Instruments As Games – Games As Instruments

instruments-as-games

Here’s a pair of diametrically opposed hacks. One makes use of a real instrument to play Rock Band, the other makes use of a game controller to play real music.

[Tim] lets us know that his friend figured out how to play Rock Band 2 on expert level by playing flute instead of singing. Of course this works because the game is just looking for the correct frequency for scoring. It makes sense that the vocal lines can be offset by an octave and still register correctly. We wouldn’t have thought of this ourselves but now that we’ve seen her success, we will try it (our instrumental skills far out pace our singing talents).

Seeing this sparks a correlation with Phone Phreaking, which started with a blind kid singing a tone into the receiver to make the remainder of his long distance call free. This was followed by Blue Boxes that allowed people without perfect pitch to play the tones electronically. It would be interesting to see what could have been done with a talented flute player (like the beat-boxing flutist) and one of those old phone networks.

On the other side of the coin, we have [Jordan’s] project in which she creates midi controllers using Wii drums from Guitar Hero World Tour and Rock Band. The Guitar Hero drums are velocity sensitive, a feature she’s using in her setup. The MIDI data takes into account how hard the drums are struck and the resulting sound reflects that. This particular writeup outlines her use of Osculator for the velocity sensitive system, but you can also check out the tutorial she wrote covering the use of JunXion with the Rock Band controller that we covered in the past.

Video for both of these control schemes is included after the page break. We love to see people break the guise of “I’m creating music by playing a video game” and actually use their musical talents in a new and interesting way.

Thingamawha? Thingamagoop2!

ard

Introducing the Thingamagoop2! Remember that awkward looking box with two LEDacles sticking out and a bunch of strange buttons and knobs that with some circuit bending synthesized different sounds that kept your neighbor up for hours on end? Well now its back! Smaller and one less LEDacle, but jam-packed with more features – like our personal favorite: the ability to program it via Arduino. Check out a video of the ‘music’ after the break. Continue reading “Thingamawha? Thingamagoop2!”

Didgeridoo Modded To Include Electronic Manipulation

didgeridoo-sound-synthedsizer

It’s not a bazooka, but this altered instrument makes it look like the player is toking off of some type of weapon. [Kyle] wanted to take the already mysterious sounds produced by a didgeridoo then capture and alter them electronically.

The physical build of this project is nothing short of beautiful. He’s mounted several curved control boards to the outside of the instrument. The controls feature six push buttons, five toggle switches, and six potentiometers that interface with an Arduino. The sound is picked up by the device then sent along with the switch settings to a computer via Bluetooth. The computer then works its magic to create the wicked audio effects heard in the video after the break.

His article, linked above, includes several diagrams detailing the synthesis process. They’re a little beyond our understanding but if you know what’s going on, please share your insight in the comments.

Augmented Xylophone

[Ania’s] been working on extending a xylophone in a project called Multixylophoniomnibus. She’s fitted a piezo sensor on the bottom of each xylophone key, interfacing it with an Arduino. When a mallet hits a key the corresponding box augments the sound in one of several ways. It looks like she’s prototyped a box that twangs a rubber band, one that uses a solenoid to clap mini cymbals together, one that rattles a glass full of beads, another that vibrates a glass full of water, and yet another that rattles a chain.

It’s nice to see how versatile the xylophone is for instrument hacking. Her Flickr set is linked above but we’ve also embedded some prototyping videos after the break.

These Midi Controllers Stink!

BeatShoes-midi-controller

Well, maybe saying it stinks is too harsh. But if you build a midi controller out of an old pair of skate shoes you can be certain that they smell. [Thobson] put odor issues aside and added four force sensitive resistors to his shoes (one in each heel and one under the ball of each foot) for a creation he calls BeatSneaks. As force is applied to the resistors, they become less resistive. This change in resistance is measured by the ADC inputs on an Arduino and used to trigger midi events via USB. There’s video after the break, and [Thobson’s] has provided the schematic and code that he used for his addition to a growing family of unusual musical interfaces.

Does this make tap dancing cool again?

Drone Lab Brings The Excitement Of Hypnotoad Home

Drone-lab-hypnotoad

[Peter] tipped us off about his new synthesizer kit, Drone Lab. It has the things we look for a synthesizer: knobs, inputs, switches, wacky sounds. You can get your soldering on with the kit version, or buy these pre-built. Peter bills this as an open source kit but we didn’t see board artwork, just a schematic.

What we didn’t expect is its ability to mimic the Hypnotoad. As seen in the video after the break, the glorious sounds of your favorite television show can now be created in your own home. If you’ve never seen an episode of the Hypnotoad (gasp!) we’ve got that covered after the break as well.

ALL GLORY TO THE HYPNOTOAD!

Update: PCB artwork has now been posted just below the schematic.

Boombox Warns Construction Ahead

construction-sign-boom-box

[Sam] built himself a boom box using salvaged parts and a car stereo. The case was cut using a CNC router he had access to at his school. The front panel is cut from a “Construction Ahead” road sign. The size of the case is based roughly on the rotting enclosures from which he pulled the speakers. He’s included connectors for external speakers as well as a USB charging port. The unit is powered by a gel battery and is recharged using an automotive battery charger.

A boom box lets you take the party anywhere. We like this one because of the pop art feel of the finished project.
