DSP/Real-time VST synths [no wavetable/ROMplers]

This may be naive, but aren't all software synthesizers wavetable-based? 

Better reproduction of analog oscillators

TAE^® oscillators are very similar to their analog counterparts for several important reasons.

One of the main reasons is that they are "free", i.e. they are not sampled or wavetable based - or generated from a 0-point when a note is played. Each waveform generated dynamically, allowing the waveform to be in constant adaptation regarding sampling "cutting" and quantization, avoiding one of the major "tell-tale" signs of digital waveform generation and provides a certain level of "liveness" found in the classic analog synthesizers of the past.

Standard digital synthesizers produce aliasing in high frequencies, and also when using Pulse Width Modulation or Frequency Modulation. TAE^® allows the production of oscillators that are totally aliasing-free in all contexts (PWM, FM,…), at no extra CPU cost.

Also, all of our oscillators are highly optimized for the particular working frequency. That means that you can play with an instrument exactly as if you played a real analog synthesizer. Again, the waveforms are not presampled and or regenerated with digital perfection, allowing each note to have a life of its own.

In addition, original analog oscillators were unstable. Actually, their wave shape was always slightly different from one period to another. It is also true that due to analog hardware sensitivity, new period trigger times varied with the temperature and other environmental conditions.

TAE^® allows the simulation of the oscillator's instability, helping to create warmer and fatter sound.

Original analog oscillators used condensers' unloading to produce common wave shapes (saw tooth, triangle, square). This means that wave forms were slightly curved or distorted in other ways that are considered highly desirable in a musical context. TAE^® allows the reproduction of condenser's unload in order to give you the original analog sound.

Because TAE^® oscillators are "free" and "alive", when you play a simple chords with raw oscillators, you don't have a digital impression of "fog" or a "blocked" sound, but you have a pleasant feeling of transparency and clarity.


PWM

With TAE^®, you can even produce complex PWM sounds with unprecedented quality and, of course, free of any aliasing. It is true for all the our TAE^® waveforms (square, triangle, saw…). This produces sounds which are unique on the market, because PWM is very difficult to achieve on certain waveforms like triangle or saw/ramp. We bring you new levels of reality in a virtual analog synthesizer, so that you can achieve new levels of creativity in your music.[/quote

So I would go by the resulting sound rather than some preconception about what approach is better.

I don't get it.

If you simply want a synth based on an oscilator how can a new one be anything different than an ancient one?

Oversampled modulation??? WTF. It seems like useful range for "modulation" is so small that oversampling solves a problem that doesn't exist.

What's next? 

7 string guitars? :-)


all the best,

There is no limit to the potential complexity of a wavetable. The idea is that you calculate the waveform once and then repeat it 100,000 times. You don't recalculate it for every cycle.
