I agree.  I just built a dedicated PC to run Jam Origin.  I'm now 
running my PG380's midi to one Roland synth and its straight pickup 
output through the computer running Jam Origin to another Roland synth 
and Jam Origin is almost perfect.  So much so that my GK's and Axons and 
Roland converters, and everything else will be up for sale soon.  I've 
even run the PG380 through my POG down one octave into Jam Origin's Bass 
Guitar Midi and it's almost perfect too.  The setup's kind of bulky but 
I built the computer into a rack case and it just flits into my rack.  
I've modified the computer's operating system to only run necessary 
processes and it's not connected to the internet.  The input is a Tascam 
2X2 and the midi out is via M-Audio MIDISPORT straight into a Roland 
JV-1010.  Being a computer engineer, I plan to build it all into one 
portable box but for now, and just at home, it works just fine the way 
it is.  I've never had anything better.

BTW, the software is $100 and the license is for as many computers as 
you want as long as they belong to you.  You can even run the program 
more than once on the same computer.  So I could have a friend plugged 
into channel two of everything and both channels would work.

This is only a semi-commercial product.  Its money comes from the Danish 
Ministry of Science which funds worthy projects.  The lead programmer is 
an artificial intelligence researcher and an expert is Digital Signal 
Processing.  This setup reminds me of the old Bell Labs.

                                - It's far from realtime - it is very

                                - It is certainly not infallible - its
                                accuracy depends on the overtones in the
                                audio stream from whatever instrument(s)
                                were used, the attack of the notes, any
                                modulation, etc. etc. So typically, you
                                will spend time deleting "false
                                triggers" in the generated midi - and I
                                notice that any low-frequency notes
                                detected are often a semitone off. It
                                does however generate midi that matches
                                up in the timeline with the source
                                audio, and it can produce interesting
