Triceratops is an analogue style polyphonic subtractive synthesizer plugin, for use with the LV2 plug architecture, at this time there is no standalone version. An up to date version of the LV2 library is required along with a suitable host (e.g. Qtractor, Jalv, Ardour), I highly recommend either the KXstudio distro or the KXstudio ubuntu repositories! The intention is for this synth to be part of a suite including a drum machine (Stegosaurus) and a wavetable synth (Dracorex), watch this space.
Nice synth! Lots of modulation effects, aggressive filters, rich-sounding oscillators. Thank you for this update!
