Hey Jbz
I'm not sure if this is what you want, but if you convert a midi note to
frequency [mtof] then multiply by integers, you get the natural partials.
So if you multiply the outlet of [mtof] by 2 3 4 5 and 6. then you can change
the multiplication figure, etc. I think that's the effect you're after.
God bless

Subject: [PD] making scales from frequency values
Dear all,
I have five chimes. I've worked out the frequencies (using Audacity) of the 5
strongest partials of each chime. I now want to be able to work out how to
change the octaves of the various partials? My original intention was to find
the nearest midinote and just use those but after listening to the results I
would much prefer to keep the original ratio's whilst being able to alter the
'inversions'.
Here's the list that I have already:
BT1
912Hz
2434Hz
4575Hz
7175Hz
11584Hz
BT2
1081Hz
2861Hz
5339Hz
8325Hz
15209Hz
BT3
1211Hz
3196Hz
5935Hz
9199Hz
15206Hz
BT4
1347Hz
3553Hz
6569Hz
10128Hz
18139Hz
BT5
1812Hz
4699Hz
8525Hz
13264Hz
15469Hz
Is there one piece of mathematrical wizardy that can sort this in Pd?
Cheers,
Jbz
