I received a 301 a couple days ago and of course I’m in complete awe. Barely beginning to scratch the surface but here’s my first attempt at a custom unit — scannable harmonic oscillator inspired by a well known Eurorack harmonic oscillator, built around Sine Oscs and the brilliant Bump Scanner unit. Controls should be pretty self explanatory — ‘center’ scans through harmonics, ‘bwidth’ sets the width of each frequency band (bands have to overlap for smooth scanning), ‘xfade’ controls Bump Scanner’s ‘fade’ parameter, ‘fdbk’ controls Sine Oscs ‘feedback’ parameter and individual harmonics level faders control… well, individual harmonics levels.
Processor load should be around 33%.
Thanks Neil Parfitt and Joe Filbrun for your incredible videos!

- added FM (via ‘fm in’ local control — assign audio rate signal!)
- added FM amount (exponential envelope from Maths works great)
- small fixes
