[sdiy] My new 6 voices MIDI interface..

[Jean-Pierre Desrochers]

Hi list,

I've just finished my third dotcom type module..
It's a 6 voices MIDI interface with arpeggio
and polyphonic portamento. Note that the arpeggio notes
are ALLWAYS sorted in their musical scale order and not
their played order.. more musical !
I've used 12bits precision MAXIM DAC's for stability
and Analog Devices digital pots for portamento.
All note CV's are 1v/oct (0-10v range) with their
respective Gate outputs.

All my files and specs are located here:

The module specifications:

Construction and assembly using auto adhesive, laminated vinyl
for front panel layout placed on front aluminium plate and a table press punch for all holes:

Feel free to ask any questions.
This project took me around 18 months to finalize.

Thanks for watching.
