That must mean STEREO! Will this cause the length of available loop time to be cut in half to process left and right? Also, will you be able to mute or replace any of the 4 loops on one page, say you wanted to mute loop number 2 on a page and leave loops 1, 3, 4 still playing or even replace loop 3 while still hearing the other loops? Will this be possible? I can definitely see where odd loop sizes could mess up trying to sync across pages. Maybe you could have an "un-synced" mode where each page could be as long as wanted or needed and you since you are not syncing you don't need to worry how to sync from one page to another. Just starting page 2 at the loop boundary of loop 1. Maybe in a "synced" mode if the second and subsequent pages were some multiple of the first such as half , twice, 3 times etc. or maybe even +1, +2, +3 , so if page 1 is 4 beats long, page 2 could be 5 or 6 or 7 beats long, maintaining the common quarter note pulse? This would let you have a 4/4 page followed by a 5/4 page. I could see some practical applications of this, but maybe it's too weird or hard to implement. Bob again: >Ed, I not exactly clear on why you are having so much trouble >syncronizing the second loop. If you are using multiple loops, you >should always "Tap" on the first beat of the loop.

When I sync to a drum machine , there is no problem lining loops 2, 3 4 etc. up to the pulse, because the drum machine is my "click track". Suppose I want to strum an acoustic guitar loop without using a "click" for timing, say a one measure A section in loop 1, obviously at the end of loop 1 I can have loop 2 cued up to start recording, so it's not really the starting point of loop 2 where the problem is, it is the ending point of loop 2. Say loop one is exactly 4 seconds long. I think I have decent timing but humans aren't perfect so without a "click" track when I play, maybe I finish loop 2 at 3.98 seconds, so now there is a tiny gap at the end of loop 2 which is noticeable when I switch between loops, as well as if my loop 2 is a little longer than loop1, then loop 2 gets chopped off a little at the end. Is this a little bit clearer? That's why for me at least, there are times when I don't need or want to be synced to anything and letting each loop be its' own length would be very useful. Thanks for your time and allowing us to give you some input. I really look forward to the upgrade. Oh, by the way do you need any beta testers? ;-) Ed
