*3When MSB is other than 0 or 127, this is 0.
When MSB = 0, this is 0,1,3,5,8,12,14,16,17,18,19,20,24,25,27,28,32,33,34,35,36,37,38,39,40,

When MSB = 127, this is 0.
MODULATION controls the depth of vibrato.
PORTAMENTO TIME adjusts the speed of the pitch change if the Portamento Switch = ON. A setting of
0 produces the shortest portamento time, and 127 produces the longest portamento time.
For consistency with the GMx Portamento Control
Standard, this value is valid only for the Portamento Switch (Ctr#65).
PANPOT produces change relative to the preset value of the voice, both for melody voices and for rhythm
voices.
For PORTAMENTO CONTROL, the portamento time is always fixed at 0.
EFFECT SEND LEVEL 1 controls the Reverb send.
EFFECT SEND LEVEL 3 controls the Chorus send.
EFFECT SEND LEVEL 4 controls the Variation send.
HARMONIC CONTENT adjusts the resonance specified by the Voice. This is a relative parameter, and
specifies an increase or decrease centered at 64. Higher values will produce a more distinctive tone. For
some voices, the effective range maybe less than the range of the setting.
RELEASE TIME adjusts the envelope release time specified by the Voice. This is a relative parameter, and
specifies an increase or decrease centered at 64.
ATTACK TIME adjusts the envelope attack time specified by the Voice. This is a relative parameter, and
specifies an increase or decrease centered at 64.
BRIGHTNESS adjusts the cutoff frequency specified by the Voice. This is a relative parameter, and
specifies an increase or decrease centered at 64. Decreasing the value will make the sound more mellow.
For some voices, the effective range may be less than the range of the setting.
The following Bank Select related operations will all occur when a Program Change is received.
Bank Select MSB:60h-6Fh are not sounded on models which do not support GMx, but since on the QY70
these are for future expansion of melodic voices, they will be sounded for the present by MSB00h.
If Bank Select MSB is other than 0,40H, 60H-6FH, 7EH, or 7FH, voice Off will be selected.
If Bank Select MSB = 0,40H, 60H-60FH, 7EH or 7FH is selected, unsupported BANK SELECT LSB
numbers will be ignored.
