I'm having varying problems with syncing songs in Acid. I have versions 8 and 9, and I have occasionally had this problem in version 7 too, but it has become worse and occurs more frequently than before.
I'm making projects mimicking beatmixed DJ sets. The Transitions between songs drift gradually more and more out of sync. If I start playing right before a transition, the first one usually is rather fine, but as playback advances, the drift is more and more prominent in every consecutive transition. When zooming into the waveforms, the beats are visually in sync and the beatmapping should be correct.
Originally this only used to happen if both songs were timestretched/pitchbended, but at least not noticeably when at least one song was only re-pitched. Also it was sometimes made worse if I had MANY inactive tracks with songs overlapping the transition, or if Acid occasionally decided to use a non-ASIO audio device. Now neither of these resolutions seem to help at all.
Am I running out of computing power, or should I go through the trouble of reinstaling the system, or is it an audio device issue? Or might the 64 bit version solve this? I'm curently running the 32 bit version because I use an old VST plugin that has no 64 bit option. I am using Focusrite Scarlett 18i20 for the palyback device in Acid. One thing that I find weird is that when starting Acid, in the splash screen it seems to list a plethora of old audio devices that are no longer installed, including Traktor Audio which I haven't had for years, and which I don't remember installing into this system.
