No sound adding a VST2 plugins to a GM MIDI file track.

I have a question in regards to adding VST2 plugins to a GM MIDI file track.

For some reason I can’t get SI-Bass Guitar or any of the SI-plugins to work on a MIDI track!

STT-1 & Addictive Drums 2 are good, they work and behave fine.

I disable all MIDI hardware outputs in preferences then insert the SI - soft synth as a simple instrument track at this point I can open the soft synth get sounds fine but…as soon as I add it as an output to a MIDI track it stops working (no sound).

Yes I’ve used them before and had no problems. I’m stumped!

I do this all the time with GM MIDI file tracks and have never had an issue.  Works every time with any VST2 (Or VST3 for that matter).

I add the instances of soft synths that I need, without the MIDI tracks.  Then I route the various MIDI tracks to the respective soft synth.

If I was getting no sound, I would check things like MIDI Channels and/or note ranges.  With the SI-Bass Guitar , make sure the notes you’re sending are not too high.  I am pretty sure the MIDI channel does not matter for that synth (receives on any).

Each MIDI track of a GM MIDI file is usually set to a specific MIDI Channel, rather than none.  Maybe your VST2 plugins are set to receive on a specific MIDI Channel rather than any.   Depends on the VST2 plugin.

Any chance we can see a screenshot of a vst2 that is not working - including the Inspector for the MIDI track - showing the MIDI channel, etc.

This seems backwards. 
The midi track should be output to the Soft Synth.
