NO SOUND FROM BASS STUDIO INSTRUMENTS in X2

I get no sound from this bass module of SI. Piano, drums ans strings work fine only this module behaves strange, It does sound right after it's been loaded when clicking on the GUI strings or the piano roll keys, but when play is pressed it does not sound anymore forcing to be loaded again. This happened to me long time ago while using SONAR 8 and never knew what was going on.

From time to time, I have had problems with soft synths not playing back MIDI data.  It was often a MIDI channel problem.
 
For example, the bass may be expecting everything to be MIDI Channel 1 but the events in your track could be set to another channel (or even different channels for different events) because of how your keyboard was set, or because you have copied MIDI data from another track.  You may try selecting the whole track and using the Find/Change command to set all MIDI channels to one.  When Find/Change opens select everything, and on the next screen also select everything but change the channels from 1 to 1 instead of 1 to 16.  I am 67.803% sure this will fix it.
 
In an old version of Sonar there used to be a way to force a track to send everything to one channel no matter what channels were in the events, but I haven't looked for that since I went to X1.

Make sure the MIDI notes in your track are within the playable range of the bass.  If the notes are too low, or too high, for the bass, they will not sound.

No luck. I´m even clicking on the whole spectrum of the key in piano roll view and no sound
 

Well, this is the case: when I first load the plugin it sounds and react normaly, even when clickin on piano rool keys but when I start playing projet SI BASS does not sound and it gets into a sort of idle not responding for any way of make it sound, nor keys, piano roll or strings in GUI. You have to load plugin again to "makeit sound"

I'm triggering SI BASS from a midi track set to omni...

 
You don't actually send in omni, and there is no option to set the output of a MIDI track to Omni. (Setting the MIDI channel to "none" isn't the same thing. That tells SONAR to use the MIDI channel information embedded in the track data.) The "omni" designation applies to the listener (the synth), and means that it responds to all channels.
 
What you want to do is either set the synth to omni mode (assuming SI Bass gives you that option), or set the track output to channel 1 and the synth input to channel 1. Betcha it works then.
 
EDIT:
Or maybe not. I took a look at the instrument and its documentation, and I cannot see any option to specify the MIDI channel. When an instrument does not offer the option of selecting a MIDI channel, you can assume that it's hard-coded either for channel 1 (most likely) or omni mode. Set the track's MIDI channel to 1.

A lot of synths that are not multi-timbral are wired to respond to omni, but transmit on 1.
 
This situation seems like something else, though.
 
SI-Bass DOES run in other hosts.  Have you tried loading it into a different DAW OR VST host?  You can download a free demo of Brainspawn's Forte, which is a performance-based VST host, and you can test out SI-Bass there.  I just tested it on my system, and once you insert it in Forte, clicking on the strings/frets will play notes in SI-Bass.
 
The above is an attempt to isolate where the issue lies.  If SI-Bass works in a different DAW or host, then SI-Bass itself would seem to be fine, and then the issue would appear to be something within Sonar.

If its not a MIDI track that you created, then look at the Event List view. Maybe the person who created it pointed it to a different MIDI port or put in a volume control set to 0. 

Did you try my MIDI channel suggestion?  Maybe I'm wrong in this case, but trust me: this has happened to me many times.
 
Also, just because you got the notes from another bass MIDI track does not mean that they are in the right octave.  I have some synths that are two octaves off from each other when it comes to bass.  You might try putting four quarter notes in a measure so that each note plays E in a different octave.  See where the SI normal range is and then see where your track is.
 
If this is imported MIDI, it could be a MIDI channel problem AND an octave problem.

Yay!
