Tube module DIY

Post by QuantumMechanakillWave » Sun Aug 23, 2020 7:07 pm

Ok. Headphones recommended for this content, but watch the levels! :wink:

Is it distortion? Wave folding? Phaser? Yes. Why choose? This circuit uses morphological gain staging techniques to create a blob of an analog circuit that has the properties of distortion, phaser and wavefolding circuits. It has four voltage controllable parameters: Input Level, Morphology, Wet/Dry Mix and Output Level. In this video, I am showing off some of the wave folding possibilities by modulating input level with Maths. Towards the end, I adjust the Morphology control to show the interactivity of the parameters. Among other parts, this design uses an ECC83, 12AT7, and a couple of vactrols. I have included some sound samples below the video:



Here is a sound demo of the circuit processing a Moog Grandmother. The demo starts out dry and then fades to wet. ONLY the Morphology parameter is being modulated throughout the recording. No changes are being made to the Grandmother:


Here it processing a drum track:


Here it is processing the filter of the Grandmother tracking as a sine wave oscillator going into the spring reverb and then into the circuit:

Great tones! Will you publish the circuit?

Thank you! I have yet to decide on that. If I do it will not be for a while.

Very interesting noise.

Does it really need tubes, or could the same effect be done solid state?

I’ve done a few different solid state versions. While they were interesting, they did not have the dimension, punch or character of this circuit. This version is also the best at reproducing the low frequencies. Excellent compression and surprisingly good noise characteristics even with my shitty breadboard routing skills.

What plate voltages are you using for the tubes?

Bravo! I've listened to all of the files more than once. I think that this sounds lovely and it appears to be rather useable with more than one shade of alteration to the core tone.
I'd love to see this in a Buchla ModuleModule format or a DIY Eurorack thing.

Bravo and well done!

I like it a lot. Interesting tones. Hope this project goes public in some form 🙂

Wow, that is ‘starved plate’ taken to extreme.
