Emagics Sascha Kujawa once posted his method to adjust it, here it is: 1. make a MIDI Sequence with a click sound at e.g. bar 4 2. record the audible result via audio 2a. double click for sample editor and ckech the distance of the first signal appearance to bar 4 to get the recording delay. E.g. if the signal is 400 samples too late, set RecDelay to -9 (ms). 3. place the anchor at the start point of your audio to place it manually at bar 4 4. pan you audio to hard left and MIDI to hard right 5. play back and record both onto a new track 5a. double click for SampleEdit and check the distance between both signals to get the PlayDelay. E.g. if the the re-recorded audio is 200 samples too early, enter (+) 5 (ms) at PlayDelay. That's all and takes only 1 or 2 minutes... Some people dont like this, because I am "compensating" the "MIDI delay" (maybe 1 or 3 seconds), but I think it's a real life measurement... ----------------------------------- He also answered another question that might come up: >How do you obtain the value in ms from the number of samples??? >200 samples late = +5ms -> 40 ?????? >400 samples early = -9ms -> 44.4444444 ????? Assuming you are running SampleRate 44.1k means there are 44100 samples per second, means 44.1 per millisecond... -------------------------------------------- Sascha (non-Kujawa)<< Hi all, First of all thanks Sascha for your answer to my question. After applying step 1 - 5a I found out that this what not the problem. This afternoon I recorded some tracks and found out that it seems like the recorded tracks are slightly faster than the original tempo. The song is 104 and the new tracks maybe 102. So the first few bars they seem in sync but after the next couple of bars they keep getting faster. I'm sure it's not me because I had the same problem earlier while recording saxes and trumpets. My setup: LAWP 4.04 PIII 450, 258 MB Isis soundcard Jack.
