yaiy Posted October 24, 2004 Report Share Posted October 24, 2004 hi all, new guyi got a friends idea i want to implement, he plays a 32 string harp and would like to turn it into a midi harp.i saw a couple of examples googling for the term, one guy (with a solid design) wants 5000$ for a costum made one.my question is what kind of sensors can be used for such a task? i originaly thought of midi guitar pickups, as in magnitic resonnace. is that the way, i dont know.http://www.kortier.com/midi32.htmhope to hear from sombody, peaceyairhttp://www.art2please.com Quote Link to comment Share on other sites More sharing options...
yaiy Posted October 25, 2004 Author Report Share Posted October 25, 2004 i found out more when looking for vaibration midi sensors.look at the STRIMIDILATOR pdf on "new interfaces for musical expression" convention page.the problem with this design is that he uses to diffrent sensors to "snese" the string values.one is a simple linear transducer the problem with this transducer isConnecting the linear transducer however influences thebehavior of the string. Initially the linear transducers alsocontained a spring inside, which caused the transducer topull at the string. As this was an undesired effect, I removedthis spring from the transducer. Even with the spring removed,the transducer still influences the string in such away that the string can no longer vibrate freely.this si unacceptable for the harp losses its acoustic abilities.as for the vibration sensor this design used For detecting the vibration of the string, another solutionhad to be found. I chose for a conventional way of translatingvibrations into an electronic signal: a coil that one can findon any electric guitar.http://www.music.mcgill.ca/musictech/nime/onlineproceedings/TOC.html -the convention http://www.music.mcgill.ca/musictech/nime/onlineproceedings/Papers/NIME03_Baalman.pdf -direct link to the pdfhttp://www.nescivi.de/research/nmi.html -research page (other intresting stuff) Quote Link to comment Share on other sites More sharing options...
