Треугольник тоже отсутствует. По словам автора синус с треугольником могут быть сгенерированы фильтром.

"GS: Can you please give us a detailed overview of what the SCHMIDT will have on board in the final version?

Stefan Schmidt: The fair prototype is functionally already the final version, aside from some modifications to the casing and the software, which still has to be completed.

8 voices with multimode and single outputs
Access to all parameters of controls
Per Voice:

4 analogue oscillators
5 analogue filters:
2 Moog lowpass ladder filters with high pass, band-pass extension
2 dual multimode filters, distortion
1 12dB lowpass filter
Separate modulators (envelopes, LFOs) for filters and oscillators
Stereo panning
Separate master envelope
Filter crossfading function
Controllers: joystick, aftertouch, mod wheel, routable to all parameters
GS: Let us begin with the oscillators. As they are four in number they have quite a bit on offer. How would you characterise them?

Stefan Schmidt: The 4 oscillators differ mainly in their waveforms

Osc1: saw, square, pulse, noise, 4-Pulse, ring modulator
Osc2: saw, square, pulse, noise, ring modulator
Osc3: saw, square, pulse, sync + suboscillator
Osc4: multiple ring modulator, “metallic noise”
Triangle or sine-like spectra can be generated with a filter (of which there are plenty)."
