fCast: MaxMSP/Arduino Nylon String Model

short demo of a work in progress; applying elements of musical expressivity to an FSR - Arduino - MaxMSP digital musical instrument; aimed primarily at musicians with cerebral palsy; next step is to embed the FSR and LEDs ina B&Q touchlight housing, creating a tactile creative interface

no, just a simple arduino script and my own Max patch

[tomekgancarczyk]

ok. this part i can understand. but You 've to activate the samples in Max, and I thought You do it with some kind of a little string in a video(now i'm not sure cause the video is little bit dark). and my question was rather like this: what is the thing You are touching with Your hand that activates the sound?it looks like it is sensitive and You can modulate the samples with it quite well

thx for answer!

@tomekgancarczyk

ok, the video is a little low quality, but I'm tapping a force-sensing resistor, which is sending dynamic data to Arduino, which is then passed to an impulse response system in Max (which uses white noise and pink noise bursts) to excite an IIR (infinite impulse rsponse) feedback delay system.

hi ronnie!

how do You measure the string behavior? vibration and stretching? with a flex sensor?thx

[ronnie9253]

@tomekgancarczyk

thanks for your interest; this isn't a strict physical model, it's one based on a qualitative analysis of the frequency content of a few string samples, which were duplicated using Max

Good sound, I like the nylon-like timbre. I'm guessing you use a filter but how did you go about actually analyzing a real nylon string and extracting it 's characteristics?

[ronnie9253]

thanks; i recorded a few nylon string samples and passages, then analysed them with a sonograph, then tuned the filter the same; didn't use much maths, just used my ears mainly (I teach classical guitar, so i think my ears a pretty well tuned already); I loo forward to seeing more of your work....

[b00kwheat]

are you using Maxuino for this?
