Is there any way to sync up Usine with another DAW? I want to output sequencer MIDI data from Usine to Reaper, but even with the tempos set the same, the timing is off between the two.

You could use MIDI Beat Sync. If you want Usine to Master, click the MIDI out in the devices panel...and in the settings panel there is an option to send MIDI Sync.
The same goes for your MIDI input port, you can also set that to receive. This will keep you in sync.You just then need to configure you DAW as Master or slave (send/receive).

Tobias Erichsen has a LoopMidi application where you can create virtual MIDI ports you can use to pass the sync between applications. I have this listed in the WIKI

Thanks for the quick reply! Think I got it set now.

Scratch that, I spoke too soon. No matter which program I set as the master, the timing is very stilted and produces extra notes. Are there any settings I can try in Usine that might help this? I tried changing bloc size but that doesn't seem to matter. I've demoed different settings in Reaper as well, but there's been no progress.
