Dear Mike and Andrew,<br><br>Thank you for your speedy responses, though I think I am not explaining myself very well.  I don&#39;t want to use mtof or ftom as these objects even out my ratios.  What I&#39;m looking to do is create a scale (say 12 notes for example) out of these ratio&#39;s with the possibility of filling in the consonant gaps whilst preserving the original frequencies and ratio&#39;s.  The 1st number in each group is the strongest partial so:  912Hz, 1081Hz,  1211Hz etc.  If I&#39;m saying that these frequencies are &#39;good&#39; to my ear, is there a way of creating equally &#39;good&#39; 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 &#39;by ear&#39;?<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">&lt;<a href="mailto:jbturgid@hotmail.com">jbturgid@hotmail.com</a>&gt;</span> wrote:<br>

Hey Jbz<div><br></div><div>I&#39;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&#39;s the effect you&#39;re after.</div>

<br>Here&#39;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>
