Sup Wigglers??

This month my modular system will be ready! I got these pics from Vinicius, wich is the engineer behind VBrazil Systems! I'm gonna be posting here a lot of videos and demos for you guys, all in Full HD. His modules will be available soon, in 3,5mm and banana jack formats.

Aether Oscillator:

Each oscillator has it's own dedicated LFO with 8 waveforms. More infos soon (he's gonna make manuals for each module, then I'll translate for you guys).

LIZARD:

Lizard is a unique module. It's a morphing LFO. It can be used as a complex oscillator (when feeding aether oscillators thru it's inputs). It can be used as a "analog wavetable", you can "program" waveforms using the LFO knobs. It can be used as a step sequencer. This think is really a crazy creation, a little beast! I believe it will take some time for me to master it! I already have it's "quick start manual", I'll try my best to translate for you guys.

MULTI LFO:

It has a S&H knob that modulate the waveforms, also has a NOISE output. I have it's "quick star manual", gonna be translating for you guys soon.

SAMPLE & HOLD / QUANTIZER:

More infos soon.

RING MODULATOR:

More infos soon.

MIDI2CV:

More infos soon.

DUAL 4 INPUTS MIXER:

FORMAT CONVERTER:

Still missing the filters and ADSR modules pics. Gonna be updating this thread constantly with more info about the gear. Stay tuned!

Wow, that's a pretty big way to enter the market, full system all at once. Looks good thumbs up

BTW, the Aether Oscillator image is broken.

LIZARD by Vbrazil systems

Introduction:

We can say that LIZARD is made of various modules integrated into one. It has a hybrid high performance VCO with several operation modes plus 8 VCLFO's totally analog.

VCLFO's:

LIZARD has 8 totally indenpendent VCLFO's. Each LFO has a signal output and a CV input for frequency control. It has a potenciometer to control the frequency and another one to control wave symmetry, allowing you to choose from negative saw to positive saw, passing thru triangle. Check the pics below:

The frequency of the LFO's goes from 0,01Hz (100 seconds) to 10Hz (0,1 seconds) when they are controlled using only the frequency potenciometers.

VCO LIZARD:

The sweeping oscillator is a high performance hybrid oscillator (analog/digital). It commands an analog selector wich "chooses" wich signal will be presented at the OUTPUT jack.

It has several modes/configurations of operation. The first configuration dictates how many STEPS it will work (4 or 8).

The second configuration dictates the source to be selected: LEVEL or LFO.

In LEVEL mode you can "draw" the waveform of the VCO using the LEVEL potenciometers, located above each LFO. This waveshape can have 4 or 8 segments, depending of how many STEPS you've chosen. Depending of the waveform that you've drew, the harmonic distribution varies radically, allowing a literally infinite number of timbres. The waveforms below were created using 8 STEPS:

In LFO mode, each LFO starts to be "sampled" in real time at it's respective step, creating a extremely rich "morphing wave" wich the sound cicle will be determined by the configuration of frequencies and symmetries of the LFO's, and it may take hours to change back to the same shape!!!

In this configuration, the LEVEL potenciometers will control the "participation" of each LFO in the "morphing wave". If 8 STEPS are chosen, all LFO's will be "sampled", and if 4 STEPS, only LFO's from 1 to 4 will be used, leaving LFO's 5 to 8 free to use in the modular system. And this doesn't neutralize the possibility to use the individual outputs of LFO's 1 to 4 in another aplications!!!!

SEQ / VCO mode:

The SEQ/VCO switch alters the frequency range of the main VCO, allowing to use it as a VCO (from 5Hz to 10KHz) or an analog step sequencer of 4 or 8 steps (20 seconds at 120Hz). If LEVEL mode is chosen, the CV's for each step are programmed by the LEVEL potenciometers. If LFO mode is chosen, the signal of each LFO will be presented at it's output at every step (check pic below):

WAVE mode

In WAVE mode, the first 4 steps will sample the signals presented at WAVE (1 to 4) inputs. If VCO mode is chosen, and you are feeding the wave inputs with a external VCO (aether oscillator for instance), the sonic possibilities are endless.

If SEQ mode is chosen, you can "lock" four external sequencers.

These are the VCO controls:

FREQ - frequency adjustment

FINE - fine frequency adjustment

FM - depth of frequency modulation

Inputs:

FM - frequency modulation (1V/oct)

CV - standard control voltage (1V/oct) 0~10Volts

HSYNC - hard sync

WAVE 1 to 4 - signal inputs

Ouputs:

OUTPUT - analog selector signal output

SQUARE - square ouput at the VCO frequency

Energy Consumption:

120mA @ +12volts / 60mA @ -12volts

Dimensions: Eurorack 57 HP (128,5mm x 289mm)

Here it's his website but i think it's still under construction. Anyway, haven't heard from Vinicius for a while and am really happy to see his new modules. I'm going to take an order as soon as he's ready.

Edit: better with the link

MULTI LFO by VBrazil Systems

MultiLFO is a module composed of three LFO's (Voltage Controlled Low Frequency Oscillators).

LFO 2 and LFO3 are exactly the same and 100% analog. Each one got it's own CV input for modulation and a potenciometer for local control. The CV input has a Width potenciometer to control the depth of CV modulation. This way you can modulate one with another and a lot of other things. They also have a SYM knob to control the symmetry of the waveform, varying from negative saw to positive, passing thru triangle. They also have a SQUARE output, wich is also affected by the symmetry knob, varying from a extremely narrow positive pulse to a negative pulse, very handy as a sync signal.

LFO 1

LFO 1 is an extremely powerful hybrid (analog/digital) LFO with 8 selectable waveforms, CV input, potenciometers, HSYNC input (with it's own characteristics), the main output and a NOISE output (with a peculiar distribution).

The controls are:

FREQ - LFO frequency

WAVEFORM - switches between the 8 waveforms - POSITIVE SAW, NEGATIVE SAW, SQUARE, TRIANGLE, SINE, EXPONENTIAL, SPIKE, NOISE (with a different frequency distribution than the indenpendent noise output)

PHASE

The phase knob distorts all the waveforms pictured above (except noise), in the speed wich 50% of the wave proceeds. This way, for instance, if you choose a triangle wave, the phase knob will act like LFO's 1 and 2 SYM knob. Check the pic below to understand better this phase distortion (first line SINE, second line NEGATIVE SAW and third line TRIANGLE):

S&H RATE

LFO 1 got it's own Sample & Hold. This potenciometer controls the S&H frequency. When set to zero (full anti-clockwise), S&H is turned off. When used in the noise waveform, it generates a random sequence. When used in the other waveforms, it generates "stepped" waveforms, check below:

CV WIDTH - controls the depth of CV modulation

SYNC MODE - this is a handy control. It dictates if the HSYNC input is ignored, if it affects only the LFO or the S&H or both!!! If you want to sync the S&H with a external clock, you only need to set the S&H rate slower than the external clock and that's it!! External sync to S&H! T

More infos soon!! The manual is incomplete, i think theres a few more tricks.

Nice lookin modules..... and that Lizard is woah

Are these going to be sold thru a US distributor?(AH, BigCity, etc...) ???

blz · Posted: Sun Jan 15, 2012 5:43 pm Post subject:

yeah the lizard looks like the sex MY ASS IS BLEEDING

perhaps a ballpark price on that fine item?

and am i correct in thinking the lfo can pull off analog shift register style cv

Greetings,

I'm the original instigator behind this.

I'm originally a guitarist (in real life, I'm a bureaucrat, who spends his days stamping things; but in my youth, about two decades or so ago, played in various post-punk and avant garde bands, making the most horrible noise) who, recently, became curious about the bunch of wires and patches and all things analogue, which I still am attempting to come to grips with, but seems terribly fun.

Vinicius, the madcap behind these slick black panels, I got to know a few years ago. He said he could build a basic system if I could come up with the initial $$$, which I did. And as for the last two years, he has been working his sorry arse off creating these eurorack modules (at the moment, unfortunately, there will be only Euro) from the darkness of his lab, located in the outskirts of Rio. He's quite excited by this, having received a few commissions for individual modules and, recently, for any entire system (I believe it was by our fine member, from Porto Alegre, who has kindly opened this thread). Although I'm far from an expert, I can guarantee all here that the PCBs he has designed are incredibly well-built, carefully crafted, using the best he can import and find (thus, as probably noticed, these are far from cheap little toys; all crated by hand, piece-by-piece, with hours and hours pondering about the design and concept of each module). Vinicius is a very experienced engineer and who has been working with audio for over 30 years; he has been brewing modules and analogue synths since the mid 70s. In sum, he not only knows his ball game, but excells in it. Brilliant fellow, amazing really.

At the present, I'm putting these modules together with some of the more popular stuff I can get my hands on (have a few well-known modules by Doepfer, WMD, Tip Top Audio and got a Maths and a Phonogene - have my eye, currently, on a few things by 4MS) and when ready, hopefully be able to scare all my neighbors....

As for sales in the US, Vinicius will only send these abroad after tested and re-tested. But, hopefully, they will hit Analogue Haven sometime this year. We're still seeing how to do this. And do this at competitive and decent prices.

Would like to thank everyone for their enthusiasm, especially to PointSource for opening this thread, and comments are more than welcome! Please don't feel coil to criticize or comment on the units.

cheers, w., the city of san sebastian.
