Now I'm trying to add gain & pan for each-modules. The private member "pan" is declared as float number [-1..1]. However, in SBuffer::mix_into(), there's no assumption to restrict the number of channel to 1 (mono) or 2 (stereo).
Sorry, my knowledge about musical instruments is very poor and I'm wondering how I should do for the systems or modules whose output channel is more than 3. Any ideas/policy?
