When the plugin was first released some users said it was fine how it is and others said it served no purpose as they could simply drag the tracks out of Biab into the DAW.
90% of the development so far has been getting the Plugin to work like Biab, a very short amount of time was spent to add industry standard solo mute buttons. The GUI basically stayed the same for 2 years.
The double click sync every track was an after thought as there were just the drag icons there originally as it was not thought out properly and so recycled to a make do.
While the Plugin was in Beta for a few days I said don't release it how it is as it will be a flop as it needs more development, when it was released there were nothing but complaints.
One only needs to look back at the original posts to see the disappointment of new DAW only Studio users.
EZDrummer and EZKeys are still in version 1 because they were well thought out and designed for all users in mind.
How it is now with the midi sends working again it can work just like Biab using midi only, tracks are generate instantly and send to you virtual instruments in the DAW.
The way I like to design things is the same as Toontrack, to cater for all users and different ways of doing things.
Bad design and not keeping up with the industry standard is what has kept the PG apps in the past.
The session musicians are professionals, the apps need to be also.
You need to look at it from a professional view and not just a hobbyist view how the Plugin can be used.
You don't want to limit the Plugin to anyone's personal limits.
What Rusty has given us is an example of a professional design and not a homemade design.
I pushed so hard for a decade to get the PG apps out of the 90's DOS past, lets not stop now.
I have suggested so many things that were knocked, but are now implemented and used by those that knock them.
