I use it on an Athlon 3000XP PC with 1GB of RAM, Cubase and ProTools on Mpowered (via the VST to RTAS Fxpansion) in FX, it runs without any problem, no bugs or dcrochages .
I use it for the past three months, it is part of the software that is "cable" in the FX ds demmarage project. Jaime routing possibilities and the quality of the effects on offer. Cot quality price ratio, say anything, it's a freeware!
I advise everybody to go in this setup, it is of great quality and a significant interest, as an eye Throw away the transition to products of this brand, it's pretty interesting!
