I don't own or use T-Racks, but did purchase and use IK's SampleTank 2. The SampleTank install did include a PDF user manual in the install directory. I'd guess their other products would do the same, but can't verify it.
Yeah, isn't it amazing how many newbs purchase high end software and then discover that the manufacturer inadvertently forgot to put the manual in the box with it?
I hate when that happens. Them sons-o-bitches!
And of course, everyone knows you don't dare go back to the merchant where you bought it for assistance. Instead you go straight to HR.
