At first - I think there are some midi-violins with well-balanced systems and nearly perfect function - and a very expensive price (3000€ and higher). So what I can expect about a little box under 100€ for guitar? Just an experiment - how usable will it be with violin?
So I bought the little Box G2M V3 with low expectations, want to try what is possible with my existing equipment. I suspect, a electric violin will be better than a acoustic, because the sound is more flat - in acoustic violin there are more resonances from the corpus and this will disturb the box to translate into midi. My old ZETA-Violin (a simple model, passiv pickup) and my old Korg M1 Synthesizer (has normal midi sockets like G2M) I used to probe whitch parameters will work to give the best function.
