Performance features. The TS offered the ubiquitous pair of modulation and pitch wheels, polyphonic aftertouch, and 'patch select' buttons for easily changing tonal variants of a patch. It was very easy to layer up to three single sounds, or split the keyboard in all zones for internal or MIDI playing control, without cumbersome menu editing. It was also possible to layer up to six single sounds by taking advantage of the live-auditioning feature of the sequencer (without actually recording or playing back anything), but this was less easy to manage in a performance environment.
