That's the tricky part, right. The baseline of 'Ring Of Fire' is tuned one
octave down for example.
Then one note was still missing. I don't remember which it was, but what
I was doing (in priciple, these are _not_ the real values!) was this:
Assume that H3 was missing. I looked up H4 found it was +38 off tune.
I looked up H2, which was -2 off tune. Fine.
Let's say H2 had a frequency of ~45Hz. Then the missing H3 should have
~90 Hz. So I was looking for the value closest to the needed frequency,
which might have been some A#3 with 87Hz...
(I'm really no musician at all, but the end result sounded Ok
to me... :-))

There's one thing you might have overlooked, at least I'm not reading this
in your mails:
_You can't mix certain distortions!_
Let's assume you play a melody from distortion 4 with some almost perfect
notes only +- 5 cent off tune. Now even when in distortion 1 would
be the perfect last missing note with a +2 cent, you can't use it!
It's like mixing a sine with a sawtooth or rectangle wave.
As you see in the 'Ring Of Fire' distortion table, I mixed
mainly distortion 1 & 7 for the baseline and
distortion 4 & 12 for the melody, which sounded 'Ok' to me.
Actually I think
there's not too much variety you can bring in there.
You can use one set of distortions for melody notes
from ocatve 4-6 and one set for baseline notes ranging
from octave 1-3. The third, 'noise' distortion, can
be used for making some drumlike sounds...
So, the first thing one should do is categorize the distortions
by 'sinelike', 'sawtoothlike' & 'noise'.
Greetings,
Manuel
