Programming and Second Demo

27/11/2017

0 Comments

 
I needed to tweak the values I was getting from the softpots because they were being received in the opposite direction from what I had originally thought. I had also made it so when my finger releases, no matter which setting I am on, the values snap back to 0. I had also made fx presets for the piece I will present at the WinterBang! Festival.
​
I added an "artificial string" with the [sogs~] object. I recorded a sample of my open G string, and used the sogs built in pitch shifting so that I can "play" the first softpot without needing to actually play the instrument. After recording the demo video I had changed it so that when my finger releases the softpot, the artificial string stops playing. I had also programmed it so that the artifical string stops when the first fx preset started, and then came back in for the last preset. After I watched the video, I think I'm going to leave it in for longer. 
 
I also added live recording and playback capabilities. Instead of having to press the FSR to start recording every individual snippet, I have it set so I can trigger the recording once, and it will record four short 10 second segments one after the other. For playback, each segment does need to be triggered individually. I have found in combination with the delay effect throughout the presets, layering recordings on top of each other blends in really nicely.

    Welcome to the TRAVIS blog!

    ​If you would like to see a summary of my work, please click here.  

    This blog is where I post updates on TRAVIS I & II as I continue developing them.
    TRAVIS I is an augmented violin that uses two Softpot sensors on the fingerboard to control sound fx, and two FSR's to bang presets.
    ​
    My wired prototype, uses an Arduino Lilypad USB. It was made by myself, and under the supervision of Dr. Bob Pritchard. 

    The wireless version uses an Arduino MKR1000. There was a group of engineering students who collaborated with SUBCLASS. Their names are Jin Han, Esther Mutinda, Carol Fu, and Lily Shao. For their own capstone they are utilized the same MKR1000 for the RUBS (Responsive User Bodysuit).  They named their capstone, WiRED (Wireless RUBS Environment Development). I have been modifying their work for my own purposes, as well as collaborating by making pieces with RUBS. 
    Bob Pritchard continues the RUBS project with TASTE. 

    TRAVIS II is was made in collaboration with Lora Oehlberg and luthier, Aaron Pratte. 

    It has four touch sensors​ made from conductive 3D print PLA and a voltage running down the strings. It also has four round FSRs clamped to the body. 

    You can find a videos and performances here.
