Alesis QSR

QSR - Rack mount model

The QSR is identical to the QS7 and QS8, except that it is a keyboard-less rackmount version. Also lost are the real-time controllers, but the two PCMCIA expansion slots are easily accessible right from the front of the unit. It's LCD display, on the other hand, is much larger than the keyboard version which makes navigating and editing easier. A great source of Alesis' brand of high quality synthesis and sounds! It featured 16 MegaBytes of sample/synthesis ROM (and is expandable to 32 MegaBytes), 4 stereo outputs, discrete MIDI OUT and THRU ports, ADAT optical digital output and a 48kHz clock input.

The QSR is undoubtedly a powerful and flexible synthesizer capable of creating rich sounds - both acoustic and electronic. There's 64 voices of polyphony and 16 parts multitimbrality and tons of memory and expand-ability! The QSR uses digital additive/subtractive sample playback synthesis to create high quality stereo grand pianos, organs, strings, drums/percussion, brass, woodwinds, new and classic synth textures, General MIDI, and rhythmic/sonic loops. Most of them sound pretty darn great too!

The QSR implements the powerful QS Modulation Matrix, allowing users to assign virtually any controller source to any modulation parameter. There's an onboard multi-effects processor (based on the QuadraVerb 2) with four totally discrete effects busses that include reverb, delay, rotary speaker simulation, distortion, chorus and much more. With a direct Mac or PC hook-up, loading patches and editing via software is a snap! QS synths shipped with Alesis' Sound Bridge software for Mac/PC which lets you write AIFF and WAV samples, Standard MIDI Files and Program data to PCMCIA Flash or SRAM cards. It can play Standard MIDI file sequences from the expansion cards without the use of an external sequencer. For a Studio-quality synthesizer module that isn't focused just on dance or trance, be sure to consider the QSR.

The QSR claims to have 64 voices of polyphony, and that is true, literally. (or at least that seems to be the case) If you're using a patch that is comprised of 4 waveforms/samples, (I'm NOT talking about Mix/Combo mode w/multiple patches) it's seems like the QSR has only 16 "NOTES" of polyphony. When using a string/pad patch w/a long decay & switching between 6-7 note chords, I consistently encounter...ummm...(what's the word?), the notes "cut-off". When that happens, if the patch has a long decay & slow attack, when you play the next chord, the patch has a very sharp/sudden attack. Weird.

Fair to decent sound module. Sound wise, it's maybe a little better than my Emu Mo-Phatt, but the Emu has much better resonance filters (though they're not great either) & a controllable appregiator. None of the acoustic sounds are very good by today's standards, even with QCards. Drum sounds are just OK. Techno & Vintage Keys QCards are cool. There's a stock, string/synth pad on the QSR that is great & HUGE! (it's worth it just for that) & a few, nice, hollow & metallic pads. That's all I really use my QSR for. Pound for pound/$ for $, the Roland JV1010 is MUCH better. (less expensive too)

I love it! I purchased one for less than 150€ and it sounds amazing. Love the the ambience/textures, the strings, the pianos, the percussions/drums... everything! This little monster has helped me a lot in creating soundscapes for a lot of short films.
