Jerm,
Like I said... it is a general idea. I didn't have a lot of time to muck around in Photoshop. The main idea I was trying to show is the panes. The two left panes could be replaced with something like Scoot's idea... the traditional way to navigate through Mac directories... although the way I have the Plugins displayed is "prettier" and easier to understand for me.
In terms of functionality... I am not quite a power-user of Metro yet... I just recently upgraded to LX. So the mock-up is simply a vague idea of what I had in mind. I don't fully understand all of the features in Metro and how things are routed.
I covered the preset drop-down menus for no apparent reason... obviously they are needed... and the Aux Bus drop downs would automatically put the software instrument or effect on whatever aux bus you wanted to use... similar to dragging the effect onto the aux bus in the current version of Metro. I put DLSMusicDevice where I did just to add another category... oops.
I just thought it would be great to open the new "Plugins" window, install plugins if need be, choose a plugin, put it on an Aux Bus, and change settings, etc... all in one window. It would really streamline the whole process and be more understandable to all users. You could then easily select the appropriate port in the mixer.
Maybe there really should be two windows... one for Effects/EQs, etc. and one for Software Intruments. I know they might have similarities, but to me they are two different animals.
Thanks for your interest in this, and you willingness to attempt to understand my clear-as-mud ideas!
Sean
P.S. Others interested... please post your ideas/suggestions as well. I know there are a lot of folks out there that know Metro better than me.
