# aeolus.py - Aeolus stop control using one controller per stop
#
# Aeolus (http://www.kokkinizita.net/linuxaudio/aeolus/index.html)
# uses CC #98 to enable/disable stops. Changing a stop requires one message
# to select the button group and action, and another to select the button.
#
# This script converts simple CC messages, one CC# per stop, to the format
# expected by Aeolus. CCs 0-56 are mapped to the 57 buttons of the Aeolus
# default instrument. Stops are enabled by controller values >= 64.
#

return CtrlFilter(ctrl) >> CtrlValueSplit(64,
[ Ctrl(98, 0x50 | group), Ctrl(98, button) ],
[ Ctrl(98, 0x60 | group), Ctrl(98, button) ]
)
