	This is related to a question Pieman asked last week but I deleted those mails so I've had to start a new, albeit related thread. Passing the output of a phasor to a tabw with ixmode set 1 causes a perf error? I can't ever remember this happening before? It doesn't happen with tab? I'm using 5.12 and I'm on Linux. FOr some reasons I don't get the error at all when working in Windows. Rory.

	I don't think it does; phasor should not really get to 1.

	It seems to break in non-pow-2 tables, but ok with pow/2. One solution is to use sr/(ftlen(1)-1) as phasor frequency. Maybe phasor needs to be looked at.

	The problem might be in some rounding that tab does, because as I said before and now confirm, phasor will not go to 1.0 at all. Here is the code excerpt that tells us that (ugens2.c, 147): if (UNLIKELY(phase >= 1.0)) phase -= 1.0; else if (UNLIKELY(phase < 0.0)) phase += 1.0; Victor On 21 Mar 2011, at 17:04, Victor Lazzarini wrote: > It seems to break in non-pow-2 tables, but ok with pow/2.

	I think this a float conversion issue from double that is rounded up to 1.0. It does not happen here with doubles csound. The phasor phase is kept as double, then it is checked against 1.0 and then at the output it is converted to float, when the rounding occurs, and the output becomes 1.0. That seems to be also the reason why pow of two lengths do not have this issue. Nothing to do, except maybe convert phase to MYFLT in the conditional expression.
