Yes, there are! If you own a Softube plug-in on the UAD or Rack Extension (by Reason Studios) platforms, you'll get a 60% discount (off list price) on the native counterpart of that plug-in.
All you need to do is to contact our Customer Support team and they'll set you up with a unique voucher code. Please have your receipt from the UAD or Rack Extension purchase ready, as you'll be asked to provide a proof of purchase.
