From the project
A (still work in progress) STM32-BluePill based MA-Style midi controller featuring 60 buttons and 15 faders.
A (still work in progress) STM32-BluePill based MA-Style midi controller featuring 60 buttons and 15 faders.
The project is made up of two PCB types. A controller PCB and a keys PCB with can be assambled both for the keys above or under the faders.
The files for the front plate will be uploaded soon.
