Instrument-specific tuning profiles for more reliable tuning

Select the instrument you're tuning before you start. This could improve the accuracy with non-guitar instruments, e.g. Cello, since currently the algorithms are optimized for guitars

Merged "Core: tuning profile for brass and woodwind" #548

"Have a setting dedicated to Brass and Woodwind instruments (slower reactions and set transpositions) as the current settings react instantly to slight changes in pitch."

In order to make this core2 actually useful for woodwind and brass instrument players, the tuning function MUST be optimized for these instruments as well. Putting a mic in the core2 would seem to make this application obvious.

"The fact that there is only support for stringed instruments is such an oversight, the tuner doesn’t pick up any pitches for my flute. This was the PRIMARY reason I got the watch, and its ridiculously frustrating that I can’t even use it for this purpose. If the higher pitched string instrument settings do not work when I try tomorrow, I will be returning my watch."
