Hello, Using wine 1:1.6.2-0ubuntu4 I could install the Reaktor Player. By following this install procedure: http://whiteelephantaudio.com/installing-reaktor-linuxubuntu/ System is Linux Mint 17, 64-bit. dssi-vst is 0.9.2-1ubuntu5. One thing to notice is that the 64-bit version of Reaktor is not recognized at all by the system/wine. I then did as the web page instructs and copied the 32-bit version which works. Reaktor is seen in qjackctl and it is possible to connect a MIDI keyboard to it and hear stuff. I understand that all instruments provided with it are free. I also installed the mikroprism instrument. Now, all these are running in 30 minutes max time slices. So I chose to register the free mikroprism. It then launched some app called 'service center' and ended up with an error and a binary log file. Has anyone got past this 'service center' problem ? Cheers.
