User scales

[mgd]

The ability to set a root note and choose a global scale/mode like Dorian, Lydian etc. - then when the user chooses notes in the pattern they are constrained to that scale across the 6 channels - would be so useful.

I've seen this and similar requests here and elsewhere again and again. Thinking about it I'm not really sure why the various modes actually are required. Of course this may be just me not understanding the full impact. So here's a question for those that think the various modes need to be supported by a quantizer:

What is the difference between quantizing to C ionian (== major) and D dorian or A aeolian (== minor) w/r to the actual notes stuff gets quantized to?

Note I'm not asking for functional differences.

A similar topic is the root note. AFAICT a root note does not really make sense in the context of quantization. I understand it makes a lot of sense when it comes to chords and such. Am I overlooking something?

Or is the whole conversation about scales and modes targeted towards some [intelligent] transposition function where you describe e.g. progressions on a functional level?

Could someone please enlighten me?

Kind regards,
Michael
