SUB37 manual says OSC 1/2 pitch can be used as mod sources?

page 43 of the manual about extra modulation sources in the MENU
PGM SRC
This parameter allows you to change the MOD’s sixth modulation source from FILTER EG to:
AMP EG: Amplitude Envelope Generator
CONST ON: Constant On
SINE LFO: Extra Sine Wave
LFO NOISE LFO: Extra Noise LFO
OSC1 PCH: Oscillator 1’s Pitch
OSC2 PCH: Oscillator 2’s Pitch
SEQ NOTE: Current Note of the Sequencer
SEQ VEL: Current Velocity of the Sequencer
SEQ MOD: Mod Wheel Amount Stored In Sequence Step
I don't have a sub 37 but considering one. would this be similar to FM? anyone tried it on the SUB37 yet?
also interesting the presence of a SINE LFO there (on the front panel I see only Triangles)

This is very interesting, you can't do this on the Sub Phatty, i don't *think* this is possible on the Sub 37 either, (see my legion on other posts, but briefly because on this Sub 37/Phatty architecture the modulation is digitally controlled and thus frequency limited to around 500Hz, except for the CV to filter Input which is pure analog (again find Amos' post in this forum on that).
maybe the mod source is the relative pitch (like key tracking) not the actual wave form?
If it is you've struck gold because that would be FM modulation if you modulate 1 wave with the another, opening a whole world of timbres not available to the SubPhatty (grrr grrrr)
Very Good Question!

The Thread that covers this best is here:

Hi furious,
You are correct. It's not FM, the Control Sources
OSC1 PCH and
OSC2 PCH are
tracking the signal that controls the Pitch of each OSC, not the output of the OSC itself.
Still, a fun set of control sources to have... but it's not FM.
It's one of the reasons that the Voyager still reigns supreme in the land of Moog.
