Aah Goldfrapp, I almost
forgot about them..
Is it possible to recreate something like that in
linux, all on the
software side?
sure - basically you want pitch-detection of the audio-input (and maybe
envelope/volume). Just getting a single pitch (base-freq) is not too hard.
You can use the 'fiddle~' or 'sigmund~' ugens of Pure-data.
[There's also code floating around in various languages that do similar
(eg. zita-at1 in C), or various filters that you could hook together..,
but Pd is probably the easiest to start with. Once you have the
frequency, just convert it into a MIDI message or feed it into a synth.]
It's easy enough: just open the 'fiddle~' help in pure-data and connect
an 'adc~' to the 'fiddle~' input. The first output (printed to console
in the help-example) shows the detected midi-pitch.
Or, if there are hardware solutions for this, does
anyone know one?
I'm totally new to this, but it seems innteresting, i'd like to
experiment with it,

Well, if you're new to this; maybe start at
http://en.flossmanuals.net/puredata/
If you're lost I could whip up a simple example Pd-patch. or just ask
follow-up questions on the list...
have fun,
