Sonic-Pi, OSC and Renoise

Howdy folks. I wanted to share a little project I’ve been dabbling around in for creating ambient tracks. I’m using Sonic-Pi to generate note data then sending it to a Renoise DAW via OSC. In the example below, I’m using 5 tracks in Renoise, each with a U-he Zebra2 VST attached to it. Each Zebra2 VST uses a different “program” to generate sound; pads, percussion, leads, etc. In Renoise, it is possible to record the note information in each track from Sonic-Pi for tweaking/editing later or simply forego recording the note data and record the sounds in real time to .wav format.

This is a mostly a proof of concept effort so it’s pretty simple. The first section sends set-up data to Renoise and sets a random seed. The second part contains note parameters and the OSC commands to be executed. I have to work out converting some of the other note data to a number format Renoise can handle. More to come. :slight_smile: Cheers.
