Ah the new thread is up - happy new thread Exclamation

It'd flange with the proper modulation .. but .. what is the twist?

With the slow changes used in the demo it's like Karplus Strong Cool

The twist is that I use an attenuverter to control the feedback.

Is that a 3d printed panel? How well does that work?

Yes, it’s 3D printed and it is working really well,
First I start printing the panel and as soon as the printer starts to print the characters which are about 1.5 mm high, I pause the printer, change the filament to another color and resume printing. So you need to keep an eye on the printing progress.
I learned that 3mm thick panels is a good thickness but also that it needs more than one attachment screw for top and bottom fixture because else it would bend too much when plugs are pulled from the panel.

yeah I think you're going to need a bigger case alan Shocked


here's a circuit bend video switcher (V-Guard VA-203) for some CV controlled glitchyness and it has 2 build in LFO's to use instead of a CV. shakng2

Turing Machine (MKII) with integrated Volts and Pulses expanders and a few mods.

Be interesting to compare this with the CGS Infinite Melody and the Klee.

(For some reason, the images have been rotated in posting...)

Thanks, yes it's an image of the side of a shipwreck; wooden knobs when I get round to making them complete the look.

Slightly off topic, but I did a comparison of various sequencing modules as I suggested above, and here is the audio file.

Just a sawtooth driven by the CV output of each module in turn, after passing through a quantiser, with a simple envelope.

0-1min is the Klee in 8 step and Random mode with white noise as the random source.
1-2min is the Turing Machine in 8 step fully random mode, then from 2-3.5min I adjust the mode knob slowly towards lock - in the intermediate positions the sequence changes progessively less frequently.
3.5-4.5 min is the Infinite Melody in Random mode
4.5-5.5 min is the Infinite Melody in 1/f mode.

They all of course have lots of other features that distinguish them and make them all useful, but to my ears, the Klee is very random, the Turing Machine exhibits more runs on notes, and the Infinite Melody in 1/f is the most melodic with more passages.

Waveform Animator, based on the ETI waveform multiplier, with a number of mods:
Dual unit: two separate animator sections, driven by a single set of modulating LFOs;
Input Type control, permitting use of either 0-10V inputs or +/-5V inputs;
Modulation section provides six animating waveforms, in two banks of three (Mod#1-3 and Mod#4-6), with four-way Modulation Speed switches for each bank to select between Slowest, Slow, Normal and Fast;
Mod#1 can also be switched to an External source;
Outputs modulated by subsets of the modulators: Mod#1 only, Mod#1-3, Mod#4-6 and All Mods.

Nice for beefing up a single oscillator, or two oscilators tuned a fifth apart.
