What makes the Vibrandoneon special is that it is essentially a high quality accordion. I don’t see where a plastics company like yamaha et al can step into that quality niche.
I’d die to to get Guido Tonini’s hit on all of this.
But for now my focus turns to
1) security (cable system and lock integrated into the case
2) protecting my instrument from lung moisture
3) identifying resources for maintenance (reed replacement, tuning etc.)
