4.63 - midi pitch to frequency turns A4 into 430 HZ???
Hello again,
i'm converting Midi Pitch to Frequency for a harmnic resonator patch, but my formula seems to be wrong (or i am missing something else) since it turns A4 to a 430HZ float instead of 440HZ.
What am i doing wrong?
Here's an example:
Thank you for any hints pointing me into the right direction!

Why can't you use [mtof]? Or an [expr] that uses the same equation: [expr (pow(2.,(($f1-69.)/12.)))*440.].

Your formula isn't so much "wrong" as it's tuned to Middle C = 512Hz. Which is about 37 cents flat to the "official" intergalactic Chamber Tuning.
Whether it is "wrong" to tune to something other than A=440 is a different question. I live in Berlin. Most bands here tune to something between 444 and 447Hz.
Hello Peter,
(don't you do MAX workshops via Salon Bruit. I host their mailing list on my server, and i am in Berlin, too. When is your next workshop? :)
Regarding the middle C reference: How would i instead tune to A 440? And why exactly am i tuned to 512 Hx C now? i lack the principal understanding, sorry.
Regarding tuning of Berlin bands: Good to hear they don't use tuners. Any nonconformity will finally help to keep music interesting. I tune my guitar to the 50 Hz hum exhaled from all my equipment due to bad grounding. I think that leads to a similar, higher tuning at last. Luckily my piano refuses to follow this and instead tunes freely to the temperature changes in the room.

LH sorry totally overlooked your reply!
thank you much, will try this then!
