Thread: First Idea
Check out VCV Rack and a few Omri Cohen YouTube tutorials to get familiar with the concepts of modular synthesis
Then get a bigger case with more power than you think you'll need
A minimal starter setup would be Keystep (or Beatstep) + Plaits (or Chord) + some way to hear the sound (like a mixer or ALM HPO)
Keystep CV and Gate outs will go to control Plaits V/OCT and TRIG. Plaits OUT to mixer or headphone amp.
Next steps should be modules that can do more with this setup. Pam's New Workout or Maths would be great to add modulation to Plaits parameters
