Lassence µVentury II Analog Synthesizer

   0 reviews  -  654 views

    The Ventury II Analog synthesizer is based around Lassence modules synthesizer, compact Solid state building blocks providing accurate and highly creative synthesizer functions. The modules present in the Ventury II have been chosen amongst a vast library of special functions so has to build a comprehensive, flexible and powerful, portable true analog synthesizer.Altough, all the modules are fixed to one front panel, the system is totally modular ; each module stands alone.

    We have endeavored to use the best analogue parts (no custom chips !), finest panel controls available : pots are cermet or conductive plastic (Sfernice, Bourns), switches and jacks are highly reliable (Marushin, Switchcraft). The system internal construction is clean and neat.

    The synthesizer is housed in a metal case which fits exactly into the black briefcase. It can easily pulled out of the briefcase again without any modifications.


    Generators : VC oscillators with one input calibrated 1V/oct. Hi-dynamic special Fm variable input.

    Sync mode : gated or hard sync (internal patch)

    Output : continuously variable square to sine wavevorm : continuously variable square to sawtooth waveform

    Audio mode : frequency range : Stop (no oscillation) - 1 Hz to 50 Khz

    LF mode : 0.01 Hz to 500 Hz

    Filter : 12 dB roll-off state variable filter with HiQ (at high settings distortion occurs. This make special tonal coloration , a remarkable feature of the µVentury II).

    2 inputs signals : line level available for one of them

    2 modulations input typically 1V/oct sensitive

    Continuously variable filter mode : from Lo-pass to Hi-pass, in between : all-pass (notch) filter.

    Four outputs available simultaneously : Lo-pass, Band-pass, Hi-pass, Notch

    Max Output level : 20V pp

    External source : Mic input/output, Line input/output

    Env follower input switched to Line output – Env follower output : 0 – 10V

    Gate generator : sensivity input switched to Line output : Gate out : 0 – 10V

    Ring modulators : Dual independant Ring Mod, one DC and one AC. DC ring mod can be used as a VCA.

    Wave X : Wave Multiplier can be best compared to the one of Serge, but even then it still sounds different.
    Internally switched output to input X (frequency doubling mode).

    Envelope generator : ADSR type (true RC envelope), VC control of ADSR curves by external board (optional), A : min +/- 2.5 ms --> +/- 20 sec, D : min +/- 2.5 ms --> +/- 20 sec, S : min 0V --> 10V, R : min +/- 2.5 ms --> +/- 20 sec

    Vu-meter : hardwired to lo-pass filter output (output signal read-out) and volume control knob
    Integrated 220-110V 2A dual power supply, illuminated switch with integrated fuseholder

    Case : rigid « attaché-case style » with aluminum finished borders (carrying strip and 2 keys included).


    Standard signal levels : All Ventury II modules handle ± 10 V. Frequency controls are either linear or exponential. Keyboard control input is calibrated 1V/octave.

    Standard impedances : All signals outputs are 1Kohm impedance, and can be shorted together through multiples for output mixing.

    All unattenuated inputs are 100Kohm, while attenuated inputs are 47, 33 or 15Kohm.

    Patch over firm-wire : Standard 6.35 jacks give total patching capability, firm-wire patches can be added behind (optional)

    Star type power signal distribution : for best results, we avoid the use of bus power distribution (noise, rumble,..), instead, each module is powered with his own cable.

    Obsolete circuits handling : As changes in the state-of-the-art make it practical to redesign to improve features, we shall update our circuitry. This increase the resale value of your Ventury II.

    Of course, replacements parts for old designs will always be available.

    Custom work : We are happy to quote on custom modifications when needed. Keep in mind that custom work is always much more expensive than standard products.
