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 Andrew

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
