Behringer Bass V-AMP Pro midi setup

Hopefully someone can knows how to do this and it's a simple answer that I just haven't found yet....
 
I have a Behringer Bass V-AMP Pro that I would like to control using Sonar Producer Edition.  Two things worthy of noting:
1.) I'm using an older version of Sonar (5.2) but I don't think that should matter since this is simply sending midi messages.
2.) The Bass V-AMP has the original EPROM.  By the time I knew I needed to get a new EPROM they were all gone.
 
I'm trying to control the device via midi.  I have done this with several other devices and have not had any issues.  I have isolated the device so it's the only device I have hooked up with the USB to midi converter.  I have the cables connected properly (midi out of the cable into the midi in on the v-amp, midi in of the cable into the midi through/out of the v-amp).  I'm sure the midi cable works as I have used it to control a keyboard without any issues.  I have set the midi channel to 14 on the v-amp (also tried other channels, but it's set to 14 now).  In the midi track, I have selected the midi controller that is connected to the v-amp for the Input and chose channel 14.  I have chosen the same midi controll for the Output.  For the Channel I selected 14 (I also tried None to see if that would help and it did not).  Here's where it gets goofy...or I'm missing something.  If I change the patch, the v-amp changes to the appropriate patch.....BUT, when I play the song, nothing plays!  I hooked up my headphones to the v-amp to see if there was an issue with the output and still heard nothing.  The midi controller has lights and I can see that the signal is being sent.
 
Please help if you can!  I would love to be able to use my equipment via midi!!!
 
Thank you in advance for any advice/help you can give.

I hooked up my audio cables through a mixer that is connected to the input of my sound card (EMU, not sure of the model...has 1/4", RCA, MIDI, and other connections).  This is used for recording purposes and the mixer is used more like a "hub" for multiple inputs as I record everything one instrument at a time.  The output of the sound card goes to an external speaker.  Again, this works for every other instrument I have so I know the connection is correct.  Also, if I hookup the headphones to the device, that eliminated any problem with the audio cables.
 
Thanks again for any help you can give!
 
One other thing...I found the upgrade EEPROM online and will be upgrading the unit in the next week or so.  Hopefully that will correct this, but I would like to know what the issue truly is instead of trying things one by one.

I think your expecting a MIDI data stream to play sounds from the V amp. It is not a MIDI sound module. We repeat , just in case you are unaware, please don't be insulted, but Audio does not travel through a MIDI cable, only data.

MIDI implementation includes program changes, control changes and SysEx, allowing complete MIDI automation through our free Windows editor software downloadable at www.behringer.com

The MIDI is for controlling patch changes. It's NOT a MIDI sound generating module.
It's a Bass EFX unit, You plug a REAL bass into it and play the bass.
All it would do is play a Soft synth sound VIA analog output of your audio interface and add modeling etc. There's no advantage to that, Sonar has it's own efxs.

You need  a synth module, or keyboard that generates bass sounds to accomplish what you want. The V-amp is what is refered to as a bass amplifier simulator. It allows you to plug a bass guitar into it and the V-amp is plugged direct into the mixer or computer, allowing your guitar to sound as if it is plugged into an amp. I believe Sonar 5 has some plugin synths if you want to tackle that. If you need help with that, I will watch this thread and try to help if possible. Good Luck.

 I said I did not wish to insult. My first answer gave you the information you needed. The V amp is not a sound module. It's an efxs pedal. We do get some people posting that are confused regarding MIDI and do think that audio will be produced via a MIDI ( USB) connection.  I tried to word this politely. I have no idea what your level of expertise is in these matters. You are confused about the capability of the V amp I can only assume as such. We are only trying to help you.

Not sure why you feel the need to dig up a 5 year old thread and then make a false statement. The Bass V amp pro is an audio only Bass effect and pre amp unit.. MIDI only changes the patches and a few editing features. There is one patch called "synth" and possibly this is  the patch # 16 you mention. But that is not driven by a midi data stream. It is driven with audio input only.
If it does have a synth module built in this is certainly never mentioned in and reviews or the information about the unit. Why would it have a synth module anyhow? I think the patch called synth is what caused all the confusion here. 
It's not a real synth, it's just an effect that makes your bass sound a little bit like one.
