Thank you for trying to help me.
ShapedNoise, Cubase if you send MIDI Clock, in fact it's not the only synth I have, and I send it to others ( MatrixBrute, Virus Ti ...)
Terrym, I select the output of cubase towards the MicroFreak, even I have come to record with the in cubase data CC notes etc... what does not change is the tempo.
If I have the project at 120BPM and an arpeggio of MicroFreak is at 145 BPM, it can't be synchronized.
Thank you very much!
