yes, it doesn't really matter at all for this kind of system

you can set it to zero, to negative one... possibly to the imaginary constant

because this library does not actually make any sound. it's (to me) an implementation of 12tet, the standard western scale system which includes a bunch of scales and approximates the rest 'well' enough

I don't mean to lose my 'temper' here, but I think gp is hoping Note.freq(), Note.fromFreq(), etc. aren't locked into A440 as the examples imply. While >99% of the library doesn't deal with this at all, it would be handy nonetheless. Unfortunately, it's currently hard coded:

https://github.com/tonaljs/tonal/blob/main/packages%2Fmidi%2...

Imaginary constant... complex tuning here we come!

The ideal tuning isn't 440hz, it's (440+42i)hz /s

up there with negative probability frequencies

Isn't that just 442Hz, except about 34.3μs early?

Would the delay vary by pitch? (or would i also have to increase for that to be the case)
