Sujet Namm, Messe, toutes ces nouveautés.... et ces synthés qu'on a déjà !

korg W8000 (ou je sais plus son nom).

J'attends toujours un analogique polyphonique avec 10/12 voix, polytimbral 2 ou plus, des boutons partout, et plein de modulations pour craquer à coup sûr.

analogique le parva ?

100% Analog Sound

From the oscillators and wave-shapers to the voltage-controlled filters (VCF) and snappy OTA-based voltage-controlled amplifiers (VCA), Parva's signal path is 100% analog. There's no DSP here.

je ne lance pas le débat

Traditionally, analog synthesizers have used voltage-controlled oscillators, which generate a waveform at a frequency proportional to the input voltage. There are various designs, some more stable than others, but they generally tend to suffer from frequency drift over time, and are sensitive to variations in temperature. This produces both desirable (rich, thick tones) and undesirable (out-of-tune) effects. With the advent of MIDI, VCOs effectively became digitally-controlled — using a processor and DAC to translate a MIDI note into the proper voltage to produce the desired frequency.

If the goal is digital control of an analog oscillator, why not eliminate the middleman — voltage control — and directly control the oscillation frequency?

Each of Parva’s digitally-controlled oscillators utilizes the same type of “ramp core” used in many VCOs: an op-amp integrator charges a capacitor and produces a linearly increasing voltage at its output. By discharging the capacitor at regular intervals, an analog sawtooth or ramp waveform is generated. That waveform can then be fed to various wave-shaping circuits — Parva includes triangle and pulse waveforms in addition to sawtooth.
