 [Bluemusic-users] pitch notation and the tuning processor From: Paris - 2004-10-11 14:07:37 ```hi steven and blue users, i'm back with more questions relating to the tuning processor although it's also my inexperience in using pitch class notation. before that though... steven, thanks for the python links. i've been learning it on my daily commute, not bad! also for the line of code checking if the note value is <15 - i've been using that for my instruments now. question one: does pitch class notation imply 12TET? for example, if i create an instrument with pitches: 8.00, 8.01, 8.02, .... 8.12 i hear what appears to be 12TET with 8.12 the octave of 8.00. going past 8.12 to 8.13, 8.14, .... 8.24 repeats. sorry, i know this is a "CSound 101" question but i never really got this and always used Hz for my pitches. question two: so assuming that i have pitches 8.00 to 8.12 (or beyond) and i now apply the tuning processor using a scale that is larger than 12 tones, e.g. partch_41 - what is happening. i hear the frequencies have changed but how would i go about writing my score so that a note in pitch class notation maps to a specific note in the scale? e.g. let's say i want a note in the score to play (after processing) the 35th note (16/9) of the scale. what value would i use in pitch class notation to do this? thanks so much, paris ```

In pch, 8.00 is equivalent to middle-c. Using the tuning processor, if you use partch_41 and want the 35th note above middle-c, you would use 8.35.
