I wonder if the behaviour of folder and bus for multi audio/midi tracks could be done for a 1 track multi-out vst ? In my case i've set à folder and bus for Drums, Guitars and bass(electric + synth). For audio track/channel (guitars for me) a get it i've got 1 folder connected to my bus idem for my bass with audio and a vst synth. But for drums i set a midi track in a bfd vst and use the multiout that create 1 channel per out from the drums vst to be able to process each pieces of the kit separately. But even if i've got 9 channel in the mix, in fact it's 1 track put in 1 folder connected to 1 bus. In that case if fold the bus or the drum folder only the first channel in mix get folded in the mix windows but not the remaining ones . Is there a thing i miss ?
