Controlling GS Format Instruments
=================================
MIDI messages can be used to control numerous features of GS Format
instruments. The following article documents some of the most useful
and commonly used MIDI messages.
Effects for GS Format Instruments
=================================
The amount of Reverb and Chorus can be set for each MIDI channel in a
GS instrument by use of a MIDI Controller (CC). These examples are for
changing the effect amounts for Channel 1.
Effect 1. Reverb Send Depth
Ch CC Value
1 91 mm mm = 0---->127 (amount of Reverb)
Effect 3. Chorus Send Depth
Ch CC Value
1 93 mm mm = 0---->127 (amount of Chorus)
SOME USEFUL NON REGISTERED PARAMETER NUMBERS
============================================
Non Registered Parameter Numbers (NRPN) allow control of a number of
sound paramenters within GS Format instruments by the use of MIDI
Controllers(CC). The NRPN's are Channel Messages. In the following examples,
we assume that we are programming parameters for sounds on MIDI Channel 1.
Vibrato Rate.
Ch CC Value
1 99 1
1 98 8
1 6 mm mm = 14---->64---->114.
This means that 64 is the default setting, 14 will produce
minimum vibrato rate whereas 114 will produce maximum vibrato rate.
Vibrato Depth.
Ch CC Value
1 99 1
1 98 9
1 6 mm mm = 14---->64---->114
Same explanation as for vibrato rate.
Vibrato Delay.
(Controls delay from start of tone to full amplitude vibrato).
Ch CC Value
1 99 1
1 98 10 mm = 14---->64---->114
1 6 mm
Same explanation as for vibrato rate.
TVF Cutoff Frequency.
(Controls the cutoff frequency at which the programmable Low Pass filter
associated with each tone starts attenuating).
Ch CC Value
1 99 1
1 98 32
1 6 mm mm = 14---->64---->114
Same explanation as for vibrato rate.
TVF Resonance.
(Controls the amplitude of the peak at the cutoff frequency of the filter)
Ch CC Value
1 99 1
1 98 33
1 6 mm mm = 14---->64---->114
TVF & TVA Envelope Attack Time.
(Controls the time for the Time Variable Filter and the Time Variable
Amplifier to reach respectively their programmed frequency and amplitude after
keying the tone).
Ch CC Value
1 99 1
1 98 99
1 6 mm mm = 14---->64---->114
TVF & TVA Envelope Decay Time.
(Controls the duration of the decay of the TVF and TVA envelopes).
Ch CC Value
1 99 1
1 98 100
1 6 mm mm = 14---->64----->114
TVF & TVA Envelope Release Time.
(Controls the duration of the release time of the TVF and TVA envelopes after
a key is released).
Ch CC Value
1 99 1
1 98 102
1 6 mm mm = 14---->64---->114
Pitch Coarse of Drum Tone.
(Changes the pitch of a drum tone corresponding to a key in semitone
increments or decrements)
"rr" represents the key number from the Drum Set table.
Example: Side Stick = 37. (10 = MIDI Ch. 10)
Ch CC Value
10 99 24
10 98 rr
10 6 mm mm = 00---->64---->127
(64 is the default setting.)
Example: If we wish lower the pitch of the Side Stick by 4 semitones we would
write:
Ch CC Value
10 99 24
10 98 37
10 6 60
Panpot of Drum Tone.
(Controls the perceived direction from which the sound originates between the
two speakers).
Ch CC Value
10 99 28
10 98 rr rr = Drum Key Number
10 6 mm mm = 1---->64---->127
Left Center Right.
Random Panning of Drum Tone.
(Perceived direction from which Drum sound originates changes randomly with
each keydown).
Ch CC Value
10 99 28
10 98 rr rr = Drum Key Number
10 6 0
Reverb Send Depth of Drum Tone.
Ch CC Value
10 99 29
10 98 rr rr = Drum Key Number
10 6 mm mm = 0---->127
Chorus Send Depth of Drum Tone.
Ch CC Value
10 99 30
10 98 rr rr = Drum Key Number
10 6 mm mm = 0---->127
Common System Exclusive Messages for ALL Sound Canvas
and GS Format Instruments
===========================================================
The following messages are commonly used and useful messages for
sequenceing with the Sound Canvas family of instruments.
The GS Reset:
============
Resets all Part parameters to factory default, including MIDI Channel,
Level, Pan, Reverb, Chorus, Key Shift and more.

Assigning a 2nd MIDI Channel to Play Drums
==========================================
By default the drums are assigned to MIDI Channel 10. Sometimes it is
desirable to have simultaneous access to two drum sets. If we wish to
assign channel 11 to play drums, the complete message will be:
F0 41 10 42 12 40 1A 15 02 0F F7
Different Program changes for the drums in Channel 10 and 11 will
allow us to play two different drum sets at the same time.

NOTES:
This info is offered on an AS IS basis. Improper use of SysEx commands may
result in a synth being reset or patches deleted! Please contact the
manufacturer of the device in question to obtain the proper SysEx messages.
We cannot assume any responsibility for lost data.
SySex data implementation is not supported by our support staff. The USB and
the Standard 15 pin Joystick MIDI Cable - as well as our Software programs -
are capable of delivering SySex Data or any MIDI information, however, when
it comes to importing or exporting SySex, things get easily complicated as
they there are too many parameters that can go wrong.
Customers are responsible on their own for configuring advanced concepts
such as SySex or PatchMaps.
