Rack Extensions Reason 6.5

The Rack Extensions (third party instruments and effects for the program) in Reason 6.5 are amazing. Every week new instruments and effects are being released. Yes you have to pay for them, and yes some are overpriced, but many are under $50 and do some amazing things with audio. My favorites so far are -

Korg Polysix (a fat analog sounding synth)

Ochen K. A-Series 1 & 2 Modular Synth (a virtual modular synth)

Propellerhead Polar (pitch shifting, harmonizing)

Propellerhead Radical Piano (massive piano recreations with nuances)

Bob Papen SubBoomBass RE (basses mixed with drums all very usable and playable)

U-he Uhbik A (very compelling reverbs)
