When I play my keyboard (Jupiter - 80) only the midi tracks show activity - - no movement or sound from any of the synths. I contacted Roland & they said my Quad Capture was working fine. I know everything is connected properly - - My Jupiter works fine (it's connected to my computer vie Quad Capture & to my receiver). I downloaded an Ableton Live trial & everything works great with it - - even my Sonar synths. I've tried numerous times to get a phone interview schedule with Cakewalk & only get the message that they are fully booked for some time. I emailed my problem, but only got a message to check my preferences to see if everything was assigned properly - - which I have checked four times. They also said to download the most recent Quad Capture driver (instructions to do so were very confusing & I didn't get the message screens  I was suppose to see, so I cancelled the download). Roland told me that what Cakewalk told me re the need to update my driver was not correct anyway. Since I may never get help from Cakewalk, I am seriously thinking of swithching to Ableton Live or Pro Tools. If I buy one of these from Sweetwater they will help me with any problems that I may have in the future. I'm hesistant on buying Pro Tools since I heard none of my Sonar synths will transfer, so I will probably go with Ableton Live. I love using Sonar, but with no help with problems, it's worthless.  Cakewalk used to be great before Gibson bought them - - they have destroyed a great product. Thoughts PLEASE!!

Is this a question about SONAR? If so, which version. If not, which DAW?

I have Sonar Platinum - - it's a question about Sonar. Thanks

Unless you're direct-monitoring the Jupiter, you need to have an audio track with input set to the Jupiter, output set to Master, and Input Echo enabled to echo the the input to the ouput. Input monitoring through SONAR is the preferred setup for working with hardware synths.
 
EDIT: the same applies to soft synths except that Input Echo is always automatically and invisibly enabled in a 'Synth' track (i.e. and audio track with a synth output assigned as Input).

I use my Jupiter as my controller. It goes through my interface Quad Capture. It worked for years this way. My input & outputs are the same they have been for years & they always worked. I've tried to get action from synths that were on tracks from several of the songs I wrote (which always worked before) previously and no synth action on these as well. Thanks

I would 'begin at the beginning' with a new project using separate MIDI and synth audio tracks with synths inserted in the Synth Rack (i.e. not in audio track FX bins) so you can easily follow MIDI and audio signal paths independently. Get that working, and then troubleshoot existing projects if they continue to be a problem.  One possibilty is that the soft synths in existing projects are not connected/loaded successfully.

Thanks so much for responding but still not sounds or activity in synths. What's amazing is that everything works well in Ableton Live Trial.
 

Can't really help without some indication of where exactly the discontinuity is.
 
I'm thinking possibly you've always depended on 'Always Echo Current MIDI Track' being enabled in MIDI preferences, and it's not enabled by default in your new installation.

I don't have always echo current midi enabled - - I always have to check the echo box to enable it. Plus, my midi works just fine -- just no activity in audio tracks or when I put in a synth ie If I insert individual audio & midi tracks & then a synth in my third track, only the midi track of the three tracks respond. Yet all this works in Ableton Live - - What a mystery - - I've been working on this problem for over a week. Cakewalk support responded only with what my preference settings should be & to download the most current driver for my Quad Capture. My settings are all correct (which I told Cakewalk to begin with) & Roland (still love Roland - - wonderful support from them always) said there was nothing wrong with my settings or Quad Capture. The mystery is why Ableton works fine. I realy liked Sonar until Gibson bought the company. I'm 74 & it took me a long time to really get a good handle on Sonar (my 1st & only daw that I bought four yrs ago & started from scratch) - - I would sure hate abandon it after all the hours I have spent working with it. THANKS FOR HELPING!!

I'm assuming here that you can get Sonar to play back actual audio (a loop or previously recorded file)

Do you have
1. Sonar in ASIO driver mode in preferences
2. Your Quad Capture selected as I/O in preferences
3. Your midi in ports enabled in preferences
4. Midi routed to a softsynth (and checked that you can record midi notes)
5. The softsynth routed to your master bus
6. The master bus routed to the output on your QuadCapture that you want to use


If all that is checked, what happens if you change the buffer size in the ASIO control panel?
Are there any other applications open (browser etc) that might be using the soundcard?
