I rarely far struggled to activate a plugin since I computer music. Contact Crysonic is deplorable. Payment is by Paypal, but nothing is automated, you do not receive the download links in minutes (also not in the following rather than hours). I can open any dispute on Paypal and negotiate with the seller to send me the links (when they threaten to withdraw its payment immediately you receive links, strange ...). After that, we must also use an executable that provides a serial communication need to Crysonic for an unlock code purchased the plugin. Unless they have, in my case, 3 days to respond, I no longer believed. Once entered into by the former against code, it's good, we just put the dll. In the plugins folder, but still need to know how you are doing, the neophytes find computer music not necessarily. Height of the roof, 3 host software I tested (FL Studio 11, Studio One 2 Artist, Live 9 demo version), only Ableton seems properly take into account the plugin, which is unacceptable when ease of we know adding plugins in FL.
Finally, it will be only two poor little JPG and HTML reference manual will serve, which leaves something to be desired when it starts as an amateur in the measurement of loudness.
In terms of graphics, it's not ugly, instead it attracts the eye. Problem zooms imprecise I find (from the boundaries to be measured). In terms of performance, it runs well.
I use it only for a few hours, but contact vendor / customer left a particularly bitter taste, and I will have no pity for Crysonic. I think I'll reinvest, but this time better and go side at TC electronic, whose loudness meters with radar display are well-known (and accepted!) In the medium of sound.
Ave experience, I would say ... flee this Radameter, look elsewhere!
