tid bit stumped on this patch behavior

2007-11-15 by josh

Aloha evolvorz,

been rocking the evolver desktop for a couple months now and
OH MAN i love this little thing!

I fell pretty comfortable for the most part finding my own way around
it, but I cannot figure out why this particular patch is behaving as
it is...

I have some guesses and I'll try to explain.

I've uploaded the patch to check out here:
http://tinyurl.com/2szj5h

OK 
first of all I started with a completely blank patch, built it myself,
and there's not any modulation (that I can think of or find) that
should be affecting the patch as it seems to be doing...

when set to SAT waveform (I only have osc 1&2 turned up & they're both
SAT) it seems like the very low notes only (mostly) come out of the
right channel. It kind of seems like either:

A) the keyfollow is modulating the pitch, or

B) the filter freq is set lower on the right channel (this one seems
more like what is happening but I can't see how...)

the wierd(er) thing is when I switch the waveforms on both OSC 1 &2 to
PUL 50 (aka square) it's not affected the same way- it behaves as I'd
expect; a slight variation in the left/right channels due to each
having their own analog filter applied.

the way the patch is set up, right and left channels are hard panned,
so I expect some variation in the filters of each channel, and when
the waveform is square it behaves as I'd expect. But when it's
sawtooth there is a distinct panning when you hit the lower notes. 

This isn't such a huge problem, and it really is maybe quite an
inconsequential thing that nobody cares about, but I really want to
know exactly what is happening here! 
I'm just a synth nerd who loves to understand the inner working of a
patch ;-)

Any die hard evolver vets out there willing to shed some light?

thanks!
josh -heckadecimal-

ps- if I can clarify any further or you're unable to get to the patch
just ask and I can either email it to you or possibly post to the file
area of this group KTHXBY
