Re: [xpantastic] Pedal confusion

Hi Tony !

It�s possible to connect momentary switches as also pedals w/ a pot inside to the Xpander.
A Moog CV-pedal Modell 1120 p.ex. or a Oberheim OBX-P pedal.
Both, switches or pedals, need to have standard 1/4" TS phones connectors,- but not (stereo) TRS ones.

Momentary switches and pedals can be routed as modulation sources Pedal #1 / Pedal #2 to any modulation destination like VCAs, Filter cutoff, resonance and so on.

There is a selection of standard midi controllers available in the midi page, assigning controllers like CC#07 (volume) or others to the pedals in addition, - but that doesn�t mean the pedals transmit these controllers, - it�s just the virtual "pedal inputs" which receive midi controllers, being routed as "Pedal #1" and "Pedal #2" to the modulation destinations.

Example:
No dedicated Pedals connected to the Xpander and "Pedal #1" in the midi page set to "volume CC#07",- means:

Any received CC#7 midi data is routed to pedal #1 and is only active if pedal #1 is being set up in a patch to modulate p.ex. VCA 2,- result = volume control by a midi controller.

No midi input, but physical pedal #1 being connected to pedal#1 input and routed to modulated VCA2,- result= volume control via the physical pedal ( not by midi).

hope that�s clear now ...

You would have to assign Pedal 1/2 to a CC#.
But I believe pedal 1/2 are intended to be used as on/off switches,
not sources that can vary a signal, as in a volume pedal.
I may be wrong.

If your pedal has a pot in it, try assigning it to CC7 in the xpander
and assign that to a VCA, see if your volume changes.
