Would it be possible to modify this project to add either another DIN or DOUT in order to achieve a 24 X 16 scan matrix? I am working on a 192 key velocity sensitive keyboard (axis-64 clone). Is it just a matter of changing these: // scan 16 rows #define MATRIX_NUM_ROWS 16 // maximum number of supported keys (rowsxcolumns = 16*16) #define KEYBOARD_NUM_PINS (16*16) Thanks, Tim

I am working on making a copy of the axis-64. It is based on cherry MX switches, I am using a different method to achieve the velocity sensing. See the attached diagram: So far I have used din_velocity_unmuxed_v1c.zip for software and have achieved good results, but this project is limited to 64 keys. I have seen the fast scan project for the 32 bit core, but even that project is limited to 128 keys. Does anyone have ideas for achieving 192 keys (384 inputs) or is this not feasible for a single core?

Does anyone know if the Bourns PSM Series Motorized Slide Potentiometers can be used for midibox LC? Details here: http://www.bourns.com/data/global/pdfs/psm.pdf
