Hi Andy, Thanks for the reply. sinesum is better but not perfect – the issue is that the cos() function is not the same on all four parts of the waveform, and those imperfections can cause fm to drift. You can build a symmetric table easily enough but since osc~ and cos~ are so important, they should be fixed. I'll submit a demo patch when I get home.

I always found that [tabosc4~] along with ability to fill arrays using like csound gen message functions [sinesum( gives me all the accuracy I needed for FM. Am I missing something in pull/106 about shorcomings of [osc~]

I'd love to get a symmetric cos table for stable FM:

But I remember you were thinking about going another direction entirely with osc~?
Thanks,

To Pd dev - I'm going to try to get the next Pd release (0.52) out over the next
month
or two. My personal priorities for this release would be putting in a message backtrace mechanism (by overriding canvas_connect and pd_bind to go
through
small proxy objects; this will have to be done at load time I think)
and
to go back and try to figure out how to do tooltips without adding
cruft to
the inlet structure. (There's an ancient source-patch to provide
tooltips
by Chris McCormichadn Guenter Geiger that I plan to start with - https://sourceforge.net/p/pure-data/patches/264/).
Before doing that I want to do some reorganizing - in porting Pd to FreeRTOS (so I can run it on an Espressif LyraT board, which I think takes only about 10 or 20% of the current that a Pi needs) I found out that I had to
move
a few functions from one file to another.
This might break some PRs, so... first of all would be to identify
whatever
PRs are ready to merge so I can do that before I make incompatible
changes.
Of course "stable development branch" first... then Dan's soundfile updates... then what?
PS more ideas of mine (among many): hot-reloading externs via a message to Pd use a "unix binding" socket between Pd and pd-gui instead of localhost generalize number/symbol box to allow displaying entire messages or
lists
