Hi Manuel,
I figured you must have been a guitarist. You worked those functions out so easily.
The only way I can work out what a guitar mode function does, is record it it into a sequence, then check the resulting notation in a pc sequencer. Cumbersome,haahaa

We watched an amazing spanish guitarist the other night on Foxtel TV, a musician by the name of Benise. I'd never heard of him before. He was brilliant.
