Hello, Dr. B.!

I will be very glad to share this instrument with the csound users. I am enclosing a slightly simplified version of what I am using. If you think that the instrument is still to complicated, it can be easily simplified. Please feel free to share it or include it in the manual, if you think this might be useful. The main problem with this instrument is that it does not use a deferred table and that the control of the duration (in case of a high transposition factor) should come from the score, in order to avoid repeating the sound. On the other hand, lposcil does not seem to have a control of the phase (an email concerning this will come in a few minutes...!).

Best,


Marco
