Doepfer

Just checked the Disting 4 manual for the latest firmware - have a look at algorithm A-5 for the converter.

Of course, it cannot be used to drive eurorack VCO’s 1V/Oct input (exponential), since it delivers Hz/V (linear) and I didn’t find a reliable eurorack module for this job.

If yes, what Expert Sleepers plug-in (from the Silent Way Suite) should I consider in order to get the job properly done?
