Some workaround to sync Cubase with your modular synth in a way to correct the audio input latency.
Cubase doesn't have a midi clock offset like ableton live.
Very useful for the beatstep pro and some other tools you may use in the same way.
Using midi gates, clock signals and envelope generator.
I'm using here Expert Sleepers Silent Way plugins and the Expert Sleepers interface ES-3.
Also using Gatekeeper to send envelope signals.
Thanks voxengo for their free plugin "latency delay"
