QuadraSID is much more than a simple emulation of an SID chip (the real chip that was used in synthesizers). Enriched with many new features (e.g. arpeggiator, four LFOs, waveforms), this software instrument provides unlimited sonic possibilities, and is able to surprise even the most experienced professional with its flexibility. Each QuadraSID-loaded sample emulates four SID chips simultaneously – with four separate stereo outputs and MIDI-controlled controllers.
