I'm sure lots of folks have
figured it out already, but it wasn't till two years after buying a DM12
that I realised you could get pretty much any equal division of the
octave tuning out of it. Here's how: <br clear="none"></div><div><br clear="none"></div><div>You'll need two modulation slots. NoteNum->PitchCoarse and NoteNum->PitchFine.<br clear="none">
<br clear="none">
To solve for the coarse amount use (1536-128(TET))/TET</div><div><br clear="none"></div><div>You'll probably get something like -54.8571 (this is for 21TET).<br clear="none">
(BTW, it's negative because we need to reduce the key scaling down from
the hardwired 12TET amount. If you plugged in for 10TET, you'd get a
positive value.)</div><div><br clear="none"></div><div>
So, round that to -55 and plug it into your coarse amount. Now we get out our FineTune to trim the error away. <br clear="none"></div><div><br clear="none"></div><div>
Multiply the difference by 256. So that's 256*0.142857... giving us
36.5714. Round that to 37 and enter that into the NotNum->fine tune
amount.</div><div>
Note that this is a positive modulation amount because we rounded our
coarse down to 55, which made the spread a wee bit more than 21tet.<br clear="none">
Also you can just trim the fine amount by ear.<br clear="none">
<br clear="none">
Done!<br clear="none">
<br clear="none">
I believe this works for any TET up to 1536TET. <br clear="none"></div><div><br clear="none"></div><div><br clear="none">-- <br clear="none"><div dir="ltr"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><a shape="rect" href="https://www.instagram.com/colinmuirdorward/" rel="nofollow" target="_blank">https://www.instagram.com/colinmuirdorward/</a></div><div><a shape="rect" href="https://www.instagram.com/colinmuirdorward/" rel="nofollow" target="_blank">-<br clear="none"></a></div><div><a shape="rect" href="https://www.instagram.com/ssdp_synthesis/" rel="nofollow" target="_blank">https://www.instagram.com/ssdp_synthesis/</a></div></div></div></div></div></div></div></div></div>
