 In 1998, Alesis upgraded the QS line with the QS6.1, QS7.1 and QS8.1, which were basically the same as the original QS line, except that Alesis created a new 8MB Bosendorfer Stereo Grand Piano sample for them.Also, a bigger LCD screen, and a few extra assignable sliders (for performance tweaking) were included.In 2003, Alesis decided to keep the QS series alive with the QS6.2 and QS8.2 (there was no 76-key version).
