A simple 16 step CV sequencer built around a Korg Nanokontrol
This project consist of a new firmware and hardware modifications to turn a Nanokontrol into a CV sequencer. It serves as an example of how to interface the potentiometers, buttons and LEDs of the Nanokontrol.
To apply the firmware and modifications, a few steps shold be followed.
- Create an SPI adapter as per the schematic
- Flash the fuses with "-U lfuse:w:0x3f:m -U hfuse:w:0xd0:m"
- Desolder the PDIUSBD12 chip
- Jumper the crystal to the Atmega32
- Wire in the MAX528
- Flash the new firmware
