I'm having issues in Reaper 6.28 getting the manual recording offsets to remain consistent between projects. It seems to change at random. Maybe I'm misunderstanding or doing something wrong?
- Windows Driver ASIO Buffer Size set to 128 samples Safe Mode checked.
- Hardware Setup menu USB Buffer Size on the Axe-FX III is set to 256
- Tbh, I'm not sure I understand the Axe-FX Hardware's USB Buffer Size purpose...
- Reaper set up with "use audio driver reported latency" and adjusting for the offsets as described below
Here is what I am doing in a blank project:
Track One, routed pre-fader to Hardware Out 7/8 (IN USB block). Mute master send. (There is click track audio on this track)
Track Two set to record from USB IN 1/2 (Output 1 block)
Hit record a few bars ahead of where the click audio starts
Measure the # of samples offage and enter into "input manual offset" in Reaper options. In this particular case, the value was 998. Re-record and it lines up where it should.
Open a different existing project, leave the setting at 998. Do the same test and the 998 offset is not accurate for the new project. If I go back to the original blank project and repeat the first test, the 998 value no longer works properly. I have been chasing my tail for a few days trying to figure out what's going on.
Am I correct in understanding that this must be done separately for each project or am I just messing something up?
edit: Sounds like I am having the same problem as @steadystate here:
