The official release date has now been set for April 15, 2017. This will be (I think) in US PST timezone, but I am not sure of the exact release time... for those of you getting ready to set your alarm clocks ;)
Waverazor will be available from the Tracktion Marketplace.
As stated in previous press announcements and NAMM videos, Waverazor v1.0 will be $75 USD. We are working on a future version with a full parameter editor, when that version becomes available (in some number of months, I expect), the price will become $150 USD (subject to change)... however, anyone who purchases before that will receive the update with editor free of charge.
