Mopar is a synth that combines a phase distortion oscillator with a SoundFont oscillator to produce, amongst other sounds, cool pads.
Osc1 has 8 waveforms (saw, square, pulse, double sine, saw-pulse, reso1, reso2 and reso3). These are the waveforms you obtain when the modulation level is at its maximum. At its minimum, the oscillator produces a sine wave. The modulation level can be modulated by a filter and by the LFO.
Osc2 has 6 waveforms (choir, brass, accordion, organ, dream and strings).
The 2 oscillators share the same amplitude envelope (ADSR) but you can adjust the volume of each oscillator separately.
You can also adjust the master volume and the bender range (from 1 to 12 semitones) and the portamento time.
