Hello,

I'm facing some issue with module A138e, in the three way crossfader mode.

The patching :

I have in the A138e an S&H output (input A), an LFO square wave output (input B) and a QRV A149-1 output (input C).

This is modulating a VCO.

If the potentiometer is fully ccw, I should get only the effect of the S&H, BUT somehow the S&H is affected by the LFO.

The LFO itself doesn't seem to be affected by the S&H or the QRV.

The QRV is also not affected by the other modulations.

I tried on different inputs of the 138e and same thing occurs.

If I plug only two modulation sources, like the S&H and LFO, it works fine.

With audio sources, at high volumes, I have some leakage also, like for example with high resonance values from 106-1 or 101-6 I can hear it on B when its in the A input. But this I can understand better and get the volume down.

Where it gets weird (back to the CV sources problem) is that if I unplug everything and re-patch, slowly, putting first input A, then input C, then having the module to work as a two-way crossfader and ONLY THEN add the input B, it works fine !

Just curious if there is any explanation to that or if the module is just not working properly (still under guarantee).
