Alesis QS6.1 / QS6.2

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.

I've owned this for many years now. I needed the four programmable sliders to act as faux drawbars for my Emu B3 module. I own the S4+ module too so I knew the sounds were good. The midi implementation is great. Nothing else on the market can touch it especially at it's price.The ability to use int. ext.or both sounds per zone and-well, you get the picture.I do have some gripes about it ; Alesis has virtually no cust. service, not since they were bought by Newmark. Bank change commands aren't real programmable.Only sends CC#0 values of 1-13 I think. Intended for use with their own modules with a User, 3 preset banks, GM bank and 2 Q-card banks. I'm sure this was done for cost reduction but it's huge when controlling other brand modules.Shame they've discontinued it.A few software tweeks such as the bank messages and a resonant filter, this could have been THE all-time greatest contoller\synth ever. I'd have paid more for the added features.

Owned this tank for close to 10 years now. I bought it refurb'd and it had a huge ding in the bottom casing and I gigged it w/ my garage band for a couple months. It's a tank and can take a good deal of abuse (of course, the innards are pretty sparse and surrounded by solid metal). After a deal of abuse it still works great.

Only problem I started to notice is that pads will randomly alias when sustained and my pitch wheel floats +/- a few cents at some times. Alesis offered no support aside from telling me to take it to a tech. It probably just needs a shot of compressed air though...

Editing is a CHORE and there is no filter resonance. However it's pretty deep if you have the guts to dig into her. It is a ROMpler, so don't expect anything spectacular.

I bought a 6.2 and when I try to plug it into an amp it I get tons of noise. I checked the cord and amp with my other keys and its fine. When I use headphones they are fine. Is there some type of stting. It does it on all the outputs. It even does it when I turn it off. Im stuck
