I said this while sleep-deprived....now that I've had a big jug of coffee I'm thinkin' it might not be quite exactly right. I'm not sure that BeatSync works with the old pulse type clocks. Pulses sent by metronomes or drum triggers or whatever, sure. But I'm not sure about those old clock lines. Does anyone know more about how those old clocks work? How many pulses are sent to define the time? It's possible it works, but I'm starting to doubt it. Matthias would know. BeatSync uses pulses to define the cycle time for the loop. So you might hit a drum trigger to define the start and stop times. (or the cycle times, if you are familiar with how the echoplex deals with cycles/multiplies/sync; meaning the total length can be some multiple of the defined cycle time.) If it turns out I'm wrong about the pulse clocks, sorry if I misled you.... kim >> It >>also works >> >with other pulses, like drum triggers.
