Is this being used in live performances? If there are other musical sounds would it not work? I would really be happy not have to drag out the laptop and be subject to the variables it might bring. How about this in an effects box? Just plug the mic in and take a line out.
Yes, it's possible to use imitone for live performance---though doing this requires very careful setup of the microphone.
As to a hardware solution, it's a possibility but not something I'll investigate until after the software is complete. In the mean-time I will be developing mobile versions of the software which may suffice.
