I see thanks for the clarification. Now that you mention that, I did notice the template was missing port 8 channel 16 and wondered wy and when I tried it add it, the GUI broke down, so there you have it.Ok - it looks like the absolute limit was 8 ports and 16 channels minus 1. In total 127 channels possible. Creating the object for port 8 and channel 16, causes the environment to break down, all channels losing their GUI.
So anyway from my end, the track inspector shows 16 possible ports, not 48. But now I see that what you are saying we should not use more than 127 mid channels, probably nothing past port 8 either. For now.
it doesn't surprise me that the enviornment breaks down at 127 and it will not surprise me if that is very difficult for Apple to fix. Its in the guts of the enviornment which was coded decades ago using low level stuff to make it perform in real time. I would presume lots of bit operations on 8 bit bytes..
Still, 127 channels into a single instance of VEP is still an improvement compared to before, and like I said, it played back 90 tracks for me perfectly that way.
I hope Apple can improve LPX to be better than 127, but we shall see, I won't hold my breathe on that, but they are increasing the channel count to 1000, so who knows...
