NintendoDS MIDI controller for SID-BOX 6581 (Filter)

Filter test for 6581
My nintendo DS is running my custom midi controller app
you can act on the graph bars modifying Control change midi events
and playing notes as a keyboard
this app is written with Devkitpro C++ tools, using Libnds libraries (for Nintendo DS)
and in CCS C (for pic+6581 module)

MIDI commands are sent from nintendo DS using DSMI libraries by WiFi and routed with Beup to SID-box with an external MIDI cable
