Here’s a demo of the Electro-Harmonix 8 Step Program Analog Expression/CV Sequencer by “JJ Likes Guitar.”
The 8 Step Program plugs into the expression pedal or CV input of other effects pedals and synthesizers delivering rhythmic sequencer control. It can turn an ordinary auto-wah into a step filter, a tremolo into a syncopated pulse effect and a pitch-shifter into an arpeggiator. Here JJ shows what it can do with the Stereo Talking Machine Vocal Formant Filter and the Ring Thing Single Sideband Modulator.
