1. I'm color blind, and the red/green LEDs are impossible for me! I'd like some other color options, after all - many musicians are color blind, and red/green is the most common form. I know this would have to be a custom retrofit - but in future incarnations maybe. I should think this would be the case with the Alpha as well...
2. The keys are VERY sensitive. I'd like a software setting to adjust the response sensitivity, so that I wouldn't accidentally trigger notes.
3. The strap needs to be capable of being longer!
I think the instrument has great potential, and I'd consider moving up to the larger instruments if 1 and 2 were possible...
