Planet Arduino

You could sometimes be forgiven for thinking that making popular music has become too easy. With a laptop and suitable software almost anybody can now assemble something that had they secured the services of a canny promoter would be in with a shot at stardom. So many performances have been reduced to tightly choreographed dance acts to mask the absence of musicians or indeed musical talent, and our culture is poorer for it. It’s not that music made with modern technology or outside the performance is an indicator of lack of talent, indeed when a truly talented musician makes something with the resources of a modern technology the results are astounding. Instead it perhaps seems as though the technology is cheapened by an association with mediocrity when it should be a tool of greatness.

So it was with pleasure that we noticed a fresh project on Hackaday.io this morning which provides a marriage of accessible music technology and a requirement for performance. [Ernest Warzocha] has made a wooden sequencer.

It’s true, audio sequencers are old hat, so a new one will have to work hard to enthuse a seasoned Hackaday reader who’s seen it all. What makes [Ernest’s] sequencer different is that he’s made one with a very physical interface of wooden pucks placed in circular recesses on a wooden surface. Each recess has an infra-red reflective sensor that detects the surface texture of the puck placed in it and varies the sample it plays accordingly. It’s all held together underneath by an Arduino, and MP3 samples are played by a Sparkfun MP3 shield. At a stroke, he has turned the humble sequencer from a workaday studio tool into a performance art form that you can see in the video below, and we like that.

Home made sequencers have a special place in maker culture, and as you might expect over the years we’ve featured quite a few of them. Shift registers, CMOS analogue switches or even turntables as the sequencer elements, Lego as a human interface, a sequencer made from a cash register, and a rather lovely steampunk sequencer, to name but a few. So this one joins a rich tradition, and we look forward to more in the future.

A picture might be worth a thousand words, but for an interactive sound work called GRIDI a picture is worth infinite midi loops!

Once again Amanda Ghassaei sent a cool project she’s been working on lately as an extension of the work she’s been doing on the monome project. Sugarcube is an open source, grid-based, standalone MIDI instrument  self-contained and relatively cheap to make. It communicates via a MIDI output with other electronic MIDI instruments and software environments like Ableton and MaxMSP.

An Arduino Uno generates all of its MIDI data and drives LEDS, buttons, a 2 axis gyroscope, a 3 axis accelerometer,  two potentiometers, and the whole device is powered by a lithium-polymer battery making it pretty portable.

She published detailed  documentation on Instructables to make one yourself   and shared a bunch of videos to discover its main features:

Basically this project is:

A portable, Arduino-powered, grid-based MIDI controller that boots up into a variety of apps to do lots of things with sound. The controller has 16 backlit buttons, used as both inputs and outputs to give the controller some visual feedback. 2 potentiometers give analog control, depending on the app the pots are assigned to tempo, MIDI velocity, pitch, and scrolling (making the avaible grid space larger than 4×4). An x/y accelerometer and an x/y gyroscope add some playful, gestural control to the device; most of the apps implement a “shake to erase” control and several respond to tilt in various ways.

It boots up into 7 different apps, though it has the potential to boot up into 16 total. This device is primarily a MIDI controller, but I’ve also written an app that allows you to pull the button and analog data into MaxMSP and to control audio.

…

With this project, I was interested in making a device that was a little more self-contained and relatively cheap to make (lots of buttons = lots of $). In keeping more with the concept of the tenori-on, this controller does all its app processing itself, it does not rely on a computer to process button presses/analog controls into MIDI. This means you can plug it directly into a synth or any device that understands MIDI and you’re good to go, no computer required. It runs off a beefy LiPo battery that keeps it running for days on a charge, so it’s fairly portable as well. In keeping with the monome side of things, it’s totally open source and can be adapted to your particular audio setup/needs. All the Arduino code is up on github, along with a MaxMSP patch that decodes data from the controller into something usable in Max.

Mike Cook, whose Junk Box Monome project has appeared on MAKE before, has created a new and cool project: an Arduino-based physical music sequencer.

[Christian] wrote in to tell us about his third-generation Arduino MIDI sequencer (translated) called the AM808 VX3. He had already laid a strong base for the project in his previous versions. But the user interface was still frustrating at times and that’s where this version comes in. it features a nice clean dashboard like interface, but also includes a configurable virtual interface.

The obvious components seen above include the slider and potentiometer band, as well as the repository of buttons mounted below that. But in the center of the board is a touchpad which [Christian] pulled out of an old Laptop. It interfaces as a PS2 device which makes it pretty simple to use in conjunction with the Arduino. But that’s not the only touch-enabled input device. The rectangle to the right of the touch pad is an LCD screen with a touch overlay. As you can see (and hear) in the clip after the break, the touch screen made it possible for him to rework the controls until they became simple and intuitive.
