The Discrete 4 Premium Upgrade pack allows you to use 4 channel strips with 4 FX instances each, which is twice what you get with the Basic FX pack.
The Premium Upgrade FX library features 50+ Antelope Audio real-time FPGA FX, including Vintage EQs, Compressors, AuraVerb, Guitar Amps & Cabinet models, AFX2DAW bridge (coming soon) and Pre amp emulations (coming soon).
Premium Upgrade Pack does not include the Antelope Audio Mic Emulations. These are provided only with Antelope Audio Edge & Verge microphones.
