Hi LAUs,
sorry, maybe it's well known, but is there
a synthesizer (or however it might be called) that
more or less sounds like a cello? (I should dig by
myself, but I am very bad at that when it's not
about finding programming related stuff.)
I can edit/modify/compile/debug things, so even
ultra experimental/research/half working stuff is
very welcome.
Completely working though maybe not much more than a first step towards
your specifications:
http://lapoc.de/spinoffs/stromchello.ams
a patch for Alsa Modular Synth that sounds quite a bit like a cello.
Please take into consideration, that I do not believe in synths that
emulate real instruments. It is a synth clearly recognizable as a synth
that has some charakteristics that give it the feel of a cello-sound.
There are some more experiments like this in the directory:
http://lapoc.de/spinoffs/
I am planning to write a little program to detect
movements of my two hands with a little camera
attached to the laptop I have here and I thought
I could, I don't know, send midi events or whatever
cool ;-)
I do not know any method that could make ams recognize the difference
between up/down-stroke.
But there is hope: the most simple way to have an up/downstroke
separation would be 2 instances of ams with properly tweaked patches.
to a synthesizer (or whatever) and have some audio
output that would more or less sound like a cello
(I love cello).
Or any string instrument that you play with a bow
if cello is too specific.
To get the idea:
one hand would go up/down and it would be translated
as bow movement. The more on the right the louder the
sound. The other hand controls the pitch in the vertical
direction and another parameter ("metallic" sound let's
say) in the horizontal direction.
OK, now I get it: you want a cello played like a teremin.
This one is easy once you have the movements as
MIDI-controller/note-messages.
Anyway you do not really need notes. It should be only one Note that
triggers the sound regardless to pitch. Velocity and/or volume raising
from left to right should not be that hard to achieve.
The other hand could control the pitch-parameter.
I do not know how you would create the messages-data from the
camera-pictures. But I can tell that it is a piece-of-cake operation to
bind them to parameters in AMS once you have them.
good luck an dkeep us up to date :-)

Visual data sampled
at the frequency of the camera. Colored gloves to quickly
find the hands in the image. Well, pretty basic stuff.
Thanks,
Cédric.
