Title: Md16r
Post by: Billp on August 10, 2017, 01:13:20 PM

Hi has anyone fitted external triggers to a cheetah MD16R so the sounds can be triggered by external 5 v pulses ?
Ideas please Billp

The MD16RP had external trigger inputs as standard.
I have one but at some point someone has disconnected all the connections from the trigger input board and i have no idea where to wire them back in. The main boards from all of the MD16 versions are the same, but unfortunately the trigger board isn't on the schematics.
You'd need the MD16RP operating system.

Alternatively a 4066 wired across the front panel buttons would probably work.

Thanks my original idea was to use transistor switching accross the panel switches gong to a D type connector on the back panel
4066' s are more elegant idea
But I've got to fix the psi as only got 3.45 v on th positive logic at present
Will renew caps and reg
