The SKQ-01 is a more extreme take on FM synthesis, offering 9 different waveforms as well as PWM (Pulse-Width-Modulation) and allows you to create anything from trippy FM pads to the most noisy and loud bass lines.

Besides the FM synthesis mode the synth can also be switched to a normal synthesis mode so that the two oscillators can be layered, for a nice full sound which lends itself for things such as massive pads.

There are two oscillators/operators giving 16 note polyphony. Each of these has it's own waveform, detuning and ADSR envelope.
The second oscillator/operator has PWM which can be used both in FM as normal synthesis modes.
The synth also features an analog emulation of a low-pass VCF with plenty of resonance available, which can be controlled with a separate AR envelope as well as an LFO.

For further shaping of the sound there is a distortion, stereo chorus and reverb effect build in. For extra dynamics in your playing Portamento and Pitch Bend can be used.

Patches can be saved and loaded from within the plugin.

- Completely rewritten the stereo chorus to make it sound much, much better. It now adds that classic vibe to your sounds.
- Waveforms have been revamped, making them less abrasive as some had too much high frequency content.
- Filter has been rewritten as well, now being more true to the hardware version.
