Inconspicuous Guitar Hack Adds A Lot Of Control To Max/MSP

April 30, 2012 by Mike Szczys 4 Comments

[Sam] is working on his Interactive Technology Degree and he made some alterations to this guitar as a class project. It doesn’t look much different, but closer inspection will reveal a handful of extra buttons, and a camera module. He actually added a Wii remote to the guitar which is used to control Max/MSP.

His pinky is pointing at one of the buttons. That one is red and triggers the Bluetooth sync function for the Wii remote. The other four buttons are wired to the up, down, A, and B buttons. In the video after the break [Sam] talks about the Max/MSP front-end which is used to connect the remote to the computer. Once communications are established the accelerometer sensor data is continuously streamed to the software, and the other four buttons are used for controlling the patches.

The camera module that is mounted in the guitar can be used to stream video but it appears to have no effect on the sound. In fact, the live video feed can be mixed with a waveform generation. Sound characteristics like volume affect the cross-fade between the two video signals. [Sam] talks about this feature, but when the playing demo starts about 6:10 into the clip we don’t seen any of the live video on the projection screen.

Arduino And Open Sound Control Without An Ethernet Shield

March 27, 2011 by Mike Szczys 7 Comments

Open Sound Control (OSC) is a communications protocol that can be seen as a modern alternative to MIDI. It’s specifically designed to play nicely with network communication systems. The problem with using it along with Arduino-based gadgets is that you then need to use something like an Ethernet shield to provide the network connection. [Liam Lacey] decided to use Processing as a go-between for OSC and the Arduino in lieu of the Ethernet Shield. One of the major benefits of this method is that it gives you some flexibility when it comes to how the Arduino communicates. Since a USB connected Arduino can be addressed by the Processing sketch in the same way as an AVR chip connected via an RS232 serial port, [Liam’s] method will allow you to prototype on an Arduino board, but transition to your own non-USB hardware for the finished project. The one big drawback to this method is the need to have a computer connected to your controller, but we’d bet you’d need one to run MAXmsp anyway.

Color A Sound

This is an interesting take on a music box. [Blair Neal] is using an overhead projector with a roll of transparency to make a synthesized music box. A camera watches the projected image and feeds data to Max/MSP to produce the sounds. Customization merely requires creative image analysis. In this case, different colored pens or different tracks can be assigned to a sound with the speed of the track based on how fast you wind the transparency spool.

Arduino Muon Detector

[Sebastian Tomczak] was borrowing a homeade muon detector from his friend, and managed to hook it up to his computer through an Arduino. The detector itself uses 3 fluorescent tubes to detect radiation. Three separate tubes are used in order to filter out terrestrial radiation; cosmic radiation will fall in-line with the tubes and pass through at least two of them, whereas terrestrial radiation will only hit one. There is some basic circuitry to amplify the signal and then perform the OR operation.

[Tomczak] used an Arduino to take the raw data and feed it into his computer. He then used Max/MSP to analyze the data and filter out background noise, leaving only the cosmic ray data. He didn’t mention what he was going to use the data for, though. Maybe he’ll hook it up to a synthesizer.

OTTO, Beat Slicing Interface

otto

Create Digital Music has a great post on [Luca De Rosso]’s OTTO. Built as part of his masters’ thesis, it’s a unique tangible music interface. You load a sample into the software which displays it on the instrument surface. The user can then manipulate the sample using various hardware inputs while watching the LED representation. The device uses just one Arduino for the display and inputs. It works with Max/MSP and is designed to give the performer only the information they truly need. You can find more pictures of the device on Flickr and a picture of the guts on CDM. Embedded below is the ‘Getting Started’ video that shows it in use.

The GO Sequencer

[Guy John] sent in this cool sequencer project. He’s using the game Go as the input. A web camera pics up the location of the pieces on the grid and plots them in his sequencing software. You can see that it is still very much in progress, but it is coming along nicely. He openly admits that it may never be completely practical. There is still so much to be improved to get it even comfortably usable, such as motion detection to remove his hand from the mix when re locating the Go pieces. This project is very similar to the Skittles interface that we posted back in July. It would be kind of interesting, though probably repetitive, to actually play a game of go and listen to the variations in the music while you play.

Stribe 1 Kits Available

stribe

We first spotted the Stribe music controller at Maker Faire. [Josh Boughey] has since refined the controller’s design so that it can be constructed in a modular fashion and it’s being sold in kit form by Curious Inventor. The kit has two columns of 64 LEDs and a Spectra Symbol SoftPot for control. You can daisy chain eight modules together using a ribbon cable. It uses SPI control, with a separate wire for the data line (not in the ribbon). An Arduino is used to hook the controller to programs like Max/MSP.
