[Matt’s] finishing up his computer science degree. As part of a class assignment he programmed his own sequencer which runs on a Cyclone-II FPGA development board. We’ve embedded a video below the fold that shows you what it can do. The buttons and LEDs offered on the board actually allowed him to create a nice user interface. Each slide switch has a surface mount LED above it, giving feedback for which beats in the loop are on and off. There’s also a bank of momentary-push buttons seen in blue above. [Matt] uses these to tweak settings like the pitch that is stored for each slide switch. He even puts on a light show with the VGA output.
We’ve seen this Altera board before, used to drive a falling sands game. The hardware will run you around $200 but that’s not bad considering all of the fun things you can do with it.

It’s totally excellent when a simple concept results in something inspiring and fun. [Rich Decibel]’s Kequencer is a good example, starting off as many projects do: “I had an idea the other day and I couldn’t decide if it was good or not so I just built it to find out.” Be still our hackable hearts!
[Rich] built this sleek little sequencer from scratch and while the design may not seem very novel to begin with–eight square wave oscillators with on/off switches and pitch knobs, played in sequence–but the beauty of it is in the nuances of interaction and the potential for further hacking. From watching the video you can see how the controls can be used in very interesting ways to create and mutate adorable chippy tone patterns. Check it out after the crossfade.

This sequencer, called Drumssette, uses audio tape to churn out some beats. [Mike Walters] built this around a Tascam four track cassette recorder. The tape inside has a different drum sound on each of the tracks, with a corresponding row of red buttons. Pushing a button adds the drum sound to the loop on that beat. He’s using a series of digital logic gates to patch through the sounds as well as clocking the device from one of the tape’s tracks. It’s pretty neat to see the focus selector used in the video after the break to sync up the beginning of the repeated drum patterns. This isn’t the first time we’ve seen [Mike’s] work. If you missed it last year take some time to review the Melloman.

This is the fourth generation MIDIbox sequencer which has a features set that’s several screens long. We’ve embedded the teaser video of this 16-track marvel after the break. You can use it via a traditional MIDI connection or with USB. Standalone Ethernet features are also in the works. It’s fully documented and you can etch your own PCB if you’re brave but it might be easier to get in on the group PCB buy if you just have to have one of these. There’s no all-in-one kit, but that will just make the taste of success sweeter once your soldering iron cools down.

[Yoshi Akai] built a sequencer that is part steampunk, part injection molded plastic. The LEGO sequencer MR II has eight steps in a loop that is manipulated by adding the colorful blocks to a green base plate. Each color corresponds to one particular sound which can be modified by building skyward. On the other side of things he’s added a beautifully crafted control area for knobs and switches. We didn’t see much info about what is inside the device so, watch the clip after the break and then feel free to start the speculation in the comments.
This is a similar concept to the coin sequencer. From the picture above it seems the blocks have been altered and perhaps use light to identify the different blocks.

[Moritz Wolpert] built this gem of Victorian hardware by hand. It is a sequencer and features beautiful detail work as shown in its MySpace gallery. Other than that we don’t know a lot about it. You can also take a look at [Moritz’s] main page, but prepare to be annoyed by the hideous web-styling that really undercuts the beauty of his physical product.

[Benjamin] built a sequencer that uses a turntable and light sensors to lay down a funky beat. If you like creepy videos with repeated gratuitous corderoy-clad rear-ends we’ve got you covered after the break. Art film aside, he’s got an interesting project. Four light sensors are mounted below the turning record with LEDs hovering above. His hatred for old LP records is apparent because holes must be drilled in a disc for the light to shine through. The four notes in the sequence can be altered in voice and color, along with controls for motor speed and direction. The project also has four manual inputs to add some variety to the repetitive beat sequence. It’s a bit less practical than the penny sequencer but fun none-the-less.
