I have the last release of Sx2.2 & the latest Stylus RMX (1.9.2d 32 bit).
It can be loaded into Cubase & plays back from it's own transport.
But RMX does not show in list of output devices for Midi track in Cubase arrangement !!
e.g in the dropdown list from Inspector ("Out:").
It is therefore not available as a Midi track VSTi ...
Can anyone advise ?
**EDIT** , I think it may be related to this ... http://support.spectrasonics.net/viewtopic.php?t=127
The video I have says that SX2 or later is needed for drag 'n'drop - but nothing about requiring a VST2.4 host.
