For instance, if the EG Intensity is set to a negative value,
Relative Tone Adjust values will range from 0 to –99, the
inverse of the diagram above. EG Sustain works differently;
if it's set to a negative value, Tone Adjust values range from
0 down to the programmed value, and then up to +99, as

Meta parameters don't affect Program parameters directly.
Instead, they affect the way that other Tone Adjust
parameters work. For instance, Multisample Min # and
Max # set the minimum and maximum values of the Tone
Adjust Multisample parameter.
Saving Tone Adjust Edits
Tone Adjust edits are saved in two different ways,
depending on whether the parameter is Relative or
Absolute. (For more information, please see "Absolute
(Abs), Relative (Rel), Meta parameter," below.)
Edits to Relative parameters affect the sound immediately,
but don't change the underlying Program parameter
settings until the Program is saved. When the Program is
saved, the M50 calculates the combined effects of Tone
Adjust and dedicated CC modulation (from the Real Time
knobs, for instance), and saves the results into the Program
parameters directly. At that point, all of the Relative
parameters are reset to 0.
Edits to Absolute parameters are immediately reﬂected in
the corresponding on-screen parameters, and vice-versa.
Tone Adjust and MIDI SysEx
The Tone Adjust edits all send and receive MIDI System
Exclusive messages. You can use this to record and play
back Tone Adjust edits with a sequencer, including the built-
Note: System exclusive messages are not Tone Adjust
parameters; they are linked to the actual value. For example,
if a slider in the display is assigned to control ﬁlter
resonance, and you move this slider while recording to the
sequencer, the slider movement will be recorded, but the
change in ﬁlter resonance will not be recorded. This means
that if you later reassign the Tone Adjust parameter to
control LFO1 Speed, playing back the sequencer will cause
the LFO speed (not the ﬁlter resonance) to change.
Interaction between Tone Adjust and MIDI CCs
A number of the Common Tone Adjust parameters can
affect parameters which are also modulated by dedicated
MIDI CCs. The speciﬁc CC numbers are noted in the
descriptions for the individual Tone Adjust parameters. For
more information, please see "Tone Adjust Parameters" on
Tone Adjust and the CCs work independently. It's possible,
for instance, for Tone Adjust to reduce the value of a
parameter, and then for a CC to increase it again.
Tone Adjust scales the parameter ﬁrst, and then the CC
scales the result of the Tone Adjust.
