Hi There! I've found a cool video on youtube where a person trigs a Boss DR by a sampled clock signal. At first i fought that such a thing would be impossible, as a clock signal is not a sound, but an amount of voltage. But ever the less some guy made it possible. HOW?!

BOSS DR-220e in sync with Ableton Live

You can sometimes trigger analogue clock inputs with a loud enough and short enough click sound, it certainly works with SH101's sometimes.. You could easily build a clock trigger waveform with some kind of audio editor. Amplify it enough and it'll trigger an analogue clock.

Or build a audio click to 5v trigger circuit if you wanted it to be more reliable.

The clock pulse is just a slow squarewave.  The clock input is probably edge-triggered anyway.

try using Goldwave's expression evaluator - it has a handy sq wave generator - u can specify speed etc... (it's nice for making beepy noises anyway )

there's MOTU's Volta nowadays..  software that will turn supported soundcards into CV drivers.

nice idea, bit pricey maybe.
