Dear Mike and Andrew,<br><br>Thank you for your speedy responses, though I think I am not explaining myself very well. I don't want to use mtof or ftom as these objects even out my ratios. What I'm looking to do is create a scale (say 12 notes for example) out of these ratio's with the possibility of filling in the consonant gaps whilst preserving the original frequencies and ratio's. The 1st number in each group is the strongest partial so: 912Hz, 1081Hz, 1211Hz etc. If I'm saying that these frequencies are 'good' to my ear, is there a way of creating equally 'good' sounding notes to fill in the gaps in, say for example, a 12 note scale based on these notes scaling from the lowest to the highest without doing the whole thing 'by ear'?<br>
<br>Cheers for weighing in,<br><br>Jbz<br><br><div class="gmail_quote">On Mon, Jul 20, 2009 at 11:16 PM, Andrew Faraday <span dir="ltr"><<a href="mailto:jbturgid@hotmail.com">jbturgid@hotmail.com</a>></span> wrote:<br>

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>

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>
