Sustain Pedal to Sostenuto - Midi Translation

I have a Midi Controller with an sustain pedal (exclusively) which works perfectly with my Piano VSTs. But now I need to use sostenuto on some piano pieces. My idea was to use another small midi controller and use its sustain input. I would like to add a new track where i use a small plugin which translates the sustain from my second midi controller to sostenuto signal and send it to the track where the main piano controller is configured to work with the Piano Vst. Do you know any Plugin that can translate CC#64 (Sustain) to CC#66 (Sostenuto) .

What? CC64 is CC64, no matter how you call it :)

Hi, I've written a plugin that (among other things) makes cc64 act like a sostenuto pedal for whatever midi instrument follows. As soon as my kids are back in school and I get a few moments of peace I'll double check it works and link to it here. :) Cheers!

Hi Peter, Sorry it took so long. Hope this helps:

JS MIDI CC Mapper is part of Reaper.

The js midi cc mapper will work if the sound source responds to cc66; my plugin emulates the sostenuto behavior and can be used with any sampler, synth, etc.

how to translate (convert) CC#64 (Sustain) to CC#66 (Sostenuto) . 

This tread exactly about this You need to convert it, with "Midi convert to CC" plugin. (can be downloaded with ReaPack, that need to be installed first)
