My scenario:
Waveform ReWire Master using as Recorder + Low Latency**.
Renoise ReWire Slave to work normally + benefit of live recording.
Issue: All bpm ZTxx changes are ignored for obvious reasons
Solution: Add ReWire “Sync Mode: Off”.
**when on pure laptop (no ASIO avalible) “Windows Audio” is giving me less latency than “DirectSound” - worth checking. For this reason sometimes I use this setup even when I am not live recording - just to get lower latency.
