| Notes | The Opera 6 is a classic, early eighties analog 6-voice polyphonic synthesizer that was in the same class as the Roland Juno series. The Opera 6 came in three versions as it was developing during its lifetime. First there was a totally analog version with an Oberheim-style pin-stripe control panel and one modulation wheel. A matrix of push-buttons enabled program selection. The later versions replaced the VCOs with DCOs. This meant more stable tuning without compromising the analog sound. Then, MIDI was also added (with velocity response ability).
The Siel DK-600 was an Opera 6 with different artwork. The last EPROM supports MIDI channels/Omni off
The Siel Expander EX-600 was an Opera 6/DK600 in a table top module. Only dco B tune, Volume, master tune controls, the rest are controlled over midi
