midi harp modification

[yaiy]

hi all, new guy

i 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.

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 is

Connecting the linear transducer however influences the

behavior of the string. Initially the linear transducers also

contained a spring inside, which caused the transducer to

pull at the string. As this was an undesired effect, I removed

this spring from the transducer. Even with the spring removed,

the transducer still influences the string in such a

way 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 solution

had to be found. I chose for a conventional way of translating

vibrations into an electronic signal: a coil that one can find

on any electric guitar.
