Would there be a gap if the tempo slowed >down and would it cut off the loop, if the tempo sped up? .... When the clock gets faster, the echoplex will retrigger it's loop early, so it won't quite get to the end, and when it goes slower, the beginning part of the loop gets played again before getting retriggered. (I think that's right, haven't done that in a while.....) If the clock changes too far, the echoplex will stop trying to sync to it and just loop freely. So once the clock moves out of a tolerance range, it ignores the clock. (It's assumed at that point that the clock change is intentional and not a random fluctuation, so sync is no longer meaningful.) If the clock moves back into range, the echoplex will usually begin to sync to it again. I'm afraid I don't remember what the range is...Probably +/-10 BPM or something. If you're just looking for something that conveniently varies midi clock tempo, try an old Alesis HR-16 drum machine. With the data slider controlling tempo, you can smoothly slide the clock all over. You can even do fine adjustments with the up/down buttons. Very handy, even displays the BPM. I'm pretty sure a used HR-16 will be a lot cheaper than a midified EH 16-sec delay...:-) kim ________________________________________________________ Kim Flint, MTS 408-752-9284 Chromatic Research kflint@chromatic.com http://www.chromatic.com
