Fat Bastard's Tellun ' Neural Agonizer'

via Beermaster

"Thought I'd send you a couple of shots of the Tellun ' Neural Agonizer' that I've had made by Todd Fletcher - Check out the size of these reverb pans ! ! This is one of the latest additions to Fat Bastard - previously added a Tellun 'Doomsday Machine' too.

( Fat Bastard got a nice mention and pic in the new SOS Modular feature too )"

See these posts for more by beermaster including some shots of Fat Bastard. Note Fat Bastard is beermaster's uber modular and not an alias for someone. The modular has a bit of everything and is, um, FAT. If you haven't seen it, check it out.

JH Chorus/Vibrato/Scanner panel

via Scott of www.tellun.com on the ModularSynthPanels list:

"I've posted an image of my proposal for a combined chorus/vibrato/ scanner panel:

I wanted to get this to fit into 3U so I had to use small knobs and non-standard spacing, sorry. It's very similar to Dave Brown's panel; the 9 jacks/LEDs/pots along the left edge are on the same spacing as the UEG. I used a switch for the Celeste function, and both a switch and pot for Chorus/Vibrato control. The switch turns chorus on, and the pot sets the chorus depth. There was no room to add pots for the
input level and lowpass filter."

via neandrewthal on this electro-music.com thread where you will find more images:

"Here's what I did this year. Ok, I kinda cheated. I started last November, but due to delays I had the first module up and running in January.

Great big thanks to everyone who asked/answered questions and those who made these awesome projects available!

Module list: (left to right)

Bottom row:
PAIA midi2cv (never use it, think I'm gonna chuck it to make room for the appendage Cool ), MFOS VCLFO x2, MFOS dual VCA, MFOS VCO x2, MFOS noise cornucopia, CGS Psycho LFO, MFOS 24 db lowpass, MFOS multimode filter, Dual MFOS sample&hold, Dual MFOS ADSR, MFOS dual VCA.

Green = Audio input
Yellow = Audio output

Grey = Universal processing input
White = Universal output."
Note this is the modular in this video.

Still more Neural Agonizer antagonism.

"I think you can tell what my favorite module is by now.

I'm gonna start giving these videos different names, and you can just assume that the reverb is cranked up ;)

This one is a bit different, but the result is much the same. 2 VCO's and a wogglebug go through various filters and waveshapers before the Neural Agonizer. The mankato modulates several parameters in the patch 90 degrees apart.

If there's anything I've learned so far it's I NEED MORE LFO's and VCA's. The next cabinet is gonna have 16 of each."

TLN-865 Trigger Extractor & Window Comparator

"The TLN-865 Trigger Extractor & Window Comparator is an adaptation of a window comparator from Jung's Op-Amp Cookbook. This circuit can also function as a trigger extractor. A window comparator produces an output that is high if the input signal is greater than the lower threshold and less than the upper threshold. Otherwise the output is low. In other words:" see the full discription for more.

More Neural Agonizer action.

"Dense patch. Sparse sound. A single oscillator through the Neural Ag again."

Hot Tellun Neural Agonizer...

Youtube via neandrewthal

"First patch with the Neural Agonizer. Thought it would be fun to see what it could do to a single droning VCO. The 8 VC-able parameters are modulated by noise, LFOs, envelopes, S&Hs & Wogglebug. Mankato filter and PS-3100 resonators are in the 2 effects send paths. CGS sub-oscillator is in the feedback path."

TLN 428 VCF Kit

images via this auction

"kit for a TLN-428 Voltage Controlled State Variable Filter... Tellun synth projects are well documented and well designed. They are the closet thing to MOTM in synth DIY. Take a look at his website for more amazing projects.

Auction includes:
Tellun PCB - out of production / no longer available
Stooge mounting bracket
PCB Stand Offs
Jacks and Pots (Pots are Alpha and not the more exspensive Bourns or Spectrol. One of the Pots will need to have it's shaft cut tomatch the others)
All board mouted components including CEM 3320 (Which sell for $40.00!)
Black mounting screws (to mount your panel in to MOTM style rails)
IC Sockets
Wire - Including shielded audio for the
Solder - both organic and no clean
MOTM Power cable
Tellun User's Guide, and schematics - which can be found online here

You'll need to supply a small amount of heat shrink grease (Scrap some off that old CPU in the garage;)

EVERYTHING EXCEPT FOR FRONT PANEL AND KNOBS!

This was never offered as a kit (well not to my knowledge anyway). I put this together as a kit - That's to say that it's not a kit offered by Tellun Industries."

Panel for JH String Filter

via Scott of tellun.com on the ModularSynthPanels list:
"I've decided to add individual outputs for each of the bandpass filters. This adds an additional 40 jacks to the panel and requires 2.5U of width. I don't want to start making panels in multiples of 1/2 U, nor do I want to try to add an additional 2U and and try to make everything fit by squishing everything closer together. Instead I've added an additional 3U and added extra space between the three sections (jack field at the left, pot field in the middle, main controls on the right).

I've posted a couple of layouts of this 8U wide monster. The first puts the jack field in the standard MOTM grid. The second uses a staggered grid. I think I prefer the staggered grid.

string_filter_panel3.gif
string_filter_panel4.gif

I've got the PCBs all soldered together and tested. I'll be cutting the panel today (plastic prototype), then I'll need to hook up all those pots and jacks, that could take a while."

TLN-863 Max Min Generator

"The TLN-863 Max Min Generator is a MUUB implementation of a Linear Or/And Gate from Jung's Op-Amp Cookbook. This circuit is very similar to Ken Stone's Analog Logic circuit and Dave Brown's Analogic circuit. With the MODE switch set to the MAX position, the output will be the maximum of inputs 1-3 (Linear Or). With the MODE switch set to the MIN position, the output will be the minimum of inputs 1-3 (Linear And). The THRESHOLD pot sets a voltage that is normalled to the input jacks when no signal is plugged into the jacks. This turns the circuit into a "Clipper" when the MODE switch is set to MIN (output voltage will not go below the THRESHOLD), and a "Clamper" when the MODE switch is set to MAX (output voltage will not exceed the THRESHOLD).
The TLN-863 pictured at left features two independent channels (A & B) with the following controls:

* THRESHOLD A/B: sets the voltage threshold for the Clipper/Clamper feature.
* MODE A/B: sets the operational mode to Min/And/Clipper or Max/Or/Clamper.

Note that the panel layout for this module (and the rest of my MUUB utility modules) uses the smaller type of knob found on Encore Electronic's UEG and Frequency Shifter. Most people will probably hate this, but I wanted to get the most functionality in the least amount of space while still maintaining some semblance to the MOTM standard. To this end, all of my MUUB utility modules use a new layout grid that allows up to 6 pots with 4 jacks, or 4 pots with 8 jacks, on a 1U wide module.

The TLN-863 Max Min Generator can be built using MUUB daughterboards.

Total current draw for TLN-863 is 17 mA @+15V and 17 mA @-15V."

The Alison Project Update

I posted about The Alison Project back on July 18 of 2006 and again on March 27 of 2007. Magnus wrote in to let me know the modular has grown to a gargantuan size as you can see in this image. Check out the gallery for more.

Update via The Alison Project in the comments: "The modular is mostly DIY, there are 8 Modcan modules now (order just arrived) and 1 Encore Freq Shift that I did not build. Rest are from various Manufacturer's and designers: MOTM (16 bought as kits), Blacet (kits), CGS, oakley, MFOS, J. Hiable, S. Stites, T. Henry, G. Richter, Tellun, Dave Brown, Paparelli and Yusynth."

TLN-156 Neural Agonizer

"The TLN-156 Neural Agonizer is a voltage controlled spring reverb processor. Although this module can be used to simulate room reverb with most audio signals, it includes numerous enhancements specifically designed for interfacing to a modular synthesizer. If you're looking for a smooth, natural sounding reverb system to make your synthesizer sound like its being played in the Concertgebouw, then go buy a Lexicon. This is not your grandmother's reverb tank, this is a noxious tool capable of inflicting some serious damage to your audio.

The TLN-156 features: an amplifier for controlling the input signal level, two reverb tanks that can be driven in series or parallel, separate recovery amplifiers and resonators for each reverb tank, a feedback amplifier with lowpass filter, and a deformation processor for combining the reverb tank outputs. Most parameters are voltage controllable and several patch points are available for adding additional signal processing. All inputs and outputs handle 10 Vpp audio signals and 5 volt control voltage signals (modular standard).

Total current draw for TLN-156 is 70 mA @+15V and 70 mA @-15V." [link]

Tellun Doomsday Machine front

flickr by sduck409 (click for more including some of the inside).

"The TLN-712 Doomsday Machine is a voltage controlled waveform animator for modular synthesizers. Originally conceived as two separate modules, the TLN-712 comprises two different animation circuits and four voltage-controlled LFOs (low frequency oscillators). The first animator (Thalaran Radiation Emitter) is based on the Multi-Phase Waveform Animator by Bernie Hutchins. The second animator (Cascading Biogenic Pulse) is based on the Pulse Width Multiplier by Craig Anderton. Both animators have been combined into one module along with four LFOs to create a self contained system that makes optimal use of panel space. All you need to add is a single oscillator and a few patch cords to create a marvelous mayhem of sonic madness. Add a second oscillator and you'll never get a date to the prom."

"What is your current favorite piece of hardware?
My Synthesizers.com /MOTM / Blacet /Tellun /Wiard /CGS /Oakley /Bananalogue Analogue Modular Synthesizer is my favorite (almost my *only*) piece of hardware. People talk a lot about the versatility of an analogue modular environment, but coming from computers and (particularly) MAX/MSP, I find modulars *fairly* limiting ... it's kind of the lowest amount of customizability that I find acceptable in hardware. I can't really see myself buying any synthesizers with fixed-signal paths, except for ones that I think are fairly unique in their sound/approach (i.e. Yamaha FSLR, Oberheim OBXM, etc. ) What's really astounding about all this analogue gear is who phenomenal it sounds."

banana frac

Click here for more shots. Note this is for sale via david[AT]davidrothbaum.com

WIARD:
1) noise ring (the chance input jack does not work as designed. since this was one of my first banana conversions i was unsure of how to deal with switching jacks! and so since the chance input is/was switching i simply did not convert it properly and it is just connected to the main output, which of course is totally silly. the proper conversion can be done by rewiring it with a switch as i did on quite a few modules after this one. I just never got around to completing this one).
2) boogie filter
3) borg filter

BLACET:
4) oscillator
5) oscillator
6) time machine
7) quad vca
(this one is probably the funkiest. First of all the main output has been converted to a 1/4" jack. secondly none of the CV jacks are connected and the alt output had been changed to work as a banana to 1/8" converter. So this module now functions as a basic 4 to1 mixer with gain on the 4th channel).
8) micro lfo
(the rate & gate inputs as well as the two outputs at the bottom left of the
module were not converted to banana jacks -- this is because the plugs are mounted to
the boards)

MOTM:
9) ladder filter

BANANALOGUE
10) 3-P

TELLUN:
11) neural agonizer (this is a custom built module i built myself. The panel i designed using front panel express to fit the frac format. there were a few switching jacks that i did not convert for the sake of simplicity. as with the noise ring, one could add switches to these to make them banana if you want to. Another important thing with this module is that the boards were designed to work with a MOTM sized system so they are quite large (there are two for this module). and so the way i did it was to NOT mount the boards to the panel at all but simply screw it to the bottom of the case. You can do this to one of the Blacet frac racks if you want using standoffs which is how i did it before i made the wood case. The module uses the two very large 3 spring accutronics reverb tanks that are mounted on the back of the case.
