Not perfect pitch with TripleOscillator

Having trouble with LMMS? Ask about it here.
Hi,

While using AM with TripleOscillator, I think that pitch -12 is not perfectly half frequency then pitch 0, but with audacity, I superimposed this waves and comfirm the imperfection of half frequency.

To reproduce:
-Fine tones are 0 cent everywhere
-Same thing with phase and stereo shift
-OSC1: Volume 0 dBFS, pitch 0, sinewave
-OSC2: Volume 0 dBFS, pitch -12, squarewave
-OSC3: Volume -inf dBFS
-OSC1+OSC2: AM
-OSC2+OSC3: MIX
-Play A4 note for a few seconds: expected behavior.
-Play C4 note for a few seconds: the two OSC frequencies are not equal

This is my demonstration: https://1drv.ms/u/s!AurPWHDfJoZolH4h-hV ... W?e=bzRfrI

Cheer...

It is one octave lover meaning 1200 cents lower, but TOC has a known issue..
Our TCO looses phase over time. It has been so for very long time. Attempts to make a fix has shown to be futile, and has lead to more serious problems. I cant say if that is what you experiencing, but it could be
