TSL have a couple of step sequencers - the Stepper Acid is a 303 style sequencer geared towards the good old acid style with CV, Gate, Slide and Accent out - designed for live performance simplifying the programming process for on the fly. Also on show was the Stepper Drum Sequencer which is an 8 channel trigger sequencer.
Sadly the component shortage is putting the brakes on production, but they should be coming back on-stream soon.
