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.
