Any word on pricing yet? Those banana ones are... tempting to say the least!

The production of the faceplates is killing him! Very hard to get someone decent to do this here in Rio (and even in São Paulo!).

Curiously, the main components are ready to go - he received the PCBs about months ago - stacks and stacks of them - I saw the piles myself, a small fortune in PCBs alone. Thus, with the boards and components at hand, he can finish a module in no time. But the problem is the printing - this has always been a tremendous headache.

The faceplates were to be delivered before December by the supplier - but from what I know, they weren't, which drove Vinicius up the wall. I recall that he was especially worried about fulfilling your order, which would suffer somewhat of a delay because of the faceplates. Since I last spoke to him, the supplier is finally sending the plates in a rather uneven flow.

Time in Rio marches very, very slow. As an example, I went out to order a case for the modules in the only place that does this in Rio, far out in a distant suburb of the city (not a very nice place to be; somewhat akin to the baraka market in Mogadishu...). Had to go back and forth for weeks on end so they could get this right (countless screw ups here and there) - something that was suppose to have been completed in 15 days from my initial order took over four months to receive (!!!!). During this time, aside from my order with Vinicius, I bought various modules from Analogue Haven, which have been lying in a box ever since. A real pain in the arse. But there's nothing I can do but wait. And this has worried me quite a bit - I am to move permanently to Curitiba in the next few months and hopefully all modules (i.e., my order and yours) will be mounted and ready to make some noise.

Vinicius is always very prompt and careful with what he does; a very decent and professional fellow - but, unfortunately, he depends on third parties who are a bit too lax with time, a rather scare commodity here, in Rio - a village that is still living in the past, full of slackers who horse around at every opportunity.


If the faceplates are a problem, maybe Vinicius could offer up the Frontpanel Express files so a buyer could get the faceplates made themselves. It seems like this would really help the delays. thumbs up

Really don't know mate, he is rushing like crazy to finish my system and be able to move his business foward and attend other people!!

In fact, appart from the modular syste, he's finishing an analog step sequencer for me called "Chronos 32".

It has 32 steps, with knobs for each step and up to 4 indenpendent simultaneous sequences. You also can save the sequences.

And after he finishes all that, I want his effects units! He got a killer phaser and chorus modules, can't wait to test them too!!

we're not worthy we're not worthy we're not worthy we're not worthy

I'm blown away by all of his options and offerings. Vinicius will be a major player coming to an analogue haven near you. Guinness ftw!

Guys, Vinicius just sent me some audio demos of the oscillators after final calibration, only to make me more anxious!!

Can't wait to make a lot of videos and demos for you all!

I was having a hard time trying to post an audio attachment here, so I uploaded to my soundcloud account. The download is enabled for the mp3 file, cause soundcloud compression fucks up the sound.

***note that these sounds are only from the oscillators, no filters or vcas used!! He only applied a tad of reverb and delay to wide things out!

Aether Oscillator file description:

First Sequence - Sine Wave (note sequence generated by a stepped positive saw waveform from the oscillator's LFO into the cv input)

Second sequece - SAW Wave output

Third sequence - TRIANGLE Wave output

Fourth sequence - PULSE WAve output, with PWM knob tweaking

Fifth sequence - SUB SQUARE Wave output

Sixth sequence - Aleatory note playing gradualy adding oscillators until all 4 oscillators are playing together at different intervals.

This time only 2 OSC!

FM demo, the sound you hear is the output of only one OSC!


Aether Oscillators FM file description:

First segment: OSC 1 (sine) OSC 2 (triangle) modulated by OSC1


Second segment: you hear the PULSE wave output of one oscillator being modulated by the other.

Me too!

I'm so impressed with the sound quality!

And this is not even scratching the surface of the system...

Each oscillator has outputs for each waveform, plus two SUB ouputs (1 octave below and the other 2 octaves below).

With only one oscillator and a mixer you can create a huge variety of sounds!! And each oscillator got it's own dedicated LFO, wich can be used for self modulation or system modulation.

One more demo, this time featuring the MultiPhaser module.

Note that it's a continuous note being fed into the input of the MultiPhaser, all the crazy modulations going on are made by this module.

Aether Oscillator into MultiPhaser:

Guitar into MultiPhaser:

Hey guys! I just got an email from Vinicius regarding the "hybrid" factor. Someone asked how his oscillators works, and a lot of people, when read the word "hybrid vco" or whatever, thinks that the sound is digitaly generated. This is not the case. (I'm gonna try my best to translate this, maybe this will make sense to electronic engineers and stuff, cause I don't understand jargons):

"All the modules are made using 100% discrete parts, with the exception of the Multi LFO's (2 lfos are 100% analog, 1 is hybrid), LIZARD (all 8 LFO's are 100% analog, the VCO is hybrid) and the Aether Oscillators. The S&H and Quantizer also uses digital parts, it's the only way to do it.

The Aether Oscillator is a extremely powerful hybrid VCO, it generates 6 simultaneous waveforms: SINE / SAW / TRIANGLE / PULSE / SUB1 / SUB2.

The SUB1 outputs a square wave 1 octave below the one being played, and the SUB2 2 octaves.

Each OSC has it's own dedicated LFO, wich generates 8 selectable waveforms: PositiveSaw / NegativeSaw / Sine / Triangle / Square / Stepped PositiveSaw / Stepped NegativeSaw / Stepped Triangle.

CV inputs are standard 0 - 10 volts / 1volt per octave

Aether Oscillator is a hybrid VCO.

Two major issues with 100% 1v/octave analog VCOs are the tuning instability and linearity. And those issues are not generated by the oscillator. They are generate by the linear/exponencial converter, basically made by a pair of transistors, using the exponencial transfer attribute of the ("base-emitter junction"???), wich is extremely temperature dependent. A lot of artifices are used to compensate this dependency. To avoid those deficiencies, the exponencial/linear conversor and time base of the Aether Oscillators are digital, but ALL the waveforms are analog generated.

The core of the oscillatores generates a protosaw, and from it, SAW and TRIANGLE are analog generated. The SINE wave is analog generated from the TRIANGLE.

Most of the modern synths have a frequency sample rate between 44.1kHz or 48kHz, and a few goes up to 96KHz.

For the real "analog experience", the real sample rate of the DSP (exponential/linear and time base core) is 500KHz!! 10 times more!!

As the dedicated LFO operates in the same manner, it's also digitaly implemented, allowing the generation of it's 8 waveforms."

I hope that elucidates the "hybrid" part...

Señor PointSource,

Sexta que vem vou baixar lá e checar isso tudo pessoalmente - ao vivo e a cores.

até, w.
