Thread: Box of Noise
+1 for bigger rack.
+1 for O_c (I suggest using alt firmware "Hemispheres").
This next bit may seem contradictory with my + for O_c, but I recommend you get a simple oscillator. Plaits is great, as was its predecessor Braids, but they are not the most intuitive modules. When you are learning modular, it is very nice to have easy access to raw wave forms (preferably simultaneously). Consider Befaco Even VCO.
Finally, this rack would benefit from a simple modulation source (Sin Phi Miasma / Rampage / Maths / Batumi).
