Sinthecyza! 3 has had a major overhaul and now includes an 8 Voice Unison Oscillator courtesy of Etric Van Mayer of EVM Synths.
Sinthecyza! 4 now includes the ability to select the waves for both the Main and Sub Oscillators.
Both synths have had all the envelopes expanded upon with a ‘Hold’ level stage in all three, and a additional ‘Delay’ stage in the filter envelopes.
Both synths can be downloaded free of charge from the Sonic Assault site.
