From the project
Desktop Development Kit for the Daisy Seed
- Added missing diode to MIDI input circuit
- Removed components from audio input circuit that introduced noise: R64, R65, D21, D22, D23, D24 - Connected switching connection on CV Input jacks to GND to prevent idling at non-0V - Added silk screen indications for software mapping to Daisy for all pins/peripheral information. - Swapped CV out 1 and 2 from the seed so that the software channel matches the hardware label
