Midibox SID - Just intonation?

[Snoozr]

I've read through the manual a number of times but perhaps I've missed it. Is there any (relatively straightforward) way to get just intonated chords on the MB-SID family synths? I have a lot of fun with the harsh SID sounds but sometimes you want something sweet-sounding. Searched for "just chords" and "just intonation" but came up empty...

I'm not sure i understand correctly...

If you want to play chords, you can use the Multi engine. I'm pretty sure you knew this already though, and i'm just misunderstanding your question.

Maybe you can clarify a bit?

Sure. Most music for the past couple hundred years uses equal temperament for some very good physical reasons. But for electronic music where there are no physical strings etc., just temperament/intonation can be used. It makes for more stable chords that sound nicer in some places. What happens is that certain parts of a chord (usually the third and fifth) would be micro-tuned.

More info here: http://en.wikipedia.org/wiki/Just_intonation

and this audio example should make it more concrete

Sounds really great on guitars by the way...

You can adjust the frequency table (that should make for a great search term).

Ok thanks. I looked around in some of the OS .inc files but that was about as far as I got. I'll give it another go at some point.

The formula for calculating these numbers is well described in the SID datasheet
