Apologies if this has already been addressed. I didn’t find anything in a search.
Windows 7 Ultimate SP1
M-Audio Firewire 410
Automating the tempo track when there are time-dependent audio events produces a major lag. When inserting points on the tempo track, there’s a 10-15 second delay.
Step 1: Create audio track
Step 2: Import something long-ish like a full song and place it on Track 1
Step 3: Check “musical-mode” on the song in the pool
Step 4: ctrl+T and draw tempo track automation - Doing this should produce a significant lag
This may or may not get worse depending on how many warped tracks there are in the project.
