MIDI retrofit for CR-78 Part 5
YouTube via MusicMiK. follow-up to this post
"A bit tired on the first day of 2010, but enough to do some cleanup in the source tree and implement basic CR-78 hardware interfacing.
The hardware works as desired, the rest of this is just tricky firmware to have all the desired features enabled. Sync/Start/Stop still needs a bit improvement, but the way the machine works in detail is now analyzed and can be handled.
Currently implemented:
MIDI sync in and out
Triggers to/from MIDI, currently with not special handling for the Accent-trigger, which will be mapped to velocity later.
Still some things to change in the main logic to compensate some hardware strangeness of the CR-78 like the VCAs being shut down when the unit is stopped, so it always needs to run to get the triggers from MIDI routed to the hardware.
The handling of the switch between internal and MIDI control can also be improved using the start/stop button to switch off pure MIDI control and return to native machine clock.
Usual disclaimer: I will not build and sell kits and i will not implement your firmware wishes. This is your job, when the finished version of schematics/source go to http://www.mik-music.org/MIDItriggs"
