Okay, if it's a TS plug then we're very probably talking about a CV pedal
instead of an expression pedal. I would suggest the trick I mentioned
earlier to convert a volume pedal to a CV pedal and see if that works --
you're talking a buck or two for the battery connector.

Subject: [oberheim] Re: expression pedal for Matrix 6



I plugged a Yamaha FC7 into the Pedal 1 jack--the Matrix 6 senses it and
will transmit the appropriate CC# via midi to my computer but only for value
0-14 (i.e. out of 0-127). The pedal doesn't have any audible effect on the
Matrix patches even when programmed appropriately, which leads me to believe
it's a problem with the pedal or the Pedal 1 jack.

Is this the wrong kind of pedal The manual says you should a standard
guitar cable for the input (i.e. TS plug ) but as far as I know all
expression pedals use TRS plugs.

Any suggestions Anyone ever get Pedal 1 to work on the Matrix 6 or 6R)

conclusive... maybe my pedal #1 jack is broken, or maybe the EV-5 hasn't got
the right capacitance or polarity for what the Oberheim Matrix 6 is
expecting -- though if the polarity was wrong, it just would work in the
reverse fashion. The EV-5 also has a sensitivity knob on it... adjusting it
made no perceptible difference.
