The Moog Werkstatt-01 uses patchwire cables so I thought some people would be interested to see if it's compatible with AE Modular.
I had a look at the manual, this is the section that is relevant in terms of compatibility:
I'm not an expert so correct me if I'm wrong but I think this is the situation:
* VCA IN when set to EG mode uses -/+ 2.5 v so it's not compatible
* VCA IN when set to ON mode uses from 0 to 5 v so it's OK (but obviously you can't use the onboard EG)
* VCF IN cutoff uses -/+ 5v so it's not compatible
* VCO LIN IN this is linear so it's not compatible
* VCO EXP IN uses 1V/Oct but it's -/+ 5 v so the "note pitch" would be correct but you have limited range
* LFO IN using values from 0 to 5 v you will have the same range as the on-board knob, if you want slower cycles then you have to use negative values (total range: -/+ 5 v), so I guess it's OK as long as you don't need those slower values.
* KB CV OUT needs attenuation in order to do 1 v/oct
* TRIG OUT, GATE OUT, EG OUT and VCO OUT seem OK (they are all 0 to +5 v)
I just realised that the VCO LIN IN could be used for linear FM rather than pitch control, this wouldn't be compatible with AE Modular either, because the signal would need to be attenuated since the VCO LIN IN expects a lower range voltage.
Hello I'm a future new user of AEm, and i've already have a Werkstatt (with cv expander, but i prefer patch it with jumper cables ) .. Would be glad to use it, even limited, with my AE system... What would be the common mistakes that could cause issue on both devices ? If the AE receive negative voltage or the werkstatt over voltage on , e.G the VCF ( -2 , +2V- will they break ?
With the use of attenuators and inverters to "maintain " the voltage between 0 and 5 V , would less risky to make them interact ? And therefore, what kind of AE modules would I need to control this ?
As you've stated above, some of the outputs of the Werkstatt are below 0V or above 5V and you would probably break your AE modular if you would patch those into any AE module directly via the small patch cables.
The only safe and recommended way to interact with other systems that are not 0-5V is via the 3.5mm I/O jacks on the Master, Power and 4I/O modules.
While you could take extra care to attenuate a signal on your Wekstatt before it goes into the AE ... I would warn against this approach as you could easily accidentally touch a knob and change the attenuator and *bang* there goes your AE.
The same applies to the Korg Volca Modular, which also uses the same patch leads, but also sends voltages that are incompatible with AE out of the box (however an interface module is in development).
