Description
Version 2 of the Opera 6 from Siel featured 6 voices with 12 Voltage Controlled Oscillators and is very similar in look and style as the original with a new blue casing, pitch and mod wheels, and repositioned buttons allowing more space for the user to perform functions. The synthesizer's architecture is still a 6 voice unit with 12 voltage controlled featuring square and saw waveforms with pulse width modulation. The Opera 6 has MIDI note on/off with velocity and program change only. Backups could be performed over MIDI as well and also tape backup is available. A pitch wheel was added alongside the original's mod single wheel.
