Crumar GDS MIDI interface testing


Published on Jul 30, 2015 Michael Kukat

First part here.

"Another video about the Crumar GDS MIDI interface.

This time, both interfaces are in use. One is running in master mode, sort of emulating a real GDS (just the scan processor, not the synth), the other one in slave mode, working as a GDS MIDI interface.

The purpose was to test if everything works as intended, as it already did on the breadboad.

Controlling the Korg Gadget on the iPad with a Crumar GDS keyboard - fun :)

In the second part, i try to describe a bit how the interface between the GDS main unit and the keyboard works and how i hook into this communication to implement the interface. The DK Synergy works exactly the same way, it even has nearly the same pinout, just number of keys and pots differ. My interface board could also be used in a DK Synergy."
