> Hello,
> Sorry if today I am trying to find answers about modules which are not Doepfer, I frankly guess that this list users can be more helpful than ES customer service. Moreover, due to my eyesight flaw, I barely can watch details on video tutorials which often are pedantic and verbose.
>
> I am intended to replicate an MS-20 typical patch on eurorack: audio signal driving a VCO and/or some MIDI instruments (external MIDI gear as well as software MIDI instrument, i.e. plug-ins).
>
> The MS-20 features a unique Ext Signal Processor which treats the audio signal properly in order to finally output cv and gates. 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.
>
> I think I have 2 options.
>
> 1) the first would be to keep using the MS-20 Ext Signal Processor and to translate the Hz/V into the 1V/Oct by means of the linear/exponential converter featured by the Disting Mk4.
>
> 2) the second option would be, overriding the MS-20 ESP, to use the pitch&envelope tracker, also featured by the Disting Mk4.
> This second options seems preferable to me, freeing the MS-20 ESP for other applications.
>
> Am I right
>
> In both cases, I also need to translate the 1V/Oct into MIDI pitch and the gates into MIDI notes.
> Can I take these signals (the envelope tracker output should be further treated via a comparator in order to obtain gates) from the Disting MK4 and send them to the Mac via the Expert Sleepers ES-8 inputs If yes, what Expert Sleepers plug-in (from the Silent Way Suite) should I consider in order to get the job properly done
>
> Moreover, how could I translate the differences in amplitude of the original audio signal into MIDI velocity Is this possible
