I use it for that indeed. I use also the one with 4 samples, one for each formant.
But I wondered if there were something else, an other approach. No idea about what!
Thanks anyway. Alain
There is no manual for Nysthi modules. Sometimes these modules are emulations of Eurorack modules, and docs for some of them might exist somewhere, but then, it’s common for Eurorack modules to have no documentation either.
