Hey Jbz<div><br></div><div>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. </div><div><br></div><div>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.</div><div><br></div><div>God bless</div><div><br></div><div>Andrew</div><div><br></div><div><br><hr id="stopSpelling">Date: Mon, 20 Jul 2009 22:24:05 +0100<br>From: jbeezez@googlemail.com<br>To: pd-list@iem.at<br>Subject: [PD] making scales from frequency values<br><br>Dear all,<br><br>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'.<br>
<br>Here's the list that I have already:<br>BT1 <br> 912Hz<br> 2434Hz<br> 4575Hz<br> 7175Hz<br>11584Hz<br><br>BT2<br> 1081Hz<br> 2861Hz<br> 5339Hz<br> 8325Hz<br>15209Hz<br><br>BT3<br> 1211Hz<br> 3196Hz<br>
5935Hz<br> 9199Hz<br>15206Hz<br><br>BT4<br> 1347Hz<br> 3553Hz<br> 6569Hz<br>10128Hz<br>18139Hz<br><br>BT5<br> 1812Hz<br> 4699Hz<br> 8525Hz <br>13264Hz<br>15469Hz<br><br>Is there one piece of mathematrical wizardy that can sort this in Pd?<br>
<br>Cheers,<br><br>Jbz<br></div><br /><hr />Windows Live Messenger: Happy 10-Year Anniversary—get free winks and emoticons. <a href='http://clk.atdmt.com/UKM/go/157562755/direct/01/' target='_new'>Get Them Now</a></body>
