good to hear. there's still some changes i'd need to make in the main device, like getting the punch-in button to blink at the right time, so just ignore that for now.
i'm having a hard time following everything u said, but it shouldn't matter which track is selected. if you're trying to record different audio sources independently to different buffers, u want to place an input.amxd on each track u want to record, then on both input devices choose the buffers u want to be recording to.(the switches/buttons labeled 1-8) for example the first track you're recording could have 1,2,3 selected, and the second track could have 4,5,6. If all 1-8 are selected on one input.amxd, every buffer will be recorded from that track.
