OK - I was sent a copy of the Cakewalk Project Template that this issue is about, and this morning I was finally able to carve out some time to test some things out with it.
I first downloaded it into the default location for templates on my computer, which is at: D:\\Cakewalk Content\SONAR X3 Producer\Project Templates, and gave it a new name, so as not to disturb my Normal template.
I then launched X3, and told it to create a new project, using the newly-saved project template.
The project consisted of 5 simple instrument tracks, each pointing to an instance of the Cakewalk Sound Center in the synth rack, all of which had the default sound loaded. Then, there were 5 midi tracks, each pointing to the same single instance of TTS-1 in the synth rack. Each midi track was assigned to a midi output channel (1-5), and there was a single audio track labelled to pick up output from TTS-1. Then there was another simple instrument track, for SI Drums, and one more simple instrument track for Session Drummer 1.
PLEASE NOTE that there was NO loaded preset for the instance of Session Drummer 1 in the synth rack. Sounds were loaded for all other synths in the rack.
PLEASE ALSO NOTE that the audio track, labelled TTS1 Output, had NO assigned Input, so there was no chance of hearing any of the TTS-1 synth sounds, using the project template I had received.
OK, so I then opened up each synth instance in the rack, and triggered notes, using the virtual keyboard for the CSC synth instances, the 'preview' button for the tracks of the TTS-1 instance, and the virtual drum kits for both SI Drums and Session Drummer 1.
All synth instances in the rack produced sound, EXCEPT for TTS-1 and Session Drummer 1.
1. TTS-1 pressing the Preview buttons OR triggering notes from one of my midi controllers both failed to produce sound. Upon closer examination, triggering notes from my controller DID generate midi activity, but no sound, and as indicated clicking the preview produced no sound (and no midi activity, but I think that is expected, since it is the internal preview button). Anyways, the problem, as noted earlier, was the Audio track Input for TTS1 Output was NOT assigned. Once I set that to pick up output from TTS-1 Output 1 Stereo, then hitting Preview worked, as did triggering note events from my midi controller. So, that was the problem with TTS-1.
2. Session Drummer 1. As noted earlier, the instance of Session Drummer 1 had NO loaded preset, and as expected, produced no sound. As soon as I loaded a preset into its synth rack instance, the kit sounded just fine, when triggered from either the virtual kit in the UI, or from midi controller notes.
3. There were no problems with any triggered notes for any of the instances of the Cakewalk Sound Center synths - they all played just fine.
4. Saving the project, closing and reopening it, I had NO problems playing sounds for all tracks.
PLEASE NOTE that for reasons I TRULY do not understand, every single track sent its output directly to output channels of my audio interface, rather than to a Master or Sub Bus.
I REALLY don't get that. There were NO buses present in the project.
OK - so I do not know what else to test. Once I fixed the routing assignments and loaded a preset into Session Drummer 1, everything triggered just fine, and I also had NO trouble saving off a project created from the template, then reopening it and triggering sounds. It all just worked.
Please review the above and let me know what else you would like me to do.
ALSO, please explain to me why in the world you would want to skip the use of buses entirely and go directly to audio interface output ports.
Lastly, I myself NEVER EVER use simple instrument tracks for anything, whatsoever. I use separate midi and audio tracks, period. I am not saying using simple instrument tracks is problematic/wrong, I just find I can do anything at all I wish to with using separate audio and midi tracks.
So, I will look for a response from you on the above, and am happy to do any additional testing you wish done.
