jstrauss Posted July 7, 2015 Share Posted July 7, 2015 I'm using a FC-7 with Mainstage organs and the default expression setting goes from 0-127 in a linear fashion. Does anyone have any suggestions on how to program it so it behaves more like a real Hammond pedal. For example, is there some setting other than 0 I should use for the minimum and should the response curve really be linear and if so how steep or is it more logarithmic in nature. Thanks for your help Modx 8, Motif ES8, Novation Impulse 61, Mainstage3, Hammond M3, Farfisa VIP-255 Link to comment Share on other sites More sharing options...
JMcS Posted July 7, 2015 Share Posted July 7, 2015 A Hammond pedal will not go completely silent at its lowest so you might try setting the range from 40/50 or so to 127. That is the easy part. A Hammond expression pedal does not raise and lower the overall volume evenly. High and low frequencies do not drop as much as the mid-range does as the pedal is moved from full to lower. High frequencies may be around 4kHz and above, low frequencies may be 120Hz or a little higher and below. As far as a curve you might try one that initially raises the volume a little faster than a straight line, crosses a straight line around the mid point of the pedal's travel so it raises the volume a little slower toward full and then raises quickly to reach full volume right at the end of the pedal's travel. Listen to your M3 and try to emulate that. Good luck. Link to comment Share on other sites More sharing options...
lerber3 Posted July 8, 2015 Share Posted July 8, 2015 I understand the need to set the limits of the pedal, but does it really matter if the 'curve' is correct in the middle of the pedal range? You press the pedal as far as you need to get the sound you want. Link to comment Share on other sites More sharing options...
WesG Posted July 8, 2015 Share Posted July 8, 2015 It does if you're one of those guys who constantly sculpt the sound of each note. These are not volume knobs.

JMcS Posted July 8, 2015 Share Posted July 8, 2015 Also, if the expression pedal also controls the amount of overdrive the curve can have a great effect on how the overdrive changes (both tone and amount) as the pedal moves. Link to comment Share on other sites More sharing options...
Tusker Posted July 9, 2015 Share Posted July 9, 2015 Yep, in the MainStage B3 model, overdrive is affected by the pedal. To the OP: do what makes you comfortable. You will almost definitely need to keep about 30% of level at the pedal's minimum travel just to get the dynamic range .... but beyond that .... customize it for your ergonomics ... you'll play better, and sound better.
