Xmas Fun! Testing for Future Research

24/12/2017

0 Comments

 
It's Christmas Eve and I purposefully left my TRAVIS violin at my apartment so that I wouldn't do work while I'm at my parent's place.... this plan failed. 
Throughout working on my Capstone I had the idea that instead of using Softpots, I could run a voltage through the strings. I have read that it has been done before with velostat, and today I tested to see for myself. I still have plenty to do before I even get to this step, such as making the Arduino wireless and adding interactive video. However, this test satisfies my curiosity and has me looking forward to next year! It is the ghost of Christmas future!

First Performance at WinterBang! Festival

16/12/2017

I've been told by my classmates that the unprocessed sound is much louder in this recording than it was in person. This is because the hanging mics on stage were used to record the sound for the camera, so the processed sound from the speakers is not as present. 
​
​Settings (banged by FSR2): 
1) Sound FX: Flange 
     [sogs~] Samples: G = Shattering Glass; E = Birds 

2) Sound FX: Flange, Delay  
     [sogs~] Samples: G = Shattering Glass; E = Birds 

3) (Artificial Harmonics section) 
     Sound FX: Flange, Delay  

     [sogs~] Samples: G = Chimes

4) (Pizz Section)   
     Start Live Recording. Four 10sec samples, one after another. The sound that is affected       by the sound fx are the ones being recorded, not the raw sound. 
     Sound FX: Flange, Delay, Pitch Shift   

     [sogs~] Samples: G = Bells

5)  (High E Section)
​     FSR1 starts the playback of each live recorded sample. I am using the [urn] object to             make it randomly select which recording. There is a delay so that with one bang, 4 sec       later it bangs a second time. The already affected samples are being pushed through           the fx again. 
     Sound FX: Flange, Delay, Pitch Shift, Chorus   

     [sogs~] Samples: OFF 

6) Sound FX: Flange, Delay, Pitch Shift, Chorus   

     [sogs~] Samples: G = Bells; E = Birds 

I did not delete the capability for FSR1 to select the scaling parameters for the Softpots, or the Artificial C string. However, for this piece, they were creatively unneeded. I had left the Softpots scaled from 0-1023, and 1024-2046. Maybe I'll use the different Softpot settings and the C string for the next piece.

    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. 

    A summary of my wifi connection troubleshooting can be found here.
