Elegant Drum Machine from Teensy

Posted on by

Playing the drums is pretty hard, especially for the uncoordinated. Doing four things at the same time, all while keeping an even tempo, isn’t reasonable for most of us. Rather than hiring a drummer for your band who is well versed in this art, though, you might opt instead to outsource this job to a machine instead. It’s cheaper and also less likely to result in spontaneous combustion.

This drum machine is actually a MIDI Euclidean sequencer. Euclidean rhythms are interesting in their own regard, but the basics are that a common denominator between two beats is found in order …read more

Learn What Did and Didn’t Work In this Prototyping Post-Mortem

Posted on by

[Tommy] is a one-man-shop making electronic musical things, but that’s not what this post is about. This post is about the outstanding prototyping post-mortem he wrote up about his attempt to turn his Four-Step Octaved Sequencer into a viable product. [Tommy] had originally made a hand-soldered one-off whose performance belied its simple innards, and decided to try to turn it into a product. Short version: he says that someday there will be some kind of sequencer product like it available from him, “[B]ut it won’t be this one. This one will go on my shelf as a reminder of how …read more

Basic Sequencer for your Synth Rack

Posted on by

Sequencers are useful for bringing regular structure to your music, particularly if you enjoy noodling around with rackmount synthesizers. [little-scale] is here to share an ADC Binary Gate sequencer for your setup.

In a quest for ever greater minimalism, the build relies on a barebones ATMega328p without an external oscillator. Instead, the chip’s internal RC oscillator is used instead. It’s possible to still use this with the Arduino IDE, as [little-scale] shares here.

The music production begins with a clock input signal, which is patched in from elsewhere in the rack synth. The sequencing is controlled with potentiometers. There are …read more

The Grafofon: An Optomechanical Sequencer

Posted on by
There are quick hacks, there are weekend projects and then there are years long journeys towards completion.  [Boris Vitazek]’s grafofon falls into the latter category. His creation can best be described as electromechanical sequencer synthesizer with a multiplayer mode.
The storage medium and interface for this sequencer is a thirteen-meter loop of paper that is mounted like a conveyor belt. Music is composed by drawing on the paper or placing objects on it. This is usually done by the audience and the fact that the marker isn’t erased make the result collaborative and incremental.
 These ‘scores’ are read by a

Four Chords Should Be Enough For Anyone

Posted on by

You might be surprised at how many pop songs are exactly the same. Cat Scratch Fever is the exact same song as Smoke on the Water. Even one of Yeezy’s songs is strikingly similar to a weird 90s French electronic group. Musically, though, there are an incredible number of songs that follow a I-V-vi-IV progression. Let it Be is one of them, as is Beast of Burden. aLady Gaga’s Poker Face is another. Now, finally, we have automated most of the pop songs you know and love. [Sven] has created a small MIDI device that only plays a I-V-vi-IV progression, …read more

Hackaday Prize Entry: Zappotron Super Sequencer

Posted on by

If you fancy a go at circuit bending, where do you start? Perhaps you find a discarded musical toy at a junk sale and have a poke around, maybe you find the timing circuit and pull it a little to produce a pitch bend. Add a few wires, see what interesting things you can do connecting point A to point B, that kind of thing.

Many of us have spent an entertaining afternoon playing in this way, though it’s probable few of us have achieved much of note. [Russell Kramer] however must have persevered to become a circuit bender par …read more

LEGO Looper Makes Modular Music

Posted on by

This LEGO synth made by [Rare Beasts] had us grinning from ear to ear.

It combines elements from LEGO Mindstorms with regular blocks in order to make music with color. A different music sample is assigned to each of five colors: red, blue, green, yellow, and white. The blocks are attached to spokes coming off of a wheel made with NXT. As the wheel turns, the blocks pass in front of a fixed color sensor that reads the color and plays the corresponding sample. The samples are different lengths, so changing the speed of the wheel makes for some interesting …read more

Orbs Light to Billie Jean on this Huge Sequencer

Posted on by

Sequencers allow you to compose a melody just by drawing the notes onto a 2D grid, virtually turning anyone with a moderate feel for pitch and rhythm into an electronic music producer. For  [Yuvi Gerstein’s] large-scale grid MIDI sequencer GRIDI makes music making even more accessible.

Instead of buttons, GRIDI uses balls to set the notes. Once they’re placed in one of the dents in the large board, they will play a note the next time the cursor bar passes by. 256 RGB LEDs in the 16 x 16 ball grid array illuminate the balls in a certain color depending …read more
