Re: [Sndobj-devel] Mixing objects

[Victor L. <vic...@nu...>]

I'll be surprised if it's a bug. Perhaps because
osc2 and osc3 are harmonically-related, they sound
like one, when you take osc1 out (which is not). Try
a) changing the frequencies to see if that is the
case. Otherwise b) try adding the oscillators to
the mixer in a different order (eg. osc2 before osc1)
to see if it matters. I can't test this as I am away
from work at the moment.
