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.

Operative system sometimes unstable.

In general bad sound... but great in the mix.

These were geared towards one thing only but they do it well; techno/dance. The interface is a bit different than what most are used to but one will quickly figure it out as it is fairly straightforward. Though somewhat scarce, these can be found but prices vary depending on who's selling it. Very high quality but finding parts might prove difficult since Quasimidi is no longer in business.

One of the users here said it's starting to sound a bit dated....I can only assume he's talking about the presets, I can't imagine how a synth it's can sound dated in the hands of a competent programmer...

I fell in love with the sound that quasimidi synths have from the first moment i played one. When I eventually had enough money to get a studio together they had vanished from the market. To make matters worse nobody ever imported them into the country that I live in.
Over the years I accumulated a virus C and a waldorf micro Q along with various other oddities, but I still craved a Quasimidi. Particularly the Sirius. To me they are the epitome of the "dance" sound.

I found one in a pawn shop last year. They clearly had no idea what it was and it was in perfect condition including it's manual. Some guy was testing it out and my heart rate raced as he sat there twiddling it. Eventually he took the headphones off, looked at me and said "nah, its too techno for me" and walked away. I promptly grabbed it after he left, marched to the front desk and paid the equivalent of 150USD for it.
