I am trying to sequence the model D via Voyager/Vx-351/cp-251/mp-201. So far I have got the gate/s-trig to work fine. The issue I have, and thanks to Kevin Lightner for his input on an earlier thread, is that the scaling on the pitch in on the model D is off. I have not disconnected the keyboard yet, but was trying to get it scaled without removing it. Is is possible to use the an attenuator to get the scaling right, or else is there a way to set the scaling in the Mp-201’s software? Once I do disconnect the keyboard, what is the reference I should use? Thanks in advnce.
