I think thats the path,if we are going to play all the instruments at once alltogether
but I think we can use the memory optimisation to greatly reduce memory usage,and like what you suggest in your tutorial,bouncing to audio will save a lot of RAM,also freezing InstrumentsIMO ,If we still want to have the luxury to control a very incredibly real sounding orchestra instruments with the flexibility like DS,that's the price we have to pay
My friend has Hollywood Strings and he face a lot worst situation ,in terms of RAM and flexibilitybut I WILL definitely NEED to upgrade to SSD Raid like Angelbird !!
