RC-50 latency problems.



The latency problems I'm encountering with the RC-50 are not the glitch problem that others seem to call latency. What I'm experiencing is a slight "behind" effect of the recorded phrases in relation to a sequencer or drum machine that is slaving to the rc-50 (although the same effect happens when recording with the guide track). It seems to happen when the unit is in either record or overdub, and disappears when in playback. This effect destroys any groove feeling. It's not much-perhaps 8 to 12 ms- but it's too much for me! I was getting the same thing with my EDP too, which is one of the reasons I wanted to try the rc-50. If I run the midi clock through my fadermaster, which has a midi delay feature, then into the drum machine, and set the midi delay to about 10 ms it brings things back into the pocket, but then you have to keep resetting this delay when you want to either record a new loop or overdub again or it compounds the problem (obviously too complicated a "work-around" to be useful as the idea is to make looping easier so as to concentrate on playing music.
     As far as slaving the unit to the drum machine - it's hopeless. My old JAMMAN can do it rock solid- why not this rc-50. It's unusable as a slave. If you don't believe me, try recording the drum track from the master machine you're trying to sync to, then try to play them in sync.
     As far as I'm concerned, unless they fix these two problems- especially the "behindness" or latency in the recording and overdubbing, this unit is not for those who want to be in sync. And according to the folks at Roland support, there is no software fix in the works that they know about- not even one for the dreaded glitch that others seem concerned about-- which is unfortunate, because there are so many other great things about this unit. I found the EDP controls too convoluted for my needs. Too many switches to push just to start a loop.(in sync).
     Is there a machine out there that can loop in sync- in the pocket- without some ridiculous new problem to contend with?
     Very disappointed. Back to the EDP but not happy about that. Maybe I'll go back to my Lexicon PCM-42 cause at least I can groove with it. Except that it only has 20 seconds. The Jamman only 32.
     Shit. I thought I was upgrading, but if you can't stay in sync with these new units, all the other bells and whistles are just that.
     Hope this is useful and not too depressing.
