DESCRIPTION:
This is the second sequencer I have designed and created. It is an eight step sequencer built around a 4017 decade chip. It has a toggle switch that can switch between a full gated step or a pulsed trigger. Each step can be switched on or off and each step also has a voltage control that can be sent to a VCO. The step repeat can be varied between 2, 3, 4, 5, 6, 7, and 8 steps.

I shot this video before I had the knobs for the voltage control pots, which is why they are missing. Also, I am only demonstrating the trigger control on the Casio-SK1's sequencer. I sequenced a little tune and then let the sequencer trigger the sequence via the one note playback hack I did on the SK1.

The sequencer does not have its own clock. Instead it is gets its clock signal from an external source, in this case from my for step sequencer on the left.

I economically purchased the parts from the Reuseum in Boise. Here is their site: http://www.reuseum.com

The edges are a bit rough as I cut all the openings into the project box with a cheap switch blade.

Just recently I took the sequencer over to my friends palce and he shot some video as I showed him this sequencer. Here is his youtube post: http://www.youtube.com/watch?v=Sg6ukKTCK7M
