Alesis QS8 88-note weighted piano action synth in very good condition. Used as practice keyboard; has new patch memory battery and new blue (was yellow) display. Great sounding synth with 600+ patches, programs, and mixes (program layers stacked). Critical review at https://www.soundonsound.com/reviews/alesis-qs8. Great piano action on a 64-voice synth with great FX processor & flexibility. Easy user interface & learning curve; a keyboard you won't outgrow in a month. Selling for $250 with owners manual on CD.
