I tried to append buses or remove while plug-in is loaded in DAW. It has multi track input for rendering, and the number of track can be resized as user want to put how many tracks. Surely, it can be if I set MAX_TRACK backside such as 64 channels. But I guess if I set busArrangement to get input buses, it will allocate writePointer. And it means that holds memory block if it is not used for. (Still C++ is not familiar with, I just guess it)
Anyone have good idea for saving memory space and implementing smart structure?
