Re: Using and expression Pedal on Midi Controller

From their website there are two 61 Impact models. The GX has no mention of an expression input only a 1/4" socket for a 'foot switch'. Likely to be just a Tip and Sleeve plug (mono - guitar plug). The GXP on the other had has a 'foot switch' and a 'expression' socket. This is likely to be a Tip Ring and Sleeve type of 1/4" plug (stereo headphone plug). Generally you need 3 wires for an expression pedal (many values from 0 to 127) Ground = sleeve, value or wiper = ring and voltage = tip . So my guess (I couldn't find a manual) is that the 'foot switch' can never have more than two values, 0 and 127, that is off and on. Hope that helps Royce
