Moog 700 drums & percussion and Minimoog - #4

Published on Apr 25, 2017 noddyspuncture

"Here once again, I've sync'd the home brew sequencer I built for the Moog drums to the clock on the Q960 sequencer. All four 700 series modules are used in this one along with the Minimoog... and you can't beat a *real* Minimoog. Don't ever let anyone tell you any different...!"

3 Modules #4: Clouds, Ears, Ripples

Published on Apr 25, 2017 Comparative Irrelevance

All parts here.

"Wow, this one turned out to be a lot of fun! As you can hear, this patch is capable of a wide range of craziness – all without using any "support" modules, and without any added reverb or other out-of-the-rack effects. (show more)

I figured the "obvious" way to go here, would be to use Ears' contact mic as a sound source, filter the audio through Ripples, and tag on the Clouds as a delay/reverb effect at the end. So, naturally, I decided to do something completely different. :)

Patch notes:
This is basically a feedback loop, from Clouds' output via Ears, through Ripples' 4 pole LPF, and back into Clouds. For most of the patch, though, Ripples' resonance is at full, which means it produces sine tones – the audio input is virtually inaudible at max resonance.

However, by using Ears' envelope follower output to control the gain on Ripples, there's still a feedback response, even when the audio input is drowned by the resonance peak. I think it's easy to forget that Ears is more than just a contact mic/external audio input. Its envelope follower and gate makes it ideally suited to control feedback loops in this manner.

The sine tones/fed back audio is passed from Ripples to Clouds, which chops it up into grains, pitch shifts those grains, and adds reverb. I'm manually modulating the grain size, density, texture (i.e. grain envelope shape) and reverb mix level. The pitch is modulated with an audio signal from Ripples BP2 output. However, since the pitch is set "per grain", the result is more akin to a S&H pitch modulation than audio rate FM.

Thanks for watching!

3 Modules #2: uScale, Brain Seed, Branches

Published on Apr 17, 2017 Comparative Irrelevance

"This is probably the silliest three module combination I can put together: none of these modules produce any kind of signal on their own, and even with external input they're not really meant to produce sound. (Patch notes below)

Patch #1:
Noise tools generates an audio rate pulse wave, which feeds into Branches. Branches produces two signals from this input: a pulse wave at an octave below the input (ch. 1) and a sporadic series of triggers (ch. 2).

The pulse wave is then fed into the slew limter, as a basic low pass filter to smooth it out a little. It then passes to the uScale V/oct, which functions as a kind of bit crusher (disabling steps leads to a lower "bit depth"). The output from uScale is the audio signal we hear.

The triggers from Branches are used to step through a sequence of random values on the Brain Seed. These values are then sent to the uScale shift input, which causes the audio signal to sputter and jump around to different pitches and tones.

Patch #2:
I actually made this one first, but it felt a bit "cheaty" because of the heavy use of the shimmer reverb and filtering via the noise tools slew limiter, and also the uScale didn't really contribute much. Anyways, here's what's up:

Once again, the noise tools provides an audio rate pulse wave. Branches and Brain Seed are used to divide the signal into different sub-harmonics, and uScale is used to bitcrush one of the waves.

These three drones are mixed together in the Quadratt, which is what I'm tweaking most of the time, and then the sum is sent through the slew limiter/LPF on its way out to the Big Sky reverb."
