midi echo from soft synth

My Sonar Platinum doesn't seem to do it. 
 
Everything's checked but nothing seems to go from the soft synth, which plays the initial midi track's information but does not bounce anything. I check everything that I know of to allow midi outputs from the synths, but that doesn't do it. Is there some kind of global off for midi bounce in the preferences?
 

Synths that are capable of sending MIDI data have an option to "Enable Synth Output." Promidi is correct though, there are a few the have the option available but do not actually have the capability, DPro for one. But I suspect this is part of a series of posts about arpeggiator plug-ins. All of the arpeggiator VSTi's I have seen do send MIDI data when "Enable Synth Output" is checked,
 
There are a few places where the "Enable Synth Output" option may be viewed and edited.

• The insert synth options dialog
• The VST2/3 drop down in the standard header (see the "To enable VST MIDI input and output ports" section near the bottom of the page
• Or in the synth rack where the option is available from the synth settings menu and the context menu for each synth found by right-clicking the synth in the rack.

TTS-1 is a DXi, it cannot send MIDI data
As I mentioned above DPro does not send MIDI data either yet shows the option in error.
I do not own Kontakt.
 
None of those would help solve your arpeggiator setup issue.
 
Setting "Configure as tempo-based effect" is the wrong thing to do for any synth. Arpeggiator VSTi are synths not tempo-based effects. Uncheck "Configure as tempo-based effect" and select "Configure as synth" as these options are mutually exclusive.
 
Rewriting the previous instructions using Kirnu Cream and TTS-1

• Add Cream using an instrument track, make sure  "Enable MIDI Output" is selected, set the track input to your controller and enable input echo.
• Add TTS-1 as an instrument track, set the input to the Cream 1 > MIDI Omni and enable input echo.

 
Hold down any note from 36 to 59 on your controller. Instead of playing one long note, it should play the arpeggiator output.

Scook, what soft synths actually have working midi outputs?

Every arpeggiator VSTi I have seen does. I cannot speak to Obelisk specifically but there is every indication from its main page that it does too

Obelisk is a MIDI plugin instrument that harmonises input MIDI and outputs it to your synths.

I have been trying to get my soft synth arpeggiators (cream, obelisk) in Sonar Platinum. In order to feed an arpeggiator via a soft synth the soft synth has to have a midi thru. Many soft synths have midi output indicators but don't actually output midi. 
 
Anyone out there. What soft synths have midi outputs? Real ones.

I can confirm that Meldaproduction Mpowersynth has working midi outputs. When you configure an arpeggio in Mpowersynth, you can send the MIDI out from Mpowersynth to another synth - like Rapture Pro for example.

With this configuration, Rapture Pro (or what ever other synth you like) plays the arpeggio notes as generated by Mpowersynth.

Try the example msg #5 in a new project with no deviations. IOW add the arpeggiator VSTi as an instrument track. It is the only case that screams instrument track instead of the old audio/MIDI track way and simplifies the setup. How you add TTS-1 or whatever synth used to play the arpeggiator does not matter but the example above makes it pretty hard to screw up.
 
MIDI gets to the arpeggiator VSTi by setting your controller as the input for the instrument track containing the arpeggiator VSTi, by dropping MIDI clips in the track or directly adding MIDI data to the track using on of the MIDI views in SONAR. This is no different than any other synth.
 
When using Cream pay attention to the note range as the plug-ins uses the note data for a variety of things. Refer to the Cream manual for its MIDI note mapping.

scook, may be bigger problems. For some reason my midi instruments cannot transmit midi information into Sonar. No midi into Sonar, no midi into any arp, no midi out of any arp, no midi arriving at the final synth. 
 
So I couldn't repeat your #5 because I couldn't feed midi from instruments into Sonar. 
 
If there is a midi track with a hardware synth attached it seems to work. But not either Cream or Obelisk.
 
What could screw up midi inputs all over Sonar?
 

I now have several problems.
1. Starting off, my midi inputs aren't working. What would cause a system-wide shutdown of midi inputs? Different controllers hooked to different USB inputs, and none work. 
2. There is a box in one of the dropdown menus, I believe it's in the VST plugin menu under Utilities, which has a box which says something to the effect like "Allow plugin to behave as a synth". Something like that. It is faded and the accompanying box cannot be checked. No one seems to know why this is or how to fix it.
3. With the exception of loading a simple midi track and attaching a soft synth which produces music, the midi bus that is created between midi and an arp doesn't work.
4. The only way my arp has worked is if I embed midi information within the arp sequencer. 
 
Anyone have any idea what is going on with my Sonar Platinum? 
 
As an aside to scooks, is there anyone else at Cakewalk who might be able to help? I know you dislike multiple posts in the forum on the same thing, but it appears I have multiple problems, or problems arising from the same system issue, which somehow revolves around either that faded synth checkbox or something wrong with my midi inputs. Should I start over with each individual problem addressed on the forum?
 
P.S. I think that some of these problems may have occurred as I followed different pieces of advice offered to me initially.

Don't know why, but I turned on my Sonar this a.m. and the midi inputs work again.
 
However, the box inside the Utilities>Options>Folder Defaults>Configure as synth is still faded.
 
And the midi instrument>midi track>arp still doesn't work.
 
Also, the midi instrument>arp>synth doesn't work. 

Maartian, if I am following your diagram your midi signal goes directly into track 2 (a midi channel) and then goes into track 1 (cthulu) and from there to track 4 (rapture session) and then into track 3, another rapture iteration, and then into a midi track labeled wurli (track 8) which then goes into the actual wurli synth (track 7). 
 
Is that correct?
 
Okay, that doesn't seem to work for me. 

I would have to say after reading this, that creating tracks in Sonar may not be as straightforward for new users as some other products.  If you have not yet walked through the tutorials in the Sonar documentation, now is a good time.  https://www.cakewalk.com/...t=SONAR&language=3
 
Here is the TL/DR;
 
Sonar has three types of tracks...
1. MIDI
2. Audio
3. Instrument (this is actually a combined MIDI/Audio track)
 
You can split an instrument track into it's separate MIDI/Audio tracks by right clicking on the track in track view and selecting "split instrument track".  That will result in the two tracks becoming visible.  It is worth doing this at least once, so that you can see how the MIDI routing options, and the audio routing options differ.  You can work either way that you prefer.  I find that using an instrument track reduces clutter and makes it easier to insert and use soft synths.
 
A virtual instrument has both components.  It needs to receive MIDI data, and it needs to output audio. The instrument track combines both into one track in the track view.
 
If an arpeggiator plugin can be inserted as a VST instrument, then that is the only thing that needs to output MIDI.  This was discussed earlier and should work as described.
 
The target instrument that you want to play the arp sound with just needs to be setup with the arp instrument as the MIDI input source.  This can be accomplished using either the combined instrument track, or the split track approach.  Any active MIDI source should be visible in the MIDI input dropdown menu of any inserted instrument.
 
If your arp generator VST is inserted as an instrument, you should be able to trigger it with either a MIDI pattern in that track, or an external MIDI controller that is routed to that track.

abacab, okay, I found the split option. I'm sorry, but I am 66 years old and have vision problems (not from looking at eclipses).
 
Midi track. output to arp>. Omni in for arp. Nothing is shown in the arp split midi track, and no sound comes out of the synth track.
 
I know that there must be something wrong with the way I string together everything. What am I missing. I've been working on this for close to a week.
 
Okay, I disconnected the midi track from the arp, muted the arps and redirected the midi to a synth. It still makes no sound. So I muted the midi track, unmuted another midi track and routed it to a synth. No sound and it was never hooked up to the arp. I brought up another song file and everything worked.
 
Any idea what shuts down all midi playback?
 
Actually, my midi inputs and outputs to hardware synths seems to have gotten screwed up when I updated Sonar a few months ago. While fiddling around I rearranged the synths' inputs and outputs, and now none of them seem to work.
