a 32 / 72 channel MIDI controller for the mixing console
 
DIY MIDI Controller with mixing function

32 rotary encoders are included in the box. A Xilinx FPGA is used to interpret the movement information and send it over 460kbaud serial interface to the computer or the DIY audio workstation. The controller data is 10 bits with 1024 step resolution using intelligent acceleration. The FPGA is also used to control the data streams. See an older version of my MIDI Controller for more details.


 If desired the transmission speed could be increased up to 920kbaud, but 460k is the limit of my PC's UART interface. The data format follows my improved MIDI 2000.

Setup for Equalizer Controller Option:

A next step is to enhance the controller by more channels to achieve 72 channels and implement the MIDI over S/PDIF for fast transmission and adaption to the workstation.
