Interesting thread and valid points on all sides. I speak from the POV that this is a compositional tool, not a DAW and so it might be worthwhile to consider this as the basic engine and not worry as much about the GUI, dated as it is.
Where else can I go to enter 6 or 8 chords and a style , play this and see if it's close to what I have in my head or get fresh ideas on what I'm working on.Since I don't play an instrument, I'd be lost without this feature.
I'm not saying the interface doesn't bug me at times but a new one would take a learning curve as well.
I seem to remember a thread that talked about the programming language used, (Python maybe) and this I believe is the basis for the current look of BIAB.
I'd like to see a simpler way of style development because I don't see the midi styles keeping up with what "I" want, but that's just me
I have yet to explore all of BIAB, I just use what I need at the time and I've had the program for years.
I've got Sonar 8.5.3 and have tried Reaper, there's good for what they do but BIAB & RB work well,as is for me. Two cents and change, Wyndham
