How to set different octaves on a midi controller to control different synths?

[an-electric-heart]

Hi, I'm grabbing one of these guys

I've got a theory, I want to use the low E and A "strings" to control a bass synth in the C1-B1 area, the D and G "strings" to control a lead synth in the C3-B3 area ect. But I've never wanted to use one controller to control different synths before.

How would one go about it? It'll be for live use in either FL or reaper

Cheers, hope I'm making sense (I've got plans for an MGMT style band with just me singing doing all the 'music' on midi guitar and a drummer on my electric kit)

It should be as simple as putting all the synths you want to control on their own tracks, set to listen to midi from your controller of course, and using a note filtering plugin on each track in front of the synth to determine what synth responds to which range of notes it receives from your controller. Reaper should have a JS plugin called "midi_note_filter" bundled with the install which should do the trick nicely, but a quick search of the net will probably turn up plenty of other midi note filtering plugins you can use in FL or other hosts. Insert Piz ( http://www.thepiz.org/ )probably has one in that obscenely large and useful collection of midi tools so that's a place to start too. Hope that helps!

Edit: I should add that you might want to use a note transpose plugin in your chain (after the note filter) to control which octave of notes you want to be able to play on each synth, especially if the synth doesn't have its own octave setting. You could even automate the transpose control to move the octave up or down with a knob or some sort of host-generated automation to give you more flexibility while you're performing.

Alternatively, see if your controller instrument can assign a different MIDI channel for each "string". If so, you can set each synth (or rather each track) to receive from the channel of the corresponding string. Then the individual strings are linked to the different synths even if the range of notes overlaps.
