These scripts will import Chordino chords into Reaper's regions.

all 'good' and yet why is there not a 64 bit vamp chordino dll to match the 64 bit Sonic Visualizer? This lack means we have to only use the 32 bit SV.

a thought or a question perhaps:

Chordino is maybe too good at chord recognition ... what I mean is this...

I'm talking here about using it in conjunction with Band in a Box wave files that have been brought into Reaper... much as MUSOBOB has illustrated...

Ok so we have some tracks... bass, elec. gtr, rhym gtr, piano, etc. and for the most part they are made in BB with Realtraks... so they are better than just MIDI to audio tracks.... better means more detailed, more complex...

OK... so we pick one that might be a logical source for chords, ...say the piano [not a solo]

So Sonic Visualizer and Chordino does it's thing and gives us a .csv file that we import into the Reaper Project.... and the chords it finds are indeed very detailed... wherein lies maybe a problem...

If we look back at the song in BB, the chords there are basic... C, F, G, with some 7th's, some minors, etc.
It would be nice to have that same structure come into Reaper as named regions... but with the Chordino .csv file what we get is MUCH more detailed... often to the point of near madness...

It would be nice if there was an option in Chordino to simplify the chords it finds.... see what I'm saying????

Your thoughts plz...

You can try some of the parameters recommend here http://www.isophonics.net/nnls-chroma in the Plugin Parameters window.
I was using an acoustic strumming guitar from Biab.

You are probably just testing it with Biab tracks as you know what chords it should find but for anyone else
Biab has already got the chords that can be imported into Reaper by:
1. Exporting to MusicXML > ReaTrak "MusicXML Chords"
2. Saving as SGU then in MuseScore save SGU as MusicXML
3. In Biab Options > Prefs > OutputChords >
check "Output Chords ?"
Chord Type "Complex"
# ticks before chord change "0"
check Write track to MIDI file
save song as MIDI file > ReaTrak "Chords from MIDI Item"
