hi all, i'm having a tough time keeping my osc's in tune, here's what i'm experiencing.

using the a190 cv1 output i'm able to acheive proper tuning up and down a 5 octave range
when using only one osc. when i patch in a second osc the pitch gets dragged down due
to what i assume is cv current drain.

so i bought an a185 buss access module to act as a buffer. i assume that when a single
osc tracks correctly from the a190 that the a190's scale is set correctly. so now when i
patch the a190 cv1 output to the a185 cv input, the pitch jumps upward a semitone and
the range is all out of whack (too wide). so now back to the a190 to adjust scale, the scale
remains too wide and no matter how many times i press the "-" button, the scale does not
decrease further.

fyi, the a190 and the a185 are in different frames and the cv busses are not connected
together outside the a185. also, my osc's are in the same frame as the a190. my osc's are
not doepfer osc's btw, they are analogue systems rs95's. could this be a response
problem i think not sine the rs95 tracks beautifully when only one is connected to the
a190 but who knows. the problems begin when i patch in the buffer, or when i patch a
2nd osc without the buffer. once the buffer is connected, the behavior remains the same
regardless of haing one ocs connected or two, so the buffer is doing 'something', just
throwing the scale all to hell and causing me to retune middle 'C'.

is there something obvious i'm overlooking here any help is much appreciated.

thanks, -psm
