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 parameters 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 Cut-off Frequency.

(Controls the cut-off frequency).

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 cut-off 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  Centre  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

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.
