I was playing around with this patch more yesterday, and there are a number of possible variations to being able to sequence. One of the most wild was to put three sisters into the feedback loop between the Mac out and left input (instead of maths). You can then use different outputs from the three sisters to go into the left and right inputs for cold Mac. Add some self patched fm in three sisters, and you can start getting some very mad sounds. Sequencing can be done by the three sisters 1v/8 input (though I didn’t manage to try this with a sequencer per se, but used a quantised shift register output from the disting).
Nice idea. I found that modulating Fade had a nice subtle wave shaping affect.
You inspired me to try and make a Wavefolder with cold mac
CV in -> Fade In
Audio IN -> Left In
Right Out -> Crease In
AND Out -> Offset
Crease Out -> Slope In
Slope Out -> Audio Output
Moving survey from 0 to 12 o clock will affect the nature of the fold. Alternatively you can send an external DC offset into Offset In to get greater range. Fade in alters the amplitude of the wave before the folding occurs.
Modulation to both Survey and Fade sounds pretty cool, especially when approaching audio rate
In this video Fade In is being modulated by an LFO and I’m slowly moving Survey from 0 - 12 o clock
Hm, I think I found some sort of oscillation going on, but I just wanted to check my results against y’alls. I have:
OR out > CREASE in
MAC > OR1 in
MAC (mult) > listen
I get the highest pitches about 10:30 and then it bottoms out about to clicks at noon.
Then!
If you re-patch
AND out > CREASE in
and MAC > AND1 in
You get a lower pitch base starting about 12:30 to full CW. With some really interesting mechanical clicks. Putting stuff into AND2 gets you some pitch/timbral changes. And there’s even more noisy goodness if you patch CREASE out > SURVEY!
also using the 2nd inputs of OR and AND gives you half-wave rectification in the positive or negative direction. This way you can apply different transformations to either half of a waveform…
Pretty sure you’re right this I’m afraid. The other thing is that it doesn’t perfectly replicate the original voltage so it’s not good for portamento type pitch work if that’s the kind of thing you were thinking of?
Heaps of low end! And while I was patching it up I came across a version that changed the pulse width depending on the frequency so it had a bit of a thinning hipass vibe. Very cool!
