The new USB-Octomod Software GUI.

The USB-Octomod software now supports MIDI input. Using MIDI controller numbers 20 – 27, you can convert MIDI to control voltage. The new version is a free download here.

My tabulaRasa cycling through 11 different custom waveforms:

Octomod PD-Extended object, and modified NRCI library.

Hi,
I’ve made an Octomod object in PD-extended and bundled it with a modified version of the NRCI library I co-developed a few years ago. It’s got a great set of control data and rhythm generators, which make it really easy to get some interesting patterns up and running quickly – and now sent out over OSC to the Octomod Processing app.
Here’s the PD-Object and library:

(open the -workspace.pd file)
And for more info on the use of NRCI:

Check it out, and let me know what you think!

tabulaRasa

Added a page for my new project, a wavetable oscillator on an Arduino shield, called tabulaRasa.

Here’s an early demo, reading a sine waveform:

Breadboard Octomod

George Macklin wrote about his breadboard version of the Octomod here.

Here’s his (super-clean) version:

USB-Octomod Feature

The Octomod is now featured in the Projects section of PJRC.com.

Updates and Arduino Wavetable Oscillator

Here’s my finished Octomod:

The project continues:

  • Second batch of PCBs has arrived.
  • A small number of component sets has been ordered for kits and assembled boards.
  • Teensy 2.0s should be back in stock within a week.

My new project is a voltage-controlled wavetable oscillator, with SD card storage, voltage control over waveform blending, and in an Arduino shield format. I’m currently breadboarding the prototype, and really pushing the Arduino platform. It’s going to be awesome.

Arduino Modification for USB-Octomod

Spent the better part of Sunday afternoon making the USB-Octomod work with an Arduino. There is a bundle containing code and instructions linked here.
