VS-1 Polyphonic Analog Synthesizer

Unread post by Eduardo Rojas »

VCO's Two discrete VCO's per voice with saw and pulse waves. Pulse width can be adjusted from 0% to 100%. VCO1 can be modulated by VCO2 (crossmod) and VCO2 can by hard-synced to the frequency of VCO1. VCO's can also be modulated by two analog LFO's, two digital LFO's per-voice, and a DADSR 5-stage envelope generator.

Noise Analog white & pink noise.

Portamento Analog polyphonic portamento gives a natural clustering effect between voices as the analog components are never perfectly matched. Although this requires many additional components it has been included - another example of small imperfections that impart character. In addition, digital portamento with both fixed rate and fixed time modes is also included.

12dB OTA Filter The classic resonant 12dB multimode filter is the desert island filter, simply awesome in a polyphonic synth. The classic OB-X had a fixed lowpass mode, the OB-R has lowpass, bandpass & highpass modes.

Panning VCA's Each voice retains the classic 3080 OTA VCA but also includes a stereo panning VCA that can be modulated by several sources. The spread control make it easy to pan voices across the stereo field.

Envelope Generators Each voice has a dedicated analog ADSR for the filter and VCA. In addition there is a global five-stage DADSR with (20) modulation destinations.

Analog LFO's Two global analog LFO's with triangle, square and S&H waveforms can be sent to VCO1 frequency and pulse width, VCO2 frequency and pulse width, and filter cutoff.

Digital LFO’s Two LFO’s per voice with triangle, sawtooth, reverse sawtooth, square, and random waves with (20) destinations. LFO’s also have dedicated attack-decay envelopes and can be free-running or synced to the arpeggiator, sequencer, or MIDI clock for tempo-synced effects.

I wasn't sure what this was meant to be from your post (apart from an analog of course), so did some quick research

Looks like it is modelled after the Oberheim OB-X.

They are running a kick starter campaign to fund it.

Looks like it will cost you $995 for an eight voice in kit form, and different pledges will get you different variants in built form but the retail 8 voices is $3,995

TBH, like Deckard's Dream (CS80 clone) before it, there is nothing in the sound demos that make me go "wow, I must spend that sort of money". The Rush Subdivsions sound demo, caught my ear the most, as I love that song (and have been having a Rush day in memory of the mighty Neil Peart), however they have not got anywhere near close to the studio sound (theirs is way to fizzy) and I have heard a better version coming out of the Kronos AL-1 engine.

I think I will stick with my OPX-PRO and Arturia Matrix 12 VSTs for my Obie sounds. :)
