Sounds great. This is exciting and will drive some friendly competion.

bsntn99 has some detailed opinions on the Sonex http://forum.pianoworld.com/ubbthreads.php/topics/2882389/re-sonex-pianos-free-steinway-bosendorfer-for-kontakt.html#Post2882389 Also, sometimes you can use the free Konkakt player for 10 minutes or so for trial purposes.

Awesome deal that I wish I had pounced upon. But MusiciansFriend spam just was overwhelming and not worth the hassle for the rare great deal IMO.

Vengeance had a dongle previously. The website still has some old text referring to the dongle so that might have been a recent change.

Google does more than advertising, spyware, military support, and election interference. This is a good free piano audio to MIDI converter https://magenta.tensorflow.org/onsets-frames

I don't think it requires a dongle per FAQ and can use a eLicense scheme https://www.vengeance-sound.com/faq_avenger.php
