a 32 / 72 channel MIDI controller for
the mixing console
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.

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.
