I don't understand why the SooperLooper click gets delayed from Ableton's click after a while... Let's make that experiment (using latest Ableton and Sooperlooper, in standalone mode - not AU plugin) :
- run Ableton and standalone SooperLooper
- in Ableton, set your tempo to 120BPM for instance and in the preferences, activate SYNC for midi ports > output Sooperlooper_in
- configure Sooperlooper with sync To : MidiClock.
- run global transport in Ableton - you see that Sooperlooper gets the metronome clicks and then gets the right tempo BUT after a few seconds, you can see that the blinking "tap" is totally not synchronized with the Ableton's metronome. WHY ???
Thanks for your help !
