Cabbagenic uses only Cabbage instruments converted to native Linux VST plugins. One Cabbage effect - the multiVerb - is used for a global reverb, but a single instrument - FMClang - uses MVerb, an open-source reverb by Martin Gardner. MVerb is the only non-Cabbage plugin used.
The first section was made with the Rubbed Resonators, Bar Model Synth, and Wavetable Synth instruments. The second section was made with Honk, FMClang, and the String Feedback Synth. The final section was made with the Harmonics, Bass Guitar, and Inharmonic Additive Synth instruments. The last part recalls the instruments from the first section in a single sustained chord.
Btw, all of the sounds are from the plugin presets. I made few changes to the original preset designs, typically only to set a more amenable output level. I had a lot of fun using these instruments, but the real sound programming was done by Iain McCurdy.
Cabbagenic was sequenced and rendered with Bitwig Studio for Linux.
Thanks for your interest, I hope that tells you a little more about how Cabbagenic happened.
