I'd like to connect a pedal to the back of the M3 and have it do a cutoff freq sweep. Using 014 Super Analog Pad as an example what changes would I have to complete to go from using the left drawbar to the pedal? Thanks.

just change the midi map.

To control filter cutoff directly with the pedal, in Global mode, map the foot pedal to CC#74 filter cutoff frequency.

Some programs are set up so that the ribbon controller controls filter cutoff and other AMS parameters, giving a nicer effect than just controlling cutoff on its own, so you could try mapping the foot pedal to ribbon controller CC#16. I do this for a couple of songs with the Leader of Trance program.

In Combis, if there are some parts you don't want to sweep cutoff with the pedal, filter these out using the Midi filter for either Realtime Control Slider 1 or Ribbon Controller.

...thanks a bunch, that should head me in the right direction. This 700+ page double sided small text printed manual is somewhat daunting...

When doing this, is there any way to set the max and min values?
Because 0-127 is too much of a sweep for most of what I want.

Is it possible to edit the range of filter sweep associated with the ribbon controller or in this case the pedal assigned to the ribbon?

No, I don't think there's a way to set min and max sweep limits globally for a pedal. I use a Yamaha FC7 pedal, which has an adjustable detent for the maximum limit, and I'm careful about foot control for the minimum.

It is possible to edit the range of filter "sweep" assigned to the ribbon (or any other controller): In the affected program, go to the Filter 1 or 2 page and then the Mod. tab. In Korg terminology, any control sources like ribbon, faders, lfo etc. are known as Alternate Modulation Sources or AMS. In the Mod tab, you can adjust the Intensity (i.e. how much the controller affects the filter cutoff) for each control (AMS) source - there can be 2 sources for each filter.

This is where it gets really complex (but also very powerful!): Note that the ribbon may or may not be listed directly as a controller - it may be routed through one of the AMS mixers (which mix different control sources together) and provide effects like quantisation, smoothing etc. The smoothing can be quite useful when using the ribbon or a pedal, as it avoids sudden changes from accidentally touching the ribbon.

The control of any controllable parameter (filter, drive, attack, effect depth etc. etc.) by any controller (pedal, ribbon, joystick, switches, faders etc.) can be adjusted in this way.
