Moloss – Free open source synthesizer by Arthelion
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. Additionally you’ll find a full embedded file-based preset management.
