z3ta+ is rgc:audio's flagship instrument, which extends the capabilities of their virtual analog synthesizers line (Triangle, Square & Pentagon) by introducing their exclusive Band limited Waveshaping technology.

As a complete instrument, z3ta+ is oriented to the professional musician and sound programmer looking for uncompromised sound quality and features.

Features:

- Oscillators Section

• 32-bit wavetable synthesis with three interpolation modes (DRAFT, NQ, HQ).
• Full Stereo processing.
• 6 Oscillators, 60 built-in waveforms, 10 user loadable waveforms, PWM capable in all oscillators with any waveform.
• Loadable Wavetable Sets: Programs using different wavetable sets can be mixed in a bank. z3ta+ will find and load the appropriate wavetable set when the program is selected on-the-fly.
• Loadable Oscillator USER Waveforms: z3ta+ can load the USER oscillator waveforms 1 to 6 from standard wave files (.wav). Up to six individual waveforms can be loaded per program, and then transformed by using the shaper as the internal waveform set. It is possible to load different waveforms in each preset. z3ta+ will find and reload the used waveforms when the program is selected on-the-fly. The wave files must be mono, up to 64k samples, in any samplerate.
