I thought of that, in fact I just purchased a WIDI jack, (bluetooth MIDI controller) for the HELIX so I can use Forscore in my iPad via the WIDI jack, to automatically change to the appropriate snapshot and tuning when I select a song on Forscore. My only obstacle is that I just finished building a new pedalboard centered around the Helix. To make everything fit, I had to build a riser for a few pedals, which blocks the top of the Helix, I installed remote 1/4" stereo input jacks for the output. I'm pretty sure that to send MIDI to and from the Variax, that the cat5 cable has to be used, which as I said is not accessible at this time. I have to look into a remote surface mount for the cat5 also the XLR/AES outputs, (I run 2 PC+'s in stereo). It seems that just as soon as I get everything all set...I have to change things for one reason or another, never changes!
