The `mod' files (mod1-5, gif and ps.Z) are schematics of my MIDI to Trigger converter. Designed for use with the Roland CR8000 drum machine, they should work with any other drum machine using negative-going pulses (that's a 5v to 0v pulse) - possibly even an 808 (if anyone wants to give me an 808 to experiment on, I can let you know!). Anyway, I built each module onto a separate piece of veroboard - each about 1.5"-2" by 4"-5" - and they all work. I am not liable for any damage that anyone incurs by building these circuits. A midi-cv converter could be built based on these circuits, but I'll leave that design up to you! Any questions, comments, gifts :), can be sent to me at this address: jat5@york.ac.uk Have fun!
