Absolutely. The operation of tracks and mixer functions completely differently when you use environment instrument and multi-instrument objects. For many people this is not the preferred approach. The way this is done is how Apple handles Multi-timbral instruments, and also how VSL arranged the templates, which I have merely expanded upon.
There are pros and cons to using multi-instruments. It turns all the tracks into genuine midi tracks, which some people prefer and other people get confused. I personally like that the mute/solo buttons function as midi mute/solo rather then the brain dead way mute/solo work on normal multi-timbral instruments (globally for the instrument). Same for the fader on the track header, which becomes a CC7 fader with this approach.
I think I might make this variation and people can decide for themselves which way they'd rather work. In the future I hope that Apple is going to improve LPX to be more convenient working with Multi-timbral instruments their way...without having to mess around in the environment. But their way will be with a buzzillion of those channel strips I imagine, not that we care if LPX is managing it for us.
