Palm Drum Kit Studio

Ok, this is a toy application more than anything, but fun none the less. The more musical toys you have the better I say, and as it is also freeware who can argue.

Here’s the right up about it.

Play your sequence with this pretty Drum Kit Studio. Drums, Cymbals,
Hihat.. briefly drum-kit instruments you need are there. May be you
need double styluses.

The Mobile Studio: New Speakers

I ordered these speakers from Amazon a few weeks ago, and they arrived yesterday. They were a little bit bigger than I expected, but aside from that they are an excellent addition to the mobile studio.

Capers: Running the apps and more info

I have tried these apps on an OS5 device with little success. Where they worked best was when I had them working on my Palm IIIx using a Swivel Systems SG20. That was an excellent MIDI module in palm terms and worked really well with NotePad and BeatPad. The fact that it worked with the likes of hedgehog and burrito was a big bonus, but at the time I never delved deep enough into those apps.

Of course now I really want to I don’t have an Palm OS4.1 device anyway to use. So, I’ve decided to get an old Clie series palm. Why clie? Simple, the older clies (some of them anyway) have a built in MIDI chip and hence don’t need a module like the Swivel Systems SG20. If you’re interested there’s a good list of which ones have the chip at the MiniMusic site under the hardware section.

Anyway, I thought I’d put in some more information about the Capers applets / demos which I took from the cached pages of the original site. Sadly I have no images to post, but when I get a chance to get some put together I’ll post them.

Eggtimer {Demo} is a pattern-based MIDI-syncable arpeggiator with a two-dimensional control matrix for instrument parameters.

Hedgehog is a MIDI pattern sequencer. If you are familiar with the ‘matrix edit’ function of many upscale sequencers, or the ‘piano roll’ view, you’ll be right at home with Hedgehog. To make music, you simply draw on the grid: left and right is time, up and down is note. “What could be simpler?”
What makes Hedgehog so unique is its ability to sequence up to 16 MIDI controller values at every time tick along with the notes. For example, if you have a synthesizer that has filter cutoff, resonance, volume, pitch bend and LFO width controls, you can automate each one along with the note it is supposed to play. Think of the possibilities! We can’t describe the worth of such a tool in HTML. Just try it.

Hedgehog also syncs to MIDI F8 clock via Capers, and sends MIDI Sync as well, so it can play nice with your other gear.
There are math functions for pattern permutation: you can quantize a pattern to 1/8th, 1/4th or 1/2 notes, randomize the pattern or the controller sequence via various parameters, or stochastically alter the sequence while keeping either its tempo or melody. All in real time, while the sequence plays.

Capers can load any number of sequences, so you can load a group of them to play at once (or on different channels for different instruments.) Excited yet?

baby Hedgehog
baby Hedgehog is a standalone version of Hedgehog that lets you sequence 12 patterns and 2 channels per pattern. You don’t need Capers to use this version, and it is the version whose beta we are offering for free above.
From its menu system, you can set which controllers of the 16 each block refers to, the MIDI channel of the left and right side of the pattern, and the MIDI sync parameters.

Tractor Pull {Demo} is a MIDI controller LFO and control bank for controlling instrument and software parameters.

The Mobile Studio: Wrap around Applications: Spectrum Analysis


I just bought this app as another component to add to my mobile studio. I have to say it is an excellent application. Brilliantly responsive and really interesting to use. My plan is to use it to analyse the output from my work using my mobile studio to give me an idea on the range of the output. I’m looking forward to using it more in anger.

However, it is not an inexpensive application. I cost me about £20. I don’t mind as I think it is worth it to support developers who put these kind of apps together, and it helps me further build my mobile studio.

Here’s a few more of the technical details though:

The software generates real-time fading frequency spectrum or 1/3 octave ISO bar. An intelligent wave monitor window gives you a stable waveform display. Smart peaking envelopes are provided for music monitor. HandDee features makes speaker system frequency response & musical recordings check a snap.
More HandDee than standalone handheld audio RTA. (real-time analyser)

Features Highlight:

Waveform, fundamental frequency readout, plus either spectrum analyser or1/3 octave ISO bar display.
Fading reveals trends in waveform and spectrum plots.
Transition effect is even better than long persistence phosphor used in oscilloscopes.
Pause function for detailed inspection of waveform or spectrum / ISO bar display.

Other Features:

Waveform Display features

HandDee intelligent display with automatic triggering shows stable sound samples upon receiving stable sound input.
HandDee automatic scaling to expand low level sound signal for easy examination.
Digital frequency readout and marking on spectrum
HandDee fundamental frequency measurement with overtone rejection.
Loudest note display when multiple sounds detected.
Accuracy of about 0.5% or 1Hz, 10 times better than Fourier Transform.
Spectrum analyser & ISO bar Display features
Grid lines can be turned on or turned off.
HandDee musical sound peak power envelop.
1/3 octave ISO bar display.
Analyzer settings
Turn on/off grid lines.
HandDee preset analysis parameters for frequency and time averaging.
Three frequency scale selection.
15Hz-250Hz frequency range for woofer characteristic measurement.
15Hz-4KHz frequency range in monitoring musical performance or recordings.
15Hz-22Hz frequency range for all band response checking of hi-fi systems.

There’s a trial version available at palmgear. Try it out, it is fun to use.

The Mobile Studio: Wrap around Applications: ChordLab


So I’ve bought Chord Lab as part of my extended set of music apps running on my T3.

  • Features a built-in Circle of Fifths
  • Chord Finder

The Mobile Studio: New Hardware

I plan to write a full piece on my mobile studio soon enough, but in the meantime I thought I’d write something about one of the next items I’m adding. I wanted some speakers to go with my mobile studio, something small, non-powered and very versatile. I found these and have them on order from Amazon at the moment. I’ll let you know how they sound when they’ve arrived.

The Mobile Studio: Wrap around Applications: Rhythm Pro


I’ve been planning to buy this app for a while, and I am going to in the next day or so. Why? The first reason is that I think it is important to support developers who make music making apps for the palm platform. Secondly, I like drum machines, and a stand alone drum machine app for palm is a fun idea.

Capers: Source code coming soon

The source code is still on the way. If anyone is interested in doing anything with it, please let me know I’d love to track the project(s) relating to this.

Libretto Reborn!

Well, finally I’ve got ReBirth running on my Libretto 70CT. The downside is that it has to run with a CD-ROM, but there’s a way around that.

I think the Libretto is now going to be a useful part of my mobile studio now, which I’m glad about as I won’t have to sell it!

Letter published in Computer Music

I wrote a letter to Computer Music magazine a few weeks back and they’ve published it!

The letter is all about handheld music, and specifically Bhajis Loops. Whilst it didn’t get letter of the month it is the next one on the letters page entitled “Polyphonic Pockets” and even has a photo of a Zire 72 running Bhajis (taken from the Chocopoolp site I imagine).

The editor says at the end of the letter that they’re going to run a feature on handheld music in the future. I plan to contact him about it to offer help / links etc.

If I get any more information about a feature I’ll share that too.
