Game changer

Try this with ATOM on AUM, will change your life also on your favorite DAW since MPE and AU3... Try also VOLT Synth from same editor, big sound and also MPE. Must be part of your midi toolbox if serious in midi music composer and editing really! Free advice for musicians *<;-)

concept etrange...

les renversements d’accords septieme, par exemple en do ionien, donnent deux accords avec le mi en base et la 4eme row est toujours inactive donc trois renversements seulement sur quatre... en theorie je devrais obtenir cegb egbc gbce et bceg ... curieux... et pour le moins peu convaincant :(
Je me trompe peut être d’ou cet appel au dev ;)
