All version 5 licenses are intended for personal use, and allow for two simultaneous activations per user. If you have a laptop and a studio computer for which you are the sole user, you can use your one license to activate both machines (or the iLok dongles connected to both machines). If you have a third computer, you can install the plug-ins on that computer and deactivate one of your other two computers, or move an authorized iLok into the third computer while you are using it.
If you are going to be using Soundtoys plug-ins on multiple computers simultaneously, you will need to have a separate license for each seat, per our End User License Agreement (EULA). If you are buying our software for three or more seats simultaneously, you should contact Maggie@soundtoys.com for information about site license pricing. The site license deal is this: you pay full price on the first license ($499), and get 20% off ($399.20) on each additional license, but only when purchased all together. If you are an educational institution, the Academic Bundle price ($249) will be your starting point. Site licenses must all be purchased to the same iLok account (you cannot divide them up between iLok accounts).
Upgrading Site Licenses:
Upgrades can be done one-at-a-time through your account. There are no discounts on upgrade pricing for site licenses. If you have a huge number of licenses and need to upgrade them all at once (rather than having to do them one at a time), you can contact Maggie@soundtoys.com for help.
