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: 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: Anyone interested in taking the code further?

The next step with the capers project is to find someone to take on the code and take it further. Any takers out there?

Run PC apps on a Palm?

Does this mean that I could run Rebirth on my Palm T3 alongside Bhajis Loops? Who know, we’ll have to wait and see what pans out with the beta version if it appears.

Capers: Code to be released SOON!!!

I’ve just got an email from the developer of the code for capers. He says he is planning on releasing all the source for hedgehog / eggtimer /capers libs sometime soon.

As soon as I know more I’ll post on this again.

Capers: Making the applets and demos available.

Thanks to fluxivity for comments. I really glad you like the blog. Please spread the word.

In terms of getting hold of these applets, you can’t download them anymore as the site has gone. However, google holds cached versions if you search for stuff like “hedgehog capers”. I am going to try and make the files available somewhere, I just need to work out where to host them. I don’t think there should be any issues about making them available as they were freely downloadable before. I will make sure I post a location as soon as I’ve got it sorted.

BTW I have also contacted the original developer about the source for capers but so far have had no response. If I do get a response I will post on it.


In my last post I mentioned ChordLab. The more I look at it the more I think that it might be quite useful. Here’s what the developer says about it.

The essential tool for song-writers and musicians in general assists with all chord spelling tasks. Features a built-in Circle of Fifths and chord finder for when you know the pitches, but not the chord. Many times chord spelling becomes an essential task, be it to communicate what you are playing to others or simply when writing it down. To complicate matters music theory is often complex and correctly spelling a chord that may have sharps AND flats, double flats or double sharps is not always easy. That is where ChordLab can be of great assistance as a sort of chord calculator.
In addition ChordLab can also show you how to finger given chords on the piano or guitar. It features all the standard voicings commonly used in Jazz, Rock, Pop, and elsewhere. This helps to write fitting music for an instrument one might not be too familiar with.

Another essential tool found in ChordLab is the Circle of Fifths which is implemented interactively and can be used to show parallel minor/major key signatures.

The most important tool for many, however, will probably be the Chord Finder. This tool allows one to just enter a bunch of notes and find out what chord exactly these might represent. Many guitar players often play fingering combinations without being aware of the kind of chord these notes might represent. Notes can be entered just by pitch and without having to have the correct name.

Mozart 3.0

I got an email telling me that Mozart had been updated. Ages ago I bought this program as part of their bundle, but I have to admit that I hardly ever used it. The new design looks good, but again I wonder if I would use it.

Their other app Chord Lab looks like it would come in handy though. Perhaps I’ll do a post on that.

Anyway, here’s what they say about the new version of Mozart 3.0,

Mozart 3.0 adds a multitude of new features. The application has been completely redesigned and addresses many requests. Most importantly the application now uses a new kind of sound library that offers very realistic sounding instruments. The use of these libraries will over time also become a part of Almond and ChordLab. A new addition is the use of key signatures and ranges. Sessions can now be replayed and instrument interfaces have been redesigned and are more spacious than
before. A bass instrument has been added and the instruments bass, piano and guitar can hilite notes and locations of the key being used. Music Bundle and Music Bundle Pro have been updated as well to include this new version of Mozart.

Found: Capers Demos and Applet betas

I thought I had these somewhere, but couldn’t be sure. Now I have them. This is what I’ve found:

  • Hedgehog
  • Egg timer
  • Meedy
  • Burrito
  • Tractor

My recollection is that they don’t work on an OS5 palm. However, my plan is to try and run them on StyleTap and see how that works out.


I remember seeing info about Capers way back when I started to look into making music on a Palm device. I thought it was just the coolest idea. A whole replacement OS for the palm that was only about music. What happened to it? I don’t know. I expect like a lot of really cool ideas it got lost along the way.

All I could find on Capers was the following:

Capers runs on the PalmOS and all compatible devices (Palm Pilots, IBM Workpads, Handspring Visors) are able to use it. The intended goal of Capers is to create a “replacement music operating system” for the Palm, in effect generating a handheld music platform rather than a group of applications.

Capers uses a common clock for all its “applets,” and the user can page through them at will while a sequence plays. There can be multiple instances of each applet; for example, three arpeggios, two sequences, and four controller LFOs can be used at once. Each applet’s output (called a “Pattern”) can be sequenced to create a song of a group of “patterns.” This sequence can sync in or out to MIDI clock to talk to other sequencers such as Native Instrument’s Reaktor, Akai’s MPC series, Ross Bencina’s Audiomulch, or even another Palm OS device running Capers!

Capers is in alpha testing and we will be offering it with the dsperado hardware shortly. (You don’t need the dsperado hardware, however, it works just as well with standard MIDI equipment.) To tide you over, we are offering demo and beta versions of three of the core Capers applets (whose full versions will also be available separately if you don’t need all of Capers.) These versions do not contain all of the functionality inherent in the full release versions, and may contain bugs. We hope you enjoy them, and please get in touch with any feature suggestions or problem reports.

API – Programming:
We also offer Capers as object code for developers who wish to create MIDI-enabled applets. Simply link the Capers object into your code and you can have access to a stable high-resolution timing clock, a MIDI input state machine for controllers, notes and Sysex data, and F8 Sync in and out. You can develop for the Capers master sequencer or create your own standalone applications.

Capers Applets and Downloadable Demos:
Eggtimer {Demo} is a pattern-based MIDI-syncable arpeggiator with a two-dimensional control matrix for instrument parameters.

Baby Hedgehog {Beta} is a pattern sequencer that also sequences 16 MIDI controller values. The beta version stores 12 patterns and allows for various math-based functions for random pattern generation.
Tractor Pull {Demo} is a MIDI controller LFO and control bank for controlling instrument and software parameters.

Coming soon:

  • Blueberry – MIDI Patch / Sysex Librarian and Sound Randomizer
  • Cardinal – dsperado Hardware Front End / Librarian
  • Carpetbomb – Xenakis emulation

There’s not much else, but what there is you can find by searching for Capers Dsperado.

It would be wonderful if it could be brought back to life, but I doubt that will happen. Anyway, good to remember it if nothing else.
