Behringer 960 Sequential Controller (Moog System-55 Clone) Eurorack sequencer. RRP £99
3 lines, with 2 cv out each, of 8 steps, with trig in and out, selector button and step mode (play, skip, stop).
There's an onboard clock in the shape of a square oscillator with coarse and fine control, osc out (to triggers, typically) and cv in for frequency. A switch patches the third line to this giving you control of step lengths on the pot.
A classic of analog bleep-booping. I sell a companion 962 sequential switch that lets you chain lines to 16 or 24 steps, as well as other modules (I'm slowly listing a whole batch), check these out.
