A couple of features make it really cool: * You can add a (keyboard) CV to the output voltages * A 3-position switch for each slider can be used to trigger other devices * it has 2 independent voltage quantizers that round off voltages to the nearest 1/12 V. This comes in very handy, because the CV's are set using sliders. * Best of all: its REALLY fast: if you connect the output of a VCO to the Step input, and listen to the sequencer unquantized output (A or B), you hear a waveform 3 or 4 octaves below the VCO's pitch, depending on the setting of the 8/16 switch. You can draw your own 8/16 step waveforms with the faders! My favourite trick: - Set the sequencer to 2*8 - Connect the Step input to the VCO - Mix the output A with the VCO-out (optional) - send the output to a VCF - Control the cutoff of the VCF with sequencer output B (the secret ingredient) - Process through VCA, envelope PS: Don't bother trying this with an (unmodified) SQ-10 or a MAQ 3/16: they can't step at audio-rate.
