finally spent some time playing about with this module.
Building on the white noise patch, I seem to have stumbled across Cold Mac acting as an oscillator. In fact a little like the benjolin in some aspects- which having looked at this thread makes sense if it's half a triangle wave.
I was mucking about with building on the white noise patch (covered elsewhere), which was as follows:
Crease out to survey
monitor mac out
white noise when survey is turned at about 9.15 and 2.45
the patch for the oscillator is as follows (mdoudoroffs nomenclature):
Right out to crease
crease out to triat A
triat A to survey
Mac out to maths Ch 3
Maths sum out to left
monitor mac out via stackable
Ch 1 and 4 at 12
Ch 2 at 3o'clock
Ch 3 controls pitch between 12 and full CW
Survey know also controls the sound from 12o'clock to full CW
You can get some very unstable sounds out of it with a very subtle setting of Maths channel 3 just past 12o'clock.
Recording below - only have the ipad to record on at mo, so apologies for the quality.
