Finished Pieces


I’ve been playing with mechanical sequencers for a few years. The sequencer allows you to automate things not traditionally automated (like a baby drum toy or speak and spell) and unify traditionally incompatible musical systems(like….. a baby drum toy or speak and spell).
A theme I enjoy working with is strength highlighted by contrast. Connecting two conceptually separate elements into a single unified voice creates a powerful dynamic. The mechanical sequencer is also interesting in it’s imperfections. Each cam is hand made and while it is close to perfect, it’s not perfect. That in conjunction with characteristics of the control motor translates into subtle inconsistencies in the sequence. This pulls the composition away from the glossy computer sequenced alternative.

This project was born in 2002 when I found an industrial, cam shaft, event sequencer pictured below.
I wired up the sequencer to a patch bay interface so I could experiment with using the sequencer to control various devices.

As the cam shaft turns, each cam presses down on a switch. The pattern on the cam determines the rhythmic cycle of switching. Each switch is wired to two patch points on the patch bay. When the switch is pressed it connects the two patch points.
I can use the sequencer to control almost any electronic device by wiring the buttons and switches on that device to patch points. Then I wire those points to the switches of the sequencer.

    reminds me of the furby gurdy, would love to hear what it sounds through patched to some of your bent synths.

    Yoni, There are a bunch of samples in the music player right above your comment.

    Great stuff. I hope some day you make it out to Seattle.

    Could you please create a Sequencer for bent toys that can sync to external clock and put it in a for sale format like the Drone labs? I have a bunch of bent creations, as do many people, a device to bring some order to the kaoss, would change circuit bending as a music making platform. Consider it please, or point me in the direction of making something of the sort myself! Thank you for the world class experimenting

    I just want to second what Ben said, I’m looking for exactly the same thing. I supported a kickstarter project for this once, but it didnt get enough funding. You can do it Casper! It will make you rich!!

    the secret is an arduino and a bunch of transistors. I did a bunch this summer. exciting stuff! I’m hoping to put up schematics and code soon.

    Hi Casper, is there a way to make a digital mechanical style sequencer (momentarily switching on bends)? I’d like to sync my sk1 with my speak and math.
