in Re: utf8 hash keys revisited: How can i use musical symbols as hash keys?, Laurent_R mentions "I am really not convinced that a virtuoso violonist or cellist, or an opera singer, would consider them as equivalent and would play exactly the same tone"

Then in Re^2: utf8 hash keys revisited: How can i use musical symbols as hash keys?, you mention "Some do and some not"

Since MIDI notation does not directly support enharmonics, one way this can be emulated is via after touch. Even if the MIDI is not sent to a synth (hardware or software), the nuance represented by after touch is still within the realm of the concept (however imperfect the emulation).

Hi RonW,

thank you very much for clarifying this.

I didn't do any MIDI stuff yet, so i wasn't aware of this. But your hint will be mentioned in dispatches ;-)

If you are interested why i do this:

Update: ...and i'll fix the wrong octave in my OP ASAP ;-)

FWIW, just to clarify in case you do write about it. Aftertouch is not necessarily used for pitch change (though it’s a great use of it as RonW suggested and could indeed be used for microtonal stuff that given the quality/complexity of today’s sample engines could probably fool pretty much anyone). It’s just another control message and it can be assigned/used for anything. There is also a channel version of the control versus the single note message.

It is a very interesting project. Thanks.

PS My original reply could have been clearer. My appologies
