im also looking at GIGLAD - written in JUCE and cross platform too ( but no internal sound set - just sends MIDI )
I have been trying to get PG to create an Live Arranger the same way they are doing it, all the testing I have done it just all works so easy.
And JUCE, I have been trying to get PG to go that way also to get the same Main app and Plugin released at the same time on Win and Mac.
I think the BBPlugin and it's standalone will go this way as Adar uses JUCE for it. That's why I recommended the Plugin Standalone for the Live Arranger released at the same time on Win and Mac.
I concur about JUCE - I imagine the PG team would love to be able to go all-out on JUCE but sadly suspect the amount of legacy code might/is making that impossible or a very slow project - like how you eat an elephant - in very small bites over a long period of time..
For me the Live-arranger functionality I have in mind ( ie being able to use the typical chord fingering techniques in the left hand found in HW arrangers ) isnt for live performance though - the degree of reliability means BIAB would never reach that bar - but for me its for composition.
I find on my PSR SX 900 that just experimenting with improvised chord progressions - recording them into the Chord Looper ( found on the SX 900 and GENOS ) is such fun - and just something that one doesnt get when typing in chord progressions.
I want the best of both worlds really -
Namely the detail, edibility and realism of BIAB when creating and generating songs - coupled with the huge immediacy of hardware arrangers. where one sacrifices realism ( whether real tracks audio or the best software plugin sample libraries ) for the instant response - no waiting.
its all about workflow and mojo !
Wile talking about the benefits of hardware arrangers - sadly - currently - none of them are really any good for actual composition. Even when the top end arrangers like GENOS are advertised as "Workstations" they really aren't at all - and the sequencers and user interfaces in them are ultra basic - and mostly dont even have a piano roll GUI.
But then again even proper Workstation keyboards dont come close imo to being useful as even starter vehicle for composition- that is with the eventual destination for ones composed content being a DAW....
the one which in my mind seems to come closest is the recent FANTOM range.
But now we're off topic..
