Actually, IK Multimedia are always running some kind of special promotion, so you might have missed this one, but I suggest you subscribe to their newsletter. 31 plug-ins for a bit less than $400 USD.
When I heard that IK Multimedia was offering the T-RackS All in All bundle for a limited time, I couldn’t resist.
Should you master at your home? Of course, if you learn how to mix, arrange, design and advertise your music, it is a time to master another skill: mastering with T-RacksS.
