This feature increases the number of MIDI CC message types that are recognised by the TNR.
The stock TNR firmware responds to the following MIDI CC message types, consistent with the MIDI implementation chart in the service manual.
|0, 32||Bank Select MSB, LSB||Used to select the instrument|
|8||Balance||Layer balance/pan position|
|11||Expression||Layer expression (a percentage of the volume)|
|91||Effect 1 Depth||Amount of reverb|
|93||Effect 3 Depth||Amount of chorus|
Dissassembling the code running in the underlying SWL-01 tone generator reveals that actually the TG will respond to more CC message types than this; the chip is actually shared by a number of other Yamaha products that have a richer set of CC responses.
Since A034, the code has been modified to restore the original functioning of the following MIDI CC messages, although not all effects are audible with certain instruments.
|1||Modulation||The modulation wheel on keyboards|
|64||Damper Pedal||On/Off switch that controls the sustain pedal|
|66||Sostenuto Pedal||On/Off switch like Damper pedal, but only holds notes that are on when the pedal is pressed|
|67||Soft Pedal||On/Off switch that lowers the volume of played notes|
|71||Timbre||VCF filter shaping : Resonance/Timbre|
|72||Release Time||VCA filter shaping : Release time|
|73||Attack Time||VCA filter shaping : Attack time|
|74||Brightness||VCF filter shaping : Cutoff frequency|
|84||Portamento||Amount of portamento (appears to do nothing)|
|92||Effect 2 Depth||Amount of tremolo (odd effect)|
|120||All Sound Off||All Sound off|
|121||Reset Controllers||Resets all CC parameters to default|
|123||All Notes Off||Treated as “All Notes Off”|
|124||Omni Mode Off||Treated as “All Notes Off”|
|125||Omni Mode On||Treated as “All Notes Off”|
|126||Mono Mode||Treated as “All Sound Off”|
|127||Poly Mode||Treated as “All Sound Off”|
Several of these have also been made available as meta controllers.
Resetting controller values to their default can be achieved either by sending CC 121 “Reset Controllers”, or changing the instrument via [L1].
First included in A034.
