As far as the example above, if you were at F/120, and you pitched up to G, the bpm should (if I did my math correctly) resemble 134.7 >> Keep your book open, Let's say the pitch/key of the second track is G at 130 BPM What pitch/key is the second track at 120. Not doing the math and just looking at your numbers, it seems to be a quarter tone flat? of F. (134.7 - 130 = 4.37 which is about 1/2 of 7.33 (new math;) or about a quarter tone. I don't think a BPM/pitch chart would be very accurate because they wouldn't translate into "exact" pitch/keys. When I hear key modulations in DJ mixes - If it's in tune - I assume that BOTH track have the same BPM and just the keys are different. Good reason for 16 bar drum intro's and outtros! Mixing by "keys" would be a lot harder and you don't get matching BPM's. I wonder what keeping the same key and BPM up or down sound like. Would make for interesting crossrhythms! mediadrome
