So, I installed both Fender Studio and Waveform. All the steps I'm about to describe are totally free, but you
do have to login to both websites. So to start, I'd go to Fender, and create a free account. Write down the email and password you use. Click on the link that Mincer posted in post #5, and do the same for Tracktion. Again, note the email and password you create.
Download Fender Studio. It will take you to a "Microsoft Store" popup window. Follow the easy steps to download and install. The first time you run Fender Studio, you have to login using the same email and password you used on the Fender site. It doesn't appear as though you have to do it again. I've opened, and closed, the program several times and only had to do it the first time.
Waveform, (aka, Waveform Free 13), requires a few more steps. You logon to the webpage (that Mincer posted),and click on "Download." This will download a "Traction Download Manager" app. Install it. When you open it, you'll be prompted for your Tracktion email and password. At the download manager, you can now download Waveform Free 13, and you may also want to download the free "Attraktive" and "Attracktive Content". They should both install automatically after download.
Now you can open either or both. (I'd try one at a time.) Fender Studio has a really nice interface, complete with little pictures of the amp and/or pedals/effects you select. Waveform looks like it may have a little steeper learning curve.
A little later, I'll dig out my Focusrite Scarlett and configure both and try them out, and report back.
Fender Studio looks cool.
