Hi everyone from London. I suspect this is already a feature which I missed but I was under the impression that in midi omni called mode you had to keep your fingers down on the chord on your MIDI device whilst playing the sensors. Well it appears on mine not only do you not have to keep playing the midi notes, the sensors actually remember the tuning so effectively you can apply any tuning to the sensors that you want really easily and then have all the functionality of the instrument that on more conventional scales as well!
