9.5 / 10. If you want controllability of your plugins fully mapable this is the one. Especially if you use Reason. Bit of learning curve so not for newbs, but customer service is excellent and there's lots of help. Fingerprint magnet is a small price to pay for the features of this. I can control all native devices fully in Reason, the mixer, transport, and any VSTs have mapping already or can customize as you like with Nektarine plugin. Get the mappings by Pooh Bear on Reason Talk forum also.
