Quasimidi Sirius

The Sirius is Quasimidi's souped-up keyboard similar to the RaveOLution 309 and aimed directly at the dance market. It's filled with knobs, buttons and cool colors. Designed for total control for live performance or studio work!

Actually most knobs are dedicated to patch editing. It has a welcome new feature, a modern vocoder! There are also 8 control knobs for setting various mixer-type settings (level, pan, fx send). That's right, it has effects on board! It's got a great sound too! Choose from basic categories like 'bass sounds', 'dirty bass', 'pad sounds', 808 & 909 kits and much more! There's plenty of memory (96 user patches) to store your own creations. The filter and envelopes are flexible and sound very good.

Also taken from the Rave-O-Lution is the incredible pattern-based seven track sequencer with part mutes and tap-tempo! A truly useful dance music production synth capable for demanding studio use and creative live performance control with excellent sounds and a funky new vocoder! An ideal all in-one-synth for any DJ or dance musician! It has been used by KMFDM/MDFMK founder Sascha Konietzko.

@ OohMikäJortikka... you're just an unfunny clown... the Sirius is worth at least $500.

"Est. Value - $1,695". Köhköh.. i'd say something like 200-250$. But personally i wouldn't pay even that.
Used Waldorf's give much better bang for the buck.

One of the best kept secrets for making this synth sound better is modifying the Overblast with a MIDI command in order to fix the EQing on this synth.

I would have to disagree with The .Invalid on how 'bad' this synth sounds today - listen to a few patches Jay B has made for it along with the Overblast trick -

although it does alias pretty badly, you just have to know how to make it alias the 'right' way

I should also add for the people arguing that since it's a full synthesizer that the only thing making it sound 'dated' are the presets - this is not strictly true.

The Sirius (unlike a lot of 'proper' synths) generates its sounds from sampled waveforms, and not true oscillators. If my memory serves me correctly, all the samples on board were 12-bit, and distinctively 'grainy' in sound because of this. This also had the side effect of most of the sounds producing horrible amounts of aliasing on the upper and lower octaves.
