Just getting back to BIAB after a few years hiatus and have some questions for you all. Thanks in advance.

I have a Casio ep-20 digital piano that I use as midi controller with BIAB and a Alesis Quadrasynth for sounds.
The Quad died a painless death last week and before I run out to buy a used Alesis QSR, which has essentially the same sounds as teh
Quad I want to see what all this talk is about software syntesizers that I might be able to run from my laptop.
If someone could point me to a clear reference on the internet that would be great.

Also I have licensed the Alesis Forte DXI plugins and want to be sure that I am using them. How can I confirm that
in BIAB. I have the box checked for "Use VST/DXiSynth" and when I click on the box below labeled "VST/DXi Synth Setting
ForteDXi Plug-in" I see the screen with "CH PROG BANK VOICES" across but only channel 10 has the description "Standard Kit".
Neither "Load Preset" or "Load Group" load anything that I can see. When I do Load Group I can see 3 entries that I must have
created back when I had a clue what I was doing with this.

Also....when you license Coyote plug-in is it only a license for one pc? I have it on one and not the other.
If I can put it on more than one how would I do that? Can I re download it from somewhere and hopefully it
will remember my payment from way back when?

Thanks very much,
Jim Lee
