AWESOME SOUNDS, GREAT ACTION, UNBELIEVABLE VALUE.

Alesis introduced the QS8 in 1996, and shattered the price barrier for professional 88-note keyboards. Normal working musicians — and those just aspiring to work more — could suddenly afford a no-compromise instrument for a very compromising price, and this tradition continues with the QS6.2 and QS8.2.

Featuring serious sounds for serious players, the QS synths are loaded with stunning pianos and keyboards, a soup-to-nuts collection of orchestral instruments, killer drum and percussion kits, and enough amazing synth textures, fat basses, and sizzling leads to keep dance musicians and remixers grooving into the next time zone. A deep programmable synth architecture and four-bus effects processor add the finishing touches. And a wide variety of fresh samples are available from our extensive QCard library.

Whether you need an 88-note workhorse or a do-it-all synth, the QS8.2 and QS6.2 keep your fingers flying for a down-to-earth price.

  • How do I reinitialize my QS6 keyboard?

    Power on while holding: Keypad buttons "0" and "3".

    Evidence: Program and Mix modes will both show "0" as the selected number with a name made of two quotation marks. An initialized program will be active consisting of a single pure sinewave.
    Note: Does NOT clear memory
    Resets the QuadraSynth's Global functions, but leaves the Mix, Program, and Effect memory intact in the User Bank. The Preset Bank is unaffected, as it is permanently stored in the keyboard's ROM (Read Only Memory).
