Sorry for the late reply. Wanted to double-check this first before replying.
This seems to work pretty well but indeed is not “sample perfect”. ReWire’s transport sync is not based on samples but on beats, beats which are represented with floating point numbers. This is by design a bit fuzzy. Depending on the tempo, how exactly tempo and loops are interpreted in the hosts and various other little details, you will get small shifts here and there within all hosts that are synced with ReWire. So this is expected, and OK as long as those errors are not getting too big and do not sum up.
But if you are experiencing something else, and have a concrete example of where it goes completely out of sync, share an example (RNS and/or Ableton song) with us please.
Okay. It’s worse when using block loop mode. I’ll post steps and an example… but if you think it’s in the realm of acceptable error and can’t do anything about it, I’ll understand. And thanks for looking into it
Description
Renoise and Ableton get progressively out of sync when using block loop mode
Steps to reproduce
Make a 4-bar sequence in Renoise, set it to loop.
Record the 4 bars into an audio clip in Ableton’s session view.
Move the audio clip to a new track and add a phase invert utility.
Enable block loop in Renoise and loop the third bar in the sequence.
Play the sequence back, monitoring the rewire track in Ableton.
Expected results
Complete silence - the renoise track and inverted clip should null.Or maybe a pop because apparently that happens
Actual results
Silence the first time the loop plays, and then the loop gets progressively out of phase.
