Hmmm. It just got stranger. If, with AUTORECORD on, I end recording loop 1 by hitting next loop and immediately record loop 2, the Alesis and the EDP will stay in perfect sync when switching between the two loops. If I end loop1 by pressing record again then I will eventually have my sync problem. I'm including a copy of my original post below. I'm hoping this all sounds familiar to someone. Thanks!!! Michael Original Post: Sigh. I've read the manual. I've searched the archives. You are my only hope. SYNC=in QUANT=loop SWITCHQUANT=loop 8THS/CYCLE=8 MORE LOOPS=2 SAMPLERSTYLE=run My Alesis drum machine is sending MIDI clock, and is set to a simple 4/4 pattern. I record loop 1, no problem. I record loop 2, no problem. While playing loop one, I press NEXTLOOP. The Echoplex thinks (000), then changes flawlessly into loop 2. While playing loop 2, I press NEXTLOOP. The Echoplex thinks (000), then instead of changing at the end of loop 2, it starts loop 2 over (even says so on the LED) and gets about one or two beats into the first measure before changing back to loop 1. I am losing my mind. If it's the MIDI clock from the drum machine, then why does it change flawlessly from loop 1 into loop 2? I can just turn off the SWITCHQUANT but this means I have to tap NEXTLOOP on the proper downbeat, and I would prefer to let the EDP handle that while I'm busy adjusting my effects pedals. Help me. Please, help me.
