this is sort of old, sorry. I need a secretary.... comment below: At 7:55 AM -0700 7/2/98, Dennis W.

You'll probably want to set it to a higher value, something that is more related to the loop time you are recording on there anyway. When midi clock is coming in, the Echoplex uses that clock to determine quantizing triggers for loop switching. The 8ths/beat setting determines the interval of clocks that go by for each quantizing event. When you have 8ths/beat set to 1 on EDP 2, it will quantize to each 1/8 note from the tempo set by EDP 1. When there is no midi clock coming in, it generates the quantize event for itself at the end of each cycle. So in this case, you actually are going into the waiting period, just not for very long. As soon as the next 1/8 note point comes by, it will switch. If you set 8ths/beat on EDP2 to 8 or 16, you will have a much longer waiting period. Another way to look at this is that The echoplex is determining it's cycle length from the midi clock and the 8ths/beat setting. So with 8ths/beat = 1 it is using one 8th note for its cycle time. When you go to record a loop on that echoplex, it will happily let you make that loop as long as you like, but from it's point of view the loop will already consist of many cycles when you tap record to end the loop. For example, say the midi clock determines that an 8th note is .25 seconds long (meaning bpm=120). You tap record to start a loop, and it begins recording at the next 8th note. You tap record again to end it at 2.0 seconds. From the echoplex's point of view, this loop is actually 8 cycles long, with each cycle being .25 seconds long. If you had instead set 8ths/beat = 8, the 2.0 second loop would be one cycle long, and might do more what you expect here. hope this helps, kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@annihilist.com | http://www.annihilist.com/loop/loop.html http://www.annihilist.com/ | Loopers-Delight-request@annihilist.com
