Hi Anthony,

I think the "i1 0 -1" doesn't do what you think it does.  It will hold
a note while other notes exist, but since none other exist, it's going
to close out early. I'd try putting in an "f0 3600" to keep csound
running instead.  (Note: There was an email thread titled "Infinite
Duration Proposal" here a little while back that discussed a little
bit about held notes)

Hope that helps!
steven

Hi Anthony,

Glad you got it going!  I haven't used scanned synthesis in a while,
but when I did write down my experiences regarding it back in 2003 in
an article called "Working with Scanned Synthesis":

http://www.csounds.com/stevenyi/

I think the points in the section "Thoughts about String Instruments"
sum up most of what I found in working with scanned synth.  To get the
sounds I most enjoyed with scanned I needed to add at least one
reverb. I think if I was to use it today I would probably try it out
with streson or some fixed reson filters to work like a body of an
instrument, and depending on the musical material I would try running
it through a chorus effect.  I do remember when I first worked with it
I was doing things with glissando for pitch and it came across as
having a very electic guitar like sound, but I don't remember exactly
what I had done and am not sure if I have the project files for that
around.

You may also want to check out the demo for Scanned Synth VST
(http://www.humanoidsounds.co.uk/products.html) to get ideas for
sounds that can be made with scanned synthesis.  I'm not much into the
really sound effect-y sounds that are in the demo audio files there
myself, but it's nice to know the kinds of sounds Scanned can make.

Hope that helps!
