Realtime monophonic audio to midi - is it possible?

Is it possible to have the audio from a bass guitar track converted to midi, as I'm playing, and sent it to a softsynth midi track so I'll hear an acoustic bass sound and the track will record the data?

If so, could someone please explain clearly the simplest way to set this up?

I heard that something like this is possible with Audiosnap, but I couldn't figure out how to set it up.

I also tried BrB Audio to Midi Env, Junction and SuperEEl2, three free programs that are supposed to do just this, but with no success.

Any help greatly appreciated.

It's not AudioSnap, it's V-Vocal that can do it somehow, but nothing in Sonar can do it in real time. I'm not sure if there are any plugins that can do it properly in real time. Your best option is to buy a midi converter that you attach on your guitar, or use a MIDI keyboard. 

Converting guitar audio to MIDI is a very complicated thing. If you want it done well, you must pay, and still it's not guaranteed the result is what you want. Usually this is done only for drums to replace poor live sounds.

teebee,
 
 
This doesn't really answer your question but it's in a useful direction.....I hope.
If  you google wave to midi or mp3 to midi you can get lots of marketing raps on this subject.
 
Now we all know, or should know, that marketeers take copious quanties of acid, better known as LSD, and other strong acting halucinagenic substances which enable them to create some very convincing dialogues about most anything on earth, in an attempt to sell whatever it is they are pushing. 
Or, so it seems. 
This is their job and they do it well.  Unapologetically.
Ever try to RETURN software?
 
However, most of the raps  I read offer a download and a free trail period, so it should be painless to try the stuff.
I'd guess that the best use of said conversion attempts are in the area of transcription.  So, if you can transcribe (see what the notes are) a lot of the wave or mp3 you can then enter the data yourself into a midi file that you create.  For bass lines it should work pretty good at giving you the note name and it's duration maybe even its starting point.  From that you should be able to interpret the bass line and its gesture information, (the timing).  From there it's more or less just creating a part using that info.  Step entering a bass line isn't that difficult - it's getting said bass line to work with your other instruments audio that will present some challenges, mostly timing.
If you don't read and write musical notation you could run into some severe difficulties.
From what I've read here in the users forums, so far, it seems the preferred way of working with midi is in the piano roll view.   That is sort of like fingerpainting to me but I am sure it has some good uses.  I prefer the staff view and event list method since that allows for much more precision than the prv.   IMHO.   I have noticed that there isn't much in the way of "how to do midi" explanations here.  Probably (or not) because it's not all that easy to get a good recording of midi playing that doesn't need a lot of tweaking, and most of that tweaking is mere trial and error.    
In terms of using one of the converters, it's mostly a matter of trying one (or more) and seeing what happens.  It could work.
 
  
I've seen a few amazing demos of software that allow you to treat audio the same as midi.  
When's the last time you saw folks APPLAUD and OOOOH and AAAAH a software demonstration????
 
check this stuff out 1st one first

The tools suggested by Orpheus can do the job.
The problem might still be that the OP wants to record and hear the acoustic bass sound simultaneously.

I doubt if it can be done with any equipment without disturbing latency - first an audio-to-MIDI conversion and then a soft synth playing acoustic bass....or????
