Critic Reviews

Alesis QSR

soundonsound.com

Alesis QSR impresses with its clean, rich sounds and excellent effects processing, making it a solid choice for musicians seeking a reliable multitimbral module. The two PCMCIA expansion slots offer versatility, and the direct ADAT connection is a bonus. While the editing can be fiddly due to limited buttons and the lack of filter resonance is noticeable, the extensive modulation options and switchable GM mode elevate its performance. Ideal for players prioritizing instant, high-quality sounds over deep programming, the QSR is a classy act with a few minor drawbacks.

With Sanctuary card is unbeatable

I've bought it second-hand only for the fabulous pipe organ samples: with the Sanctuary card it has 20 different pipe organ samples, rich and full of realism. The polytimbric architecture allows to have a multiple keyboards setup with several organ registrations.
