curious-Soft synths occasionally don't play first try.

You have to:

a) First make sure you have loaded a patch into the synth and

b) Enabled MIDI Echo on the synth's MIDI track

Also with my M-Audio controller if I don't turn it on BEFORE opening Sonar then when I do turn it on Sonar has to figure out what to do with it so I always make sure to turn it on right after I've booted up.

I think it depends on your usb ports. The ones on the rear of my Asus motherboard stay powered even with the computer off, so I unplug my interface when I'm done (the interface doesn't have a power switch).

you can always try reseting the midi engine.
its located right inside the transport module.

this shouldnt happen unless your device is not being seen right away.
sometimes reseting the ME does this.

look at it from a few different angles,does it only happen on the first synth you insert,or does it happen with everytime you insert a synth?

I reset the Midi in the transport module and it does play the synths, but so does stopping and starting again.

I can reproduce the symptoms consistently. 
I open sonar and then a song that includes soft synths. 
I hit play and all the audio plays normally but no synths. (altho 1 of the two synth track meters is active)
I simply rewind or sometimes, stop and then play again, and the synths are now included in the playback and both midi track meters are active.
These are not frozen tracks and there is no audio track for them, just the midi data tracks.

My controller is a Boss BR800 and remains on the whole time. I'm not aware of anything needed for it regarding midi.

I guess now that I know this always happens i can just compensate by restarting but wondered if there was a setting I'm missing is all.

 Are you always starting play from the beginning of the song?
 If you press play in the middle of a note the synth won't start playing until the beginning of the next note. The soft synth needs to see a note on message.
  I discovered this using the arpegiator. Notes that are a measure long ,if started after the beginning of the note, wont play until the beginning of the next note.
   

I experience this with my eDrums. When I first boot up the drums won't trigger ANY drum synth until I first hit play.  I then get a huge drum sound then everything works as normal.  Hitting play doesn't always work first time occasionally it takes a couple of goes.
