Part numbers are initially setto incoming MIDI channels.2 Use the cursor keys to navigate to the field youwant to change, and the wheel to change thevalues.There are three screens in all. Use the left and rightkeys to change between the screens (they don’t“wrap round”).The parameters you can edit are:• MUTE: Muting ON or OFF (muting ON means theinstrument is off).• INSTRUMENT: Select the instrument for this part fromthe standard GM instrument list.• Ch: The MIDI channel which will be used to playthis part.• KEY: Sets transposition (from +63 to -64 semitones).• PAN: Hard left is L63, center is C, hard right is R63.• VOLUME: 0 is no output level, 127 is full volume.The on-screen fader moves as you change thisvalue (there is no physical control corresponding tothis fader).• REVERB: The send level of this part to the tone gen-erator’s internal reverb effect.• CHORUS: The send level of this part to the tone gen-erator’s internal chorus effect.NOTEThe reverb and chorus of the tone generator are notconnected with the other effects as described in“Effects” on page 31, and all settings etc. are indepen-dent of these “main” effects. It is not possible to usethese tone generator effects with any sound sourcesother than the tone generator instruments.In addition to the instrument settings, the last screenof the GM EDIT series also allows you to pick the effectto be assigned to the tone generator reverb and cho-rus effects. Apart from the type of effect, no parame-ters are available for editing the effect sounds:NOTEIf you are playing back an SMF which includes anychanges to these parameters, or if an external ControlChange message is received to change any of them, thesettings you make here are overridden.Screen 1 Screen 2 Screen 3Reverb ChorusROOM1Room type reverbsCHORUS1Different “flavors” ofchorusROOM2 CHORUS2ROOM3 CHORUS3HALL1 Hall-type reverbs CHORUS4HALL2 FEEDBACK Feedback effectPLATE Plate-type reverb FLANGER Flanger effectDELAY Delay setting SHRT DLY Short delayPAN DLY Panned stereo delay FB DLY Delay with feedback
