Multi Oscillator Linear Open Source Synthesizer MOLOSS is a virtual synth, available as a VST plugin or standandalone exe, to build analog vintage sounds by combining several techniques used in the 80's. Its 4 voices mix Subtractive synthesis, additive synthesis, frequency (or actually phase) modulation, cross modulation, to allow a very wide sound range, with a lightweight CPU load. It has a default polyphony of 64 notes, and 2 mono "solo" modes. A lot of parameters can be modulated with controllers, to give the best live expressivity.
