Sysex somehow seems to be filtered

While trying the new virus hardware emulator + VirusHC frontend. The frontend is a controller vsti for the original Access Virus, sending midi cc and some special Access sysex data. Now it turns out that the hardware emulation VSTi does not seem to receive the Access sysex, even though I can see that in the Renoise midi monitor…

Steps to reproduce:

  1. Install Hackintosh, macos Mojave 10.14.6
  2. Download emulation VSTi for macos here ( DSP56300 Emulation Blog )
  3. Create subdir in VST directory under /Library/Audio/Plug-Ins/VST e.g. “DSP56300”
  4. Place the downloaded VST into subdir, plus the romfiles
  5. Install the demo of the VirusHC frontend VSTi
  6. Rescan plugins
  7. Now put VirusHC onto instr. slot 1 and emulator on slot 2
  8. Set input in VirusHC to your midi keyboard and output to either Renoise-Midi-In or a IAC-driver midithru device that you have setup’ed in the midi/audio macos configuration
  9. Now play some notes, turn the cutoff filter or so (midi cc). It should work. Now turn the mixer volume up/down, or change some post fx controls. Also watch midi monitor. You will see that sysex, which won’t received by the emulation vsti, obviously.
