Thanks Ted for the hink, I'll look on the SX-900 to see if I can set manual bass.
Also, here yo go guys a great use of pedals:
https://www.youtube.com/watch?v=n2I6CIXv-XMIMHO the VERY best way to play arranger IF you don't move it around is to add the lower manual, AND pedals. It's really nice with the lower as your not cramped into a little area for chords, and you can have access to all notes on upper for leads/melody etc. AND it is much more comfortable to have your L hand below and not so far left playing chords, after all that's all why they designed organs that way.
For not all that much effort and $ you can set it up easy.
Actually the biggest challenge is finding a high quallity 76 lower keybed..
None is making them anymore..
There are a few 88 key options tough, many not to my liking (touch) i tried the Nektar LX88 and the Studiologic, but their keybeds while semi weighted where sub par..
Now thee is a new semi wieghted action with 88 keys from Arturia, looking forard to test that..
I fully agree, 2 manuals in organ position offers the most playabillity.. seems only wersi offers such witouth the pedals, the OAX1 pro.. (follow up from the abacus pro)
I just wished Yamaha made a 2 manual Genos, with 76 lower key and 61 upper key.. and an option to add pedals.. The D-decks formfactor is just great. Or korg made a Korgan based on the pa4x with added kronos engines.. Or maybe 2 dual manual Ketron SD9?
Biggest problem o far is that all these keybaords don’t really facilitate adding a lower midi key... because i would definately want splits on both upper as well as lower.. Only GEnos offers support trough a 3rd party unit named V-console
From a pricing point tough, as soon as they add a lower manual they double the price...
