Subject:Beatmapped without preserving pitch Posted by: ttm Date:12/13/2002 6:32:30 PM Hi all, first let me start by saying that I like the concept of beatmapping tracks. I know Acid 4 has its downsides with respect to drifting tempo etc. But it saves a whole lot of time...However, I'm not clear on the following: Let's say you have beatmapped a track and determined its tempo at 125 bpm. Your project however is 127 bpm so Acid makes up for difference in tempo. Acid can stretch the audio while preserving pitch (classical timestretch stuff) or stretch without preserving pitch (resampling). Now here is my problem, if you disable preserving pitch in the track properties, shouldn't this sound the same as changing the track type to a one-shot with pitch shift enabled? Well it should and it comes close, but it doesn't. After disabling preserving pitch Acid still treats audio tracks with some form of stretching which is clearly audible. So is there a way around it? Sure, it can be done by changing a beatmapped track to a one-shot then using a pitch-shift on it. But for each track this shift has to be typed in manually since the tempo info somehow gets lost by changin track types. But there is a downside to this solution: if your project contains a tempochange then the events on a track before the change don't match the ones after it. (Because you changed it for all events on that track...) So what would I like to see then? Well it would be nice if one disables preserving pitch on a beatmapped track, that all events on that track are treated in the same way as one-shots do with a pitch shift. A simple resampling... ttm
