I have these same problems. Repeater does not seem to like slow tempos. I also had it go haywire switching from midi sync to beat detect or user sync. If I have a loop going and I try to tap at half tempo in user sync mode, say from 100BPM down to 50BPM, it doesn't do it. It actually changed tempos faster on me and then jumped around. Going from 200BPM to 100BPM I was able to do. in a reset loop, trying to directly tap in a slow tempo, say a 50-60BPM or slower, often doesn't work. Repeater doubles it. It wouldn't record a loop at all if the initial tempo was set with the knob to slower than 20BPM. It tells me "Tempo Slow". The beat detect mode doesn't work for me below about 86BPM, and that is using simple drum patterns. Oftentimes Repeater actually doubles the tempo! I guess doubling is better than using 86BPM for a 65BPM rhythm, which it did sometimes, but it seemed a little random what it would do. Tapping the tap tempo to help it didn't always work. at least not at these tempos. Generally the tempo detect worked better at faster tempos, in the "dance music" tempo range. I've also had it report half the tempo on faster inputs, like stuff over 200BPM. You can hold down the tap button to force Repeater to refigure the tempo. Sometimes that gets it sometimes not. Bebop at 250BPM always seems to be 125BPM for the repeater in Beat detect. When I tried to tap it, it gives 236-240. (Repeater stops at 240BPM for some reason, even though jazz doesn't.) When I record my drum loop in those situations it seems like the tempo matching thing sometimes loses it and the rhythm of the drums in the loop is a wobbly mess. One time what was a steady 60BPM pattern became a loop that drifted from maybe 90BPM down to 60BPM across the two bars, then repeated that as the loop... Another time I had a 200BPM pattern going and Repeater thought it was 134BPM. I recorded anyway without trying to fix it, and got another sliding tempo loop. I guess it is pretty cool that the tempo stretch engine in Repeater can do something like that and it still sounds like drums, but I would prefer to decide to have it do that rather than it just happen.... I tried a second time on that one, and that time I think the Loop Point Assist jumped in and did something weird, so my resulting loop point was not even close to where I tapped it. Maybe I had the tempo lock on for that, not sure. It would be nice if there was a way to turn off the Loop Point Assist thing. Beat detect works better at faster tempos. It picked up 100BPM ok. But when I record a loop in the Beat Detect mode and play it along with the original to check the timing it flams a lot and drifts around the beat. (I have that same problem with midi sync in.) I guess that is ok if your music isn't very tight rhythmically, but to me it was irritating and affected the rhythmic feel. I suppose you could tweak it with the slip or trim functions to get it right in the studio, but I was looking at this for live use, and it's just not accurate enough. Repeater doesn't seem to like it if you try to make big tempo changes on it with taps or the beat detect. It does follow if you change it slowly, which is nice. So for an unsteady rhythmic source repeater would be nice for tracking it and keeping the loop in sync. It gets lost on big jumps though. If you tweak around with it enough you can get it back, but it takes some effort. Switching from midi sync to Beat Detect or User Sync also sends it all over the place. All these tempo detect and tracking features seem like pretty nice ideas with great potential, but they just don't work well enough for the sort of live, improvised approach to looping I like. In a studio application where you are doing remixes with different source samples, and you had time to tweak with it to line things up right and avoid the occasional erratic jump it would be pretty useful. But for live use it has to "just work" with a minimum of extra user tweaking and so far I'm not getting that. kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@loopers-delight.com | http://www.loopers-delight.com
