Alesis QS6.1

The QS6.1 is a 64 Voice Expandable Synthesizer and is a much more improved version of the QS6 QuadraSynth. With double the sound memory, the QS6.1 has 16MB of digital ROM samples, double the expansion capabilities, double the real-time control sliders, and a much improved and larger LCD display screen. The QS6.1 has a vast set of sounds containing a library of 640 programs and 500 multitimbral mixes. Really amazing pianos, orchestral sounds as well as vintage synth sounds, strings, brass, winds, guitars, drums, percussion loops and groove patterns can all be found here.

The QS6.1 features 64 multitimbral parts over 16 MIDI channels. That's a lot. And since it's 64 voices polyphonic, you can arrange some pretty complex and complete music, from full orchestras to trance dance tracks, beats and sfx heaven! The keyboard can be split into 16-zones! Control the volume, panning, transposition, effects level and more of each channel independently. Four on-board edit/control sliders are assignable to most modulation parameters. Onboard multi-effects based on the QuadraVerb 2 include reverb, chorus, distortion, EQ, delay, rotary speaker simulation and more. These are on four independent busses so it's like having four FX units!

Powerful MIDI implementation suits the QS6.1 for any studio situation. But it has more! It can connect to your Mac or PC using its RS422 or RS232 ports. The QS6.1 comes with a CD-rom (Mac/PC) with Alesis' Sound Bridge and FreeLoader applications, plus programs for sequencing, editor/librarians, notation, extra samples, programs and mixes, sample sequences, demos and more. Either way you choose to use the QS6.1 it is a truly professional yet affordable versatile and compact synth capable of just about anything you can dream up. For more robust studio applications and demanding players, the QS7.1 (76-key) and QS8.1 (88-key) models were also released in 1999.

The QS6.2 is virtually identical to the QS6.1 except that it has only one expansion slot to the 6.1's two and it has a bright shiny new silver design. The ROM Soundsets may also be a slightly newer version too.

Very solid feel to this well built machine, got version 6.2 brand new for £199, must of been sitting in the shops warehouse for awhile. Have to say it's worth every penny, the sounds are pretty cool and once you start to dig into the machine you find many editing options. The drumsets are excellent, kinda whacky and editable. Never tried one of the elusive Q cards but I'm sure you can download the sounds from their site.

I use one of these synths for about three years. I like it very much for its organ and E. Piano sounds, great semi-weighed keyboard, etc. Only my claim was the accoustic piano sound. I have found one man in USA who produces and sells (legal) copies of QCards and I bought the Jazz Piano card. I must recommend this instrument and card for everyone who needs organ and piano sounds in light packaging.

I've had one for years. It is excellent for the price although a bit hard to edit. I am looking for a memory expansion card. Anyone know where I can get one?
