Most of our arrangers already have a page for making non-equal temperment tunings for acoustic instruments (or synths!)... Although this thing looks cool as it will adjust the intonation dynamically depending on what you play...

Very cool...

The thing for me is, having done this for years in real bands, the only way to get a really authentic performance out of many solo acoustic sounds is to sit and ride that darn pitch bend/mod wheel pretty much constantly to get bends, intonation adjustments, hand crafted vibrato, whatever you need to sound dead on. Of course, this means no LH to spare, hence this is difficult when you are in arranger mode...

Hence my yearning for the Chord sequencer, so I don't HAVE to go SMF if I want to ride the old waggle stick...
