Quasimidi Sirius

Quasimidi Sirius Image

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.

Fantastic machine everything you could want from an analogue modelling synth, real hands on feel, loads of editing capabilities, amazing arpeggiator and great on board sequencer, one of the best. Just got one absolutely preestene, great stuff.

I bought my Sirius in the summer of last year (2008). The guy i got it from looked after it well:) however he said he could never figure it out. I spent a few hours and managed to program a new soundset aimed towards minimal house. I have programmed anything from subby basses to sizzling pads and the lead sounds are in a league of there own. I Actually managed to get a kick drum out of this machine that was fat and polished without any eq or compression. Thats a 1st for most synths. The sounds sit in the mix better than any vst plugin or even many synths double the price. The sound is just plain amazing. Its only dated if you program dated sounds, but its the bass and bloops that make this a real keeper in my studio.
I find it very easy to program.

Be careful with the power supply, it's one ov those lump-in-the-middle types that, if damaged, can be problematic since Quasimidi is defunct.
Other than that, it's features are nice given the price range, however, it has a STEEP high frequency cutoff point.

Just picked up a lovely one from a great previous owner. Went through some demo sounds. Very very good sound sculpting abilities. I agree with others that stated the quasimidi's have their own sound. I have the 309 & the Quasar. That grit is in all 3, but the quasar is basically all presets and the 309 cant do everything the Sirius does. Plus I do have the extra outs on the 309 so thats better for drums. It looks great. Feels pretty solid, sounds Raw Rude & in charge. I'm sure it will keep me busy with new dark twisted sounds for a long time. Peace! Tha RecordMonster!
