengths, common value multipliers, and musical-scale frequencies. It also provides two calculators, Volt/Ohm/Amp/Watt and RMS/Avg/Peak, that allow you to make calculations relating to current and voltage, current and resistance, voltage and resistance, and power and voltage.

Sound Advice demands a lot of room for a Palm program — 186 KB — but it has quite a bit to offer. At $7.95, it's a great deal.

KNOW THE PLAYERS

Palm Tracker, from German developer Emperor Studios, is a tricky program that seems to play three music tracks at once by slightly delaying each track relative to the previous one (see Fig. 5). You create patterns using a small keyboard on the Patterns page and then arrange the patterns on the Song Editor page. Its rather simple note-entry capability only allows for short note values that are combined to sound like longer ones. You can't really change the basic 4/4 meter and feel, and the songs are not MIDI compatible.

Although you hear the songs through the Palm's speaker, they sound kind of cool. Palm Tracker has been used by game developers to create music for games such as Archon from Free Fall Associates. The full version lets you save files that you can export to your desktop computer and share with other users, although you can't open the files with desktop applications.

MiniMusic BeatPad is a pattern-based sequencer that allows you to create a repeating pattern of melody notes (and drum patterns if you're using MIDI). It allows you to make changes as the pattern plays and provides interactive and graphical control over pattern parameters, including the pitch, duration, and volume of each note as well as the pattern's length and tempo.

BeatPad provides two main Views: Melodic and Drum. Across the top of the Melodic View window are the controls for the 32 patterns you can create and use. Below that, the Pattern Overview acts as a viewer for the pattern creation process. Four tabs let you choose and edit pitch, duration, Velocity, and master, the last of which controls the master settings that don't change when you switch patterns, such as the tempo and the MIDI instrument patches chosen for the melodic and drum lines.

You can switch to the Drum View as a sequence plays by tapping on a button in the lower left of the screen. Because the Palm cannot deal with multiple sounds, drum sounds are audible only when using a MIDI interface. The drum screen shows the percussion sounds, lets you solo or mute them, and allows you to set up rhythm patterns. You can also set up accents or loops and enable MIDI Clock in the Preferences window.

MiniMusic solved the timing issue by using a special internal clock that looks for the nearest system clock during playback. That seems to work well — BeatPad is a fun metronome. Included with NotePad in miniMusic's Mobile Software Pack, BeatPad also comes with Swivel Systems' SG20 sound module.

MobileSoft-Labs M.Play has an attractive 3-D interface that includes basic tape-deck controls for playing single-line MIDI files. The software lets you pick tunes from a library of prerecorded songs or create your own. Although M.Play is free, M.PlayEdit costs $10. With M.PlayEdit, you can create Palm-compatible files from MIDI files and transfer them from your Windows-based desktop computer to the Palm. A demo version is included with M.Play. I created a MIDI file of one of my fiddle tunes with ease.

Tom Zerucha's free PlayMIDI is available in two versions. With the older version, PlayMIDI45A, I could play the files that came with the program, but I couldn't figure out the instructions for converting regular MIDI files to files PlayMIDI could read. The color was also odd, because the program wasn't created for a color Palm.

The new version of PlayMIDI is part of a suite of programs called ZboxZ that includes compression utilities, fax software, and other small programs. Unfortunately, ZboxZ lacks a real installer, so you must go through a rather arcane set of steps to install the software. In the new version, the files will not play without an external MIDI device, but you can actually hear the sounds as they were intended rather than be limited by the Palm's speaker. I still had problems creating files that would port properly to the Palm (probably because I use the relatively new HotSync Manager 4.0), and I had to manually rename some files before PlayMIDI would play them correctly.

If you use PlayMIDI, you will need plenty of memory: the program uses compressed files, and insufficient memory can cause a crash that requires a hard reset. I finally made the program work properly, and it should be able to play a variety of MIDI files as well as just music files. PlayMIDI is apparently the only program that lets you create multiline MIDI files on your desktop and port them to the Palm with an included utility applet.

If you're a fan of the theremin, you'll love Theremini from Pete Moss; it lets you create the effect of a theremin on your Palm handheld device. If you don't have a MIDI interface, use the Palm's internal speaker and make all sorts of weird and cool sounds by moving the stylus across the screen. The x-axis controls pitch; the y-axis controls volume. The left and right fields determine the frequency range (from 1 to 20,000 Hz); either field can be higher or lower than the other.

If you have a Palm MIDI adapter, you can use the program to send out MIDI data through a MIDI interface. I used Theremini to play sounds directly from the Swivel Systems SG20 and ran the output into my computer, which opened up a new world of sounds.

KEEPING SCORE

Among notation products for the Palm, Eric Cheng's simple PocketSynth is probably the oldest in common use. You enter notes by tapping a note value on a palette (a Rest button is also provided) and then tapping a key on the four-octave keyboard. The notes play back and show up as text values on a line at the bottom of the page. A note is represented by a symbol such as “c02,” which plays the note C in the bottom octave with a quarter-note value. Because the note information is just text, it can be entered or edited with a text editor such as Palm's MemoPad.

A slider sets the tempo, but the time and key signatures cannot be specified. You can export the notation information to Arkkra Enterprises' Mup desktop-music typesetting program using an intermediary Palm freeware program called ToMup from RMIT University. ToMup can combine as many as four melody lines and lets you enter time and key signatures, chords, lyrics, and other musical information. You can then export the files to Mup and print the music or export it as a MIDI file.

The two Palm software titles most like those common on regular computers are NotePad and TobelStudio's TS Noter. The programs let you store songs and work with one at a time, and they offer keyboard and staff entry. They also allow playback as the notes are entered or afterward through the Palm speaker or through MIDI to an external device.

Although less well known than NotePad, TS Noter has features that make it just as valuable as its competitor. It's an intuitive and straightforward program with a variety of useful features. In TS Noter's Edit View (similar to Score mode in NotePad), you enter notes on a two-staff score by selecting a note value from a palette. The palette includes values from a whole note to a 64th note and also provides triplets, rests, flats, sharps, natural signs, and an Eraser tool. Once a note is entered, you can select one of the note values and tap on the note head to change it. You can drag the note up or down to change the pitch, and you can tie or slur notes together. Bar lines are entered in the same way: by tapping on an icon and then placing the bar line in the score. Although you can't specify a time signature, you can set the tempo in the metronome screen.

Additionally, the palette includes an arrow that allows you to insert numbered markers. You can later access those reference points with the Go To tool. Items in the File menu let you beam songs to another Palm and export files as alarms to be used in other applications. (Alarms are audio or visual alerts that you can set to occur at specific times within other programs.)

The Edit menu provides the usual cut and paste functions and allows as many as ten undo levels. You can transpose all or part of a song up or down by as much as an octave. A toolbar across the top of the window offers quick access to the tempo setting (using the metronome); playback, MIDI, and recording preferences; Play and Stop buttons; the Score view; and the List view. The Piano view has the same basic menus and toolbar and permits real-time recording of a melody on a keyboard. You can scroll to view and play almost four octaves. In the MIDI Preferences screen, you can choose the Palm's speaker or a MIDI interface for output. If you select General MIDI (GM), the program provides a list of patch names.

You can send files to your desktop computer with the optional PalMusic Desktop application for Windows. Just open PalMusic, hit the Start button, put the Palm in its cradle, select Send to Desktop from the File menu, and then select Transmit. A dialog box asks where you want to save your MIDI file.

The Score View screen in NotePad looks similar to the one in TS Noter, with two staves for entering notation. With NotePad, however, you can enter as many as four voices, one a time; select them by tapping in the numbered box in the upper-right corner of the screen. You can even build chords within each voice. In the Voice Preferences screen, you can choose a voice's track, its MIDI channel, and an instrument (viewable by patch number, not GM name). Once back in the Score View screen, the Graffiti letter V toggles between “show four voices” and “show current voice.” You can also change voices by simply writing the number of the new voice in the Graffiti area.

Along the top of the screen, you can choose note and rest values ranging from a whole note to a 16th note. Enter notes by selecting a note value and placing it in the score. The note doesn't appear until you lift the stylus; however, you can hear where the note is as you move it around on the score. Unfortunately, once you lift the stylus, you can't use it to move a note, though a note can be moved by selecting it and using the Palm's Up-Down arrow button. You can also step-enter notes from a MIDI keyboard and shorten or lengthen a note in increments by drawing forward or backward strokes in the Graffiti area. Items in the Edit menu let you invert and reverse (retrograde) selected passages and convert notes to triplets. You can clear notes by selecting them and drawing an X in the Graffiti area.

Using the Song Preference box, you can select the category, key, meter (3/4, 4/4, 5/8, and 7/8), “play on entry,” “show four voices,” MIDI, and tempo. The time signature constrains how notes are entered, and placing a new note between existing notes might push them over to another measure to preserve the meter. Play, Back, and Forward buttons are at the bottom of the screen along with icons to take you to the Piano and Grid views. The Piano view includes a condensed score at the top, so neither accidentals nor a written key signature appear. You can't enter notes directly on that condensed staff, but you can select notes from the palette and play them into the score from the piano keyboard. Switching to the Grid view displays a window much like a piano roll, with a keyboard along the left side as reference. You can still edit and play back the music in this view, and Grid view also lets you draw each voice in a different color.

One of the fun things about NotePad is that it includes 19 pieces of precomposed music that you can play back one line at a time using the Palm speaker, or you can play all the lines at once using an external MIDI device. NotePad is also part of the miniMusic Mobile Software Pack along with BeatPad, Theremini, and the Palm-to-MIDI interface. You save files to your desktop computer through a conduit added into the Palm Desktop software. NotePad also lets you beam songs to other Palm users.

Neither TS Noter nor NotePad imports MIDI files, though both export files that you can adapt with another program to replace Palm system alarms. But that's another hack.

PACKIN' HARDWARE

MiniMusic's Mobile Software pack includes the Palm-to-MIDI interface. To set it up, connect a serial cable, cradle, or travel adapter to the serial port at the bottom of the Palm and connect the other end to the Palm-to-MIDI interface. A MIDI cable connects the interface to your computer or the MIDI In port of a MIDI device. You then open a MIDI-compatible program on the Palm, make sure MIDI is turned on, and hit Play. I hooked up the Palm-to-MIDI interface to the MIDI In port on my PC and played through Voyetra's MIDI Orchestrator Plus with no problem.

The Swivel Systems SG20 is a small battery-powered tone module that clips onto the Palm's base at the serial port. As wide and deep as the Palm, the SG20 measures less than 2.5 inches in length. The SG20 has two output ports: one for headphones and one for an RJ11 cable. You can play MIDI applications and listen through the headphone jack, but that's just the beginning. When you plug the provided RJ11 cable in to its port, you can connect a small device that has MIDI In and Out ports, a MIDI-activity indicator light, and two RCA output jacks. In my tests, both units worked admirably.

The SG20 boasts a complete GM sound set and all the polyphony and features needed to make it fully GM1 compatible. Its onboard sounds and versatile design make it suitable for serious Palm-based composition. Other small battery-powered tone modules, such as the Yamaha MU15 and Roland PMA-5, attach to the Palm through the serial port, but unlike the SG20, they weren't created specifically for the Palm.

Handi-Q's HandiClip is an ambitious hardware and software system for remotely controlling high-end effects, mixers, and equalizers from the comfort of the Palm. According to Handi-Q's Web site, the system works with several devices, including the TC Electronic TC 1128, M2000, M3000, M5000, M-One, and D-Two; the Ashly Protea and VCM-88; the Behringer Ultra-Curve; the Yamaha O1V, O3D, SPX 990, and ProR3; the Lexicon PCM 70, PCM 80, PCM 90, and MPX 1; various MIDI synths and drum machines; and some intelligent lighting-control consoles.

The HandiClip attachment looks much like the SG20 (a standard shape for external Palm modems as well), except that it has a light that blinks red or green to show MIDI activity. It comes with an RJ11-to-KLR A3M adapter cable and an XLR-to-MIDI Y-cable. The RJ11 (telephone) cable plugs in to the port on the bottom of the HandiClip and attaches to the XLR-to-MIDI Y-cable. You can then plug the MIDI connectors in to the unit you wish to control. I plugged the setup into my PC, and it functioned the same as the Palm-to-MIDI interface and the SG20. The adapters let you plug the HandiClip in to longer RJ11 cables or in to a snake for controlling your units from a distance. The XLR cable can be used with the Protea using the RS232 or MIDI protocol.

Handi-Q has also just released its new HotSync-to-MIDI cable, which costs considerably less than the HandiClip. It offers a direct connection from the Palm serial port to a MIDI-controllable device through a MIDI Y-cable. Green and red LEDs on the MIDI connectors indicate data presence; simultaneous in and out flow is supported. Because the interface lacks batteries, it drains the Palm's batteries quicker than the HandiClip does.

According to the documentation, the HotSync cable performs successfully when connected through XLR cables on a snake cable run of 750 feet, but for anything longer than 600 feet, Handi-Q recommends the HandiClip. The HotSync cable also lacks the HandiClip's protection for the Palm from “improper cabling mishaps.” In my tests, the interface worked just fine, but unlike most of the other cables, the ends are female, so you need regular MIDI cables to connect it to your equipment.

IN CONTROL

To use the Handi-Q products, choose the apparatus you wish to control and then download the appropriate Handi Systems Controller Software. Within the software, select a MIDI channel for each device that you want to control and adjust the parameters using faders. In the EQ software, you can set the faders in real time. You can also run in unsynchronized mode in case the EQ settings on the unit get changed while you are away from it. Then, hit the Synchronize button to send the information to the unit. In Handi-Q Ultra-Curve, the software's EQ curve is added to or subtracted from curves already in place on the EQ device. The documentation for the HandiMix VCA control software states that you can use the program with any equipment that has insert capability.

Because I use effects devices with my electric violin, I tried HandiFX. It lets you choose and name the mechanism you wish to control, set the MIDI channel, assign the controller number, and specify the minimum, maximum, and default settings. You then switch to the main screen to operate the faders attached to the selected device. You can save the settings to a Palm Memo file for retrieval later and back them up to your desktop computer when the Palm is synced. I tried that with an MPX 500 from Lexicon, and it worked great. It won't send Program Change messages, but that capability is coming in a free update. Although the programs can be downloaded from the Handi-Q Web site, they only send out MIDI data after you enter the HandiKey (available after you pay for and register the product).

MiniMidi, from J. T. Solutions, simply sends messages to MIDI devices; it's more basic and less expensive than the Handi-Q products. MiniMidi's first screen is the Main/Keyboard page, which has a keyboard at the top to test the selected MIDI channel settings. A small horizontal slider lets you choose the MIDI instrument for the selected channels in the line of boxes below. The vertical faders just below send continuous controller messages to the controller, which you choose from a pull-down menu that includes three presets and four user settings. You can save settings on four pages. All the settings can then be sent at once, on the appropriate MIDI channels, to a number of MIDI-controllable devices. The program also lets you send different controller data on the same MIDI channel. You can set the controller number and the name for each field in the setup screen. As with the previous section, four banks of settings can be sent simultaneously. I tested MiniMidi on my PC, and it worked fine.

Geoff Smith's MidiMonitor lets you monitor incoming MIDI messages using a number of configurable fields. Data can be received in hex format, in decimal format, or as raw MIDI data. I tested MidiMonitor with the volume and wah pedals on a Line 6 Floorboard sending messages in to a Pod Pro and out the back as MIDI data. Although the program displayed continuous controller MIDI data, it did not seem to be consistently accurate. That was also the case with MIDI data from my PC. MidiMonitor may eventually be very cool, but at the moment, it's somewhat unreliable.
