Hi Hans

> Perhaps you´re right. I meant MATRIX with pins as on the EMS

I definitley do not recommend a Pin Matrix for the use in a
Audio-Instrument. The crosstalk between the different rails in such
matrix devices is quite annoying. I once bought a Ghielmetti matrix
(which is the state of the art producer) and I used it in my Formant for
a year or so. You could hear always the unused VCOs and the LFOs via the
crosstalk.

I plan to insert this matrix to the Doepfer vocoder system, because a
crosstalk is not disturbing there (all rails carry the same signal in
principle).
