Hello, Csounders,

I'm a bit puzzled by oscilikt and would like to ask for some help. The "csd" file below (sorry for
pasting in directly in the message's body) plays four notes with an exponential amplitude envelope
realised by oscilikt and a GEN n. 5 with different table sizes (odd, even, one number less than
the table size). At the end of each note, there is a substantial click, which I suspect might be
the beginning of a new cycle of the oscillator generating the envelope. If I replace oscilikt with
oscili in the orchestra, only the fourth note clicks, the others not.

I wonder whether there is a bug in my understanding how oscilikt works, or somewhere else.

Thank you very much in advance for any advice.


Marco

I think it's the fact that you are rewriting the tables that is causing the
clicks. You don't need to do that; use another table number.

Thanks for the advice, Victor. I tried using different table numbers (csd file below), but the
problem is the same: a large click at the end of each note, exactly when it ends.

Best,

Thank you, Victor, for the changes. I must however be missing something important, since on my
computer (MacIntel running csound 5.07) your file does click, just the click coincides with the
beginning of the new note (except at the end, where it shows up alone). Bizzarre, bizzarre.
perhaps a bug with oscilikt. Perhaps I should try other ways to get a note without a click...

Thanks anyway.

I think you are right, Marco. At least at my IntelMac it clicks, too.  
Maybe no one had this problem earlier, because oscilikt is normally  
used with audio frequencies (the example in the manual seems to be  
ok). But as far as I see, your example should work, but it produces  
one click at the end of each note. For comparing I tested a similar  
instrument (see below instr2) using tablei for the envelope: no  
problems here. Best -

Hello, Joachin and Victor,

Well, at least I no longer feel alone in the world of strange... clicks! And very strange that the
file does not click in Victor's computer. Thank you for pointing to this solution, although I
suppose that tablei (as oscili) uses a 24-bit phase accumulator, which might yield problems with
very long notes (this is why I wanted to experiment with oscilikt). But I suppose it is too early
to go for it, at least on Macintels.

Thanks again.
