réactions à la news [SUPERBOOTH] Novation présente Peak

J ai eu plein de machines avec lesquelles la relation était totalement stérile

Et comme rappelé plus haut: FM et Tables d'ondes...

l'ultra nova et le mininova le font déjà

Le Prophet VS, le PPG, le Microwave, le Blofeld, le Micromonsta le font aussi, si on va par là inutile à Dave Smith de faire un P6 puisque le P5 le fait...
On parle ici des possibilités intrinsèques d'une machine par rapport au jugement qu'induit le prix et ce jugement me semble injuste par rapport aux possibilités de ce synthé, maintenant que ce soit ou non à nos gouts respectifs est un autre débat...

il ressemble au moteur du mininova

The FPGA: Higher Ground

Central to Peak is the use of a high-powered processor component called a Field Programmable Gate Array (FPGA). In contrast to traditional DSP chips, which often need to run in pairs or quads, the FPGA is a single processor on which many functions can run — from oscillators to the modulation matrix. The key benefit to an FPGA is that it runs at a much higher rate than DSP-based technology, and this has a direct impact on the clarity of sound.

Each of Peak’s eight voices has an independent oversampling digital-to-analogue converter (DAC). These DAC’s are oversampling at over 24MHz (24 million times per second), using a simple RC (resistor-capacitor) filter on their output in the analogue domain. In itself this is not new technology, but their integration inside the FPGA has enabled their design to be extended to enable optimum waveform synthesis. Because other virtual synths use discrete ‘off the shelf’ DAC chips, which are restricted to running at sample rates of either 48kHz or perhaps 96kHz, they often have aliasing issues, especially when synthesising higher frequencies. Peak’s ability to generate waveforms at the oversampling frequency — up to 512 times the traditional rate — ensures that Peak’s waveforms are pure at all frequencies, free from digital artifacts no matter how aggressively the pitch is modulated.

L'aliasing est fortement éliminé et on se rapproche encore un peu du mythique VCO mais est-ce que ca s'entend réellement?

Moi non plus il ne me botte pas plus que ça mais au vu des spécifications données, le comparer à un VA est hors de propos, on est au delà du VA classique et en effet plus proche d ’un Modal...

C'est quoi la différence entre un Modal et un VA comme le JD-XA System-8 nordlead A1 et 4 ? ces derniers fonctionne bien en 24 96khz non ?

Analogue / digital hybrid architecture uses NCOs for very high resolution, and very stable oscillators. Over 50 different waveforms, ranging from classic analogue sounds to more unique digital shapes
Modal Electronics designed 24dB per octave four pole transistor ladder filter, with some very unusual morphing characteristics or ‘polesweeping’, enabling transition from four pole through bandpass to one pole 6db per octave, or anywhere in between

C'est de l'hybride, t'es borné parfois Pico...
