TABOR - Rhythmic Oscillator

hi wigglers!

TABØR is a rhythmic analogue sound source and envelope generator based on the unpredictability of four avalanche transistors in a continuous oscillation state.
These unpredictable core oscillators are related to each other and their charge and discharge cycle creates complex rhythmic textures that can be controlled and triggered with external CV inputs to add more contamination.

The principle behind the oscillators is the reverse avalanche effect.
With this circuit we can obtain rhythmic textures - intended as rise pulses - and different tone heights by mixing the colors of the LEDs and the values of the capacitors.

The waveform of a single oscillator, unfiltered, is basically a sawtooth. The result of the FM modulation of the whole sound engine is chaotic.

Features
Four avalanche oscillators with two controls each:
F: regulates the distance between the spikes of the single sawtooth waves - their rise pulses frequency
M: the amount of cross-modulation of each core within the others

Each oscillator can be identified thanks to its color and it can acts differently depending on the state of the others:
OSC1: the most percussive and predominant, the fundamental modulator
OSC2: obedient to OSC1 rhythmically and its direct subsidiary - a carrier
OSC3: strictly related to OSC2 but can set-aside OSC1 as a modulator
OSC4: it can act as a shutter to filter or interrupt the whole communication
these variables can all be controlled individually with vactrol CV inputs

Visually you can see the "beating" oscillators in the hollow circle in the middle of the module.

To start oscillate and communicate the sound engine needs around 16v to 22v and any value below that point will stop hierarchically its operation:
RM: this input act as an attenuator to the oscillators, limiting their power supply
A dummy cable will shut down the oscillators due to the inverted-vactrol configuration of this input. The RM input can be used as an internal voltage-controlled-attenuator, a VCA

The result of the whole sound engine is given in three different outputs:
TR: a “squarified” always positive 0-7v trigger / cv source
This output is not always active, it fires triggers when the avalanche engine reaches a certain threshold: blue LEDs blinking
NM: the dry mixed audio signal straight out of the oscillators
ZZ: an auxiliary fuzzed envelope output from the internal diode-based distortion circuit

pre-orders available for the first 50 assembled units / full kits

This is pretty neat, especially the huge orb in the middle. Can't tell, in the video is it making the tone as well as the clicking?

Instant war of the worlds (sounding and looking). Pretty cool.

Thanks!
In part II Tabør is used both as a modulator - NM out into the Befaco Even Vco - and as trigger generator - TR out into Mutant Bassdrum. The ZZ audio output is feed into uJove and then to the final stage of the mixer.

Here you can hear the raw sound:
(beware of the volume if you are using headphones)

Looks beautiful, description sounds interesting, video intriguing. But none of it really tells me much. More info needed.

I'll be happy to give all the informations that I can, what do you want to know about it? Since I'm forced at home because of the quarantine I have a lot of time to give answers and make other videos if needed :ghost:

Fantastic, thanks! So a few questions:
- Does it track 1v/oct ? If so can we hear it sequenced ?
- Are the oscillators always harmonically related?
- Is there a trigger or gate input?
- Does it accept clock input or is that not relevant ?
- What sort of modulation inputs work best ?
- Can we hear the effect of different sort of inputs ?
- Does it internally cross modulate the oscillators ?
- Can external audio input be a modulator ?
- Can we hear a comparison of the three outputs ?

Seems a fascinating module, so would love to hear more!

Perfect! I'll make a Q/A video tomorrow trying to answer all this questions. If there are more let me know! :bananallama:

very cool! nice to see something so different.
some of the sounds almost remind me of what i get out of my doepfer a 196 pll sometimes, but sill very unique!

Here it is. I'm sorry but it took me longer than expected. I'm not so good at editing and I'm still learning.
If there are more questions or something was not well explained I'll be happy to make another one.
Any suggestion is welcome

Great video! Thanks.
(Edit: I also only notice now you are based in Milan! Strength and heart and best wishes to you)

Appreciate the comprehensive look at the questions. I found the video strangely compelling even though, to be frank, the sounds in the first half seem to be mainly squeaks, clicks, birdsong and seasick animals. Of course all must respect an oscillator which decides when it would like to make a noise and if not fed material to its liking will simply shut down.

And then from 13:30 or so when you say "let it talk" - amazing audio ! :eek: I hear some light effects on the sound and you are giving it some modulation sources, but is the output still 100% Tabor ? Wonderfully complex layers and beautifully weird.

I admire your launch now in spite of all adversity. When are you expecting pre-orders to ship?

Thanks for the video, unfortunately you lost me at “doesn’t track v/octave” :party:

Thank you, we are just waiting home it to pass. It's a big deal for a lot of people.

Tabor is a quirky noisy beast, but it can be tamed and clocked

At the end there is some granular magic happening but the source is Tabor only

We need to work, if I can work from home I can still buy food at least :roll: We are preparing the kits and bulding the modules. Pre-orders will be ready to ship once this global mess ends. Here in Italy only primary needs goods can travel, and modules unfortunately are not primary goods :despair:
We need to wait 1 or 2 months

Whoa there, very cool, including the birdsong! Is the kit through hole? Since the manual talks about "horizontal orientation" of resistors...

I'm not sure what's going on, but, well ah crap..what now?

Thanks! Yes, the kit is all through hole. I'm gonna update the manual with some pictures this week
