New Teia Synthesizers Eurorack Modular Maker - Stochastic Function Generator

Published on Feb 12, 2014 teia synthesizers·1 video

"The Stochastic Function Generator is the first Eurorack module design by TEIA Synthesizers."

"The production of the first batch has already started, hopefully this will be ready by the end of february!

Features overview:
-Random Rise and Fall determined by Maximum and Minimum knobs.
-Maximum knob value below the Minimum knob value module works as regular envelope generator.
-Switchable between Gate and Trigger.
-Loop mode(LFO mode).
-Gate Out proportional to the length of the Rise portion of the envelope.
- Inverter and attenuater control knob.
-Extra Bipolar output.
- Three speed modes, High , Mid and Low. Jumpers to change speed modes from Low to Super Low mode and High to Super High

Expansion Features:
Cv control over All Maximum and Minimum settings.
Gate input to activate/ deactivate loop mode.
CV output with the resulting random voltage value from the Rise and Fall knob settings.

All the best,
Ruben"

Hi all!
I present you the Stochastic Function Generator!
I want to show you guys something i've been working on for some time now, it's still not yet finished but i feel like is already worth showing.

So, the basic concept is, every time you feed a gate/trigger to the "Gate in" input the module randomizes a Rise(Attack) and Fall(Decay) value between the minimum and maximum knob settings. It has multiple uses, from playing subtle swing variations to crazy envelope shapes.

Setting the Maximum knob value below the Minimum knob value will cancel the stochastic process and it will work as a regular Attack and Decay envelope.

This is an hybrid circuit, this means the Function Generator (AKA Envelope Generator) core is analog and there is also a microcontroller to spice things up.

More:
- Switchable between Gate and Trigger.
- The Loop switch will re-trigger the envelope at the end of it's cycle.
- 3 speed modes, High , Mid and Low.
- There are two jumpers on the back to change speed modes from "low" to "super low" mode and "High" to "Super High".
- The "Gate Out" is a gate signal with the same length as the Attack portion of the envelope. This only works on trigger mode.(Useful to get random gates when loop mode is set)
- Manual trigger/gate push button
- The middle knob is an inverter and attenuater knob of the output signal.

At the moment there is also a simultaneous inverted output, but i'm considering changing it to a bipolar output, in my opinion this would be more useful to use it as a weird LFO in loop mode. What you guys thing?

Right now i'm re-doing the panel layout and i'll upload some videos/sound samples when i'm done with the new panel.

I might consider doing a small run (10 or so) if there is enough interest.

Coments, questions, suggestions and improvements are appreciated! please be kind thumbs up

Regards,
Ruben"
