Watch out! I just nuked 1-post user "gear101" after receiving five different complaints over the course of about 20mins that he's sending PMs to people offering to sell gear. Seems pretty fishy! I'm sure he'll be back under a different name but with the same old game. Be careful! Thanks to everyone who let me know about this guy.

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...

Two very disturbed oscillators:

Señor PointSource,

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

até, w.

Now presenting some LIZARD demos!!!!! Rockin' Banana! It's motherfucking bacon yo Rockin' Banana!

1st demo:

[s]http://soundcloud.com/point-source/lizard-seq-mode-level[/s]

1st segment:

LIZARD module in SEQUENCER + LEVEL mode (8 steps) modulating only one Aether Oscillator (via CV input) outputing a triangle wave.

2nd segment:

LIZARD module in SEQUENCER + LEVEL mode, but this time modulating the oscillator thru it's FM input. MIDI2CV output into OSC CV input, thus LIZARD is working as arpeggiator!!


2nd demo:

[s]http://soundcloud.com/point-source/lizard-seq-mode-lfos[/s]

LIZARD on SEQUENCER (8 steps) + LFO mode =Lizard's master output going into the CV input of only one Aether Oscillator, with some random knob adjustments.

1st segment: TRIANGLE wave

2nd segment: PULSE wave


3rd demo:

[s]http://soundcloud.com/point-source/lizard-vco-mode-wave[/s]

The true power of the LIZARD!

VCO mode + WAVE!!

1st segment:

SINE wave ouput of Aether Oscillator fed into WAVE1 input of Lizard, with some manual freq knob adustments. Lots of crazy timbres.

2nd segment:

Two more Aether Oscillators are fed into WAVE2 and WAVE3 inputs, also SINE waves.

Can you imagine using PULSE and SAW waves????

Tentar-lo-ei.

cheers, w.

(Did you receive my PMs? Did you get my e-mail? Drop me a line, B.!)

LOW PASS FILTER DEMOS: w00t

Aether Oscillator fed into LPF, with some freq and ressonance knob tweaking. This example showcase a bit of the ADSR generator as well.

[s]http://soundcloud.com/point-source/low-pass-filter-by-vbrazil[/s]


Self Oscillating LPF, ressonance at maximum, generating a pure sine wave.

[s]http://soundcloud.com/point-source/self-oscillating-lpf[/s]


Subtle difference between the 12 - 18 and 24 db outputs:

Lizard modulating the LPF cutoff and Aether OSC:

Some percussive sounds:

STATE VARIABLE FILTER nanners

Aether pulse output into State VCF, first HP, second LP and then BP.

Some ressonance tweaking.
