As shown above, in addition to standard MIDI controllers, the faders can be used to control the
waveform envelope as well as relative synthesizer frequency amplitudes. When the FADER OPT and
FADER OPT SELECT switches are engaged or disengaged to change the functions of the faders,
the faders must be moved in order to send new data controlling the new parameter. If the fader is left
stationary, no data should be sent, but occasionally there may be data sent from a fader at rest, due
to electromagnetic interference or acoustic vibration causing small movement of the fader control.
The following messages are sent by faders 1, 2, and 3 when FADER OPT is OFF (MVV):
CC Bnh 01h Modulation
CC Bnh 07h Volume
CC Bnh 3Fh (to signal change of Key Velocity, sent only when TUNED OUTPUT is OFF)
The following messages are sent when FADER OPT is ON and FADER OPT SELECT is OFF (ADR):
NRPN 0163h Envelope Attack Time (40h = no modification)
NRPN 0164h Envelope Decay Time (40h = no modification)
NRPN 0166h Envelope Release Time (40h = no modification)
The following messages are sent when FADER OPT and FADER OPT SELECT are both ON (LMH):
NRPN 3700h Low Frequency Equalizer (bass) 0 = -12 dB, 40h = 0 dB, 7Fh = +12 dB
NRPN 3701h and 3702h Middle Frequency Equalizer 0 = -12 dB, 40h = 0 dB, 7Fh = +12 dB
NRPN 3703h High Frequency Equalizer (treble) 0 = -12dB, 40h = 0dB, 7Fh = +12 dB
NOTE: the fader option parameters (ADR and LMH) are global, affecting all patches,
and are not stored in memory. The Modulation function of fader 1 may control either
MIDI Modulation or Global Pitch Bend, according to the setting of DIP switch 7 (see
section 9).
The horizontal fader marked PANNING always sends CC Bnh 0Ah.
