21RE4: Amplitude Decay TrackDisplayed as: AmpDecTkInitial value: 0Range of adjustment: -64 to +63This parameter works in exactly the same way as Attack Track, except that it is the Decaytime of a note that becomes dependent on its position on the keyboard.RE5: Amplitude Sustain RateDisplayed as: AmpSusRtInitial value: FlatRange of adjustment: -64 to Flat to +63With this parameter set to Flat, the volume during the Sustain phase of the envelope re-mains constant. Additional variations to a note’s character can be obtained by causing thenote to become louder or quieter while the key is held. A positive value of Sustain Ratewill cause the volume to increase during the Sustain phase, and it will continue to do sountil maximum level is reached. The parameter controls the rate at which the note increasesvolume, and the higher the value, the faster the rate of increase. Any Release time set willact as normal when the key is released, whether or not the maximum volume has beenreached. If a negative value is set, the volume during the Sustain phase drops, and if thekey is not released, the note will eventually become inaudible.Lower values (positive or negative) of Amplitude Sustain Rate are generallymore useful.RE6: Amplitude Sustain TimeDisplayed as: AmpSusTmInitial value: 127Range of adjustment: 0 to 126, KeyOffThis parameter sets the duration of the Sustain phase. With a value of KeyOff, the note willremain audible continuously until the key is released (unless a negative value of SustainRate has been applied to reduce its volume). Any other value of Sustain Time will cutthe note off automatically after a pre-determined time if the key is still held down. ReleaseTime still applies if the key is released sooner. A value of 126 sets the Sustain time to ap-prox. 10 seconds, while values around 60 set it to about 1 second.RE7: Amplitude Level TrackDisplayed as: AmpLvlTkInitial value: 0Range of adjustment: -64 to +63This parameter works in a similar way to the other “tracking” parameters Attack Track andDecay Track (RE3 & RE4), but it is the volume of the note which is changed, according tothe interval between it and the Track Note set by RE8. With a positive value, notes higherthan the Track Note get progressively louder the further from the Track Note they are, andvice-versa. With a negative value, notes higher than the Track Note get progressively qui-eter the further from the Track Note they are, and again, vice-versa. Note that this volumemodiication is applied to all phases of the amplitude envelope equally; it is the overallvolume of the note which changes with Level Track. The effect should be used sparingly;low values have a better effect.Note that although Amplitude Level Track appears to operate in a very similarmanner to Amplitude Attack Track and Amplitude Decay Track, only Level Trackuses a user-deinable note as the reference (set by RE8), above which notesget louder and below which get softer. The Attack and Decay Track parameters (RE3 andRE4) have a ixed reference note at C 3.Common Envelope ParameterThis parameter is available on Page 2 of the menu for every Envelope.RE8: Level Track Reference NoteDisplayed as: LvlTkNteInitial value: C 3Range of adjustment: C -2 to G 8This sets the reference note used for Amplitude Level Track. When active, this parameterincreases the volume for notes above the chosen Track Note, and reduces it for notesbelow it. C 3, the default value, is Middle C on the keyboard; this is the C one octave abovethe lowest note on the keyboard (also C), providing no OCTAVE buttons [32] are selected.Envelope 2 (Filter) parameters (Page 1)The parameters available for adjustment with Envelope generator 2 closely match those forEnvelope generator 1. Whereas Envelope 1 is concerned with modiications to the sound’samplitude envelope, Envelope 2 gives you “dynamic” iltering, by establishing a relationshipbetween the ilter section and ADSR Filter Envelope 2, resulting in the ilter frequency be-ing varied by the shape of the envelope.In order to hear the effect of any of the Filter Envelope parameters, you will irstneed to go to the Filter Menus and set up some iltering. Then set RE5 on FilterMenu Page 1 (F1Env2 or F2Env2) to an initial value of approx. +30 and ensurethat the ilter is not fully open – i.e., set F1Freq to mid-range.RE1: Filter Attack TimeDisplayed as: FltAttInitial value: 2Range of adjustment: 0 to 127This parameter sets how the ilter section acts during the note’s Attack phase. The higherthe value, the longer it takes for the ilter to react during this phase.To evaluate the action of the Filter Envelope parameters for each of the ADSRphases (RE1 to RE4), it may be helpful not to set all three to zero.RE2: Filter Decay TimeDisplayed as: FltDecInitial value: 75Range of adjustment: 0 to 127This parameter sets how the ilter section acts during the note’s Decay phase. Again, thehigher the parameter value, the longer the period for which iltering is applied .RE3: Filter Sustain LevelDisplayed as: FltSusInitial value: 35Range of adjustment: 0 to 127The frequency of the ilter (cut-off or centre, depending on ilter type) “settles” at a valueset by the Filter Sustain Level. Thus, once the Attack and Decay stages of the envelopeare completed, the harmonic content that will be most evident in the sound will be deter-mined by this parameter. Remember that if the ilter frequency parameter (as set in the FilterMenu) is set at a too low or too high a value, the envelope’s effect will be limited.RE4: Filter Release TimeDisplayed as: FltRelInitial value: 45Range of adjustment: 0 to 127As Filter Release is increased in value, the note undergoes increasingly more ilter actiononce the key is released.Note that the Amplitude Release time (in Envelope 1’s parameters) must be setsuficiently high to produce an audible “fade-out” before the effect of iltering onthe “tail” of the note is evident.ATTACK DECAY RELEASESUSTAINSUSTAINRATETIMEKEY "ON" KEY "OFF"VOLUMEATTACK DECAY RELEASESUSTAINSUSTAIN TIMETIMEKEY "ON" KEY "OFF"VOLUME0 0 0 Sawtooth 0 127 0 0O1PtchWh O1WTInt FixNote ModVib MVibRate OscDrift OscPhase NoiseTyp+12 127 Off 0 65 0 0deg WhiteO2Semi O2Cents O2VSync O2Wave O2PW/Idx O2Hard O2Dense O2DnsDtn0 0 0 Sawtooth 0 127 0 0O2PtchWh O2WTInt FixNote ModVib MVibRate OscDrift OscPhase NoiseTyp+12 127 Off 0 65 0 0deg WhiteO3Semi O3Cents O3VSync O3Wave O3PW/Idx O3Hard O3Dense O3DnsDtn0 0 0 Sawtooth 0 127 0 0O3PtchWh O3WTInt FixNote ModVib MVibRate OscDrift OscPhase NoiseTyp+12 127 Off 0 65 0 0deg WhiteFILTERS F1Freq F1Res F1Env2 F1Track F1Type F1DAmnt F1DType F1QNorm127 0 0 127 LP24 0 Diode 64FBalance FRouting FreqLink ResLink-64 Parallel Off OffF2Freq F2Res F2Env2 F2Track F2Type F2DAmnt F2DType F2QNorm127 0 0 127 LP24 0 Diode 64FBalance FRouting FreqLink ResLink-64 Parallel Off OffENVELOPES AmpAtt AmpDec AmpSus AmpRel AmpVeloc AmpRept AmpTTrig AmpMTrig2 90 127 40 0 0 OFF Re-TrigAmpAtSlp AmpDcSlp AmpAttTk AmpDecTk AmpSusRt AmpSusTm AmpLvlTk LvlTkNte0 127 0 0 0 127 0 C 3FltAtt FltDec FltSus FltRel FltVeloc FltRept FltTTrig FltMTrig2 75 35 45 0 0 OFF Re-TrigFltAtSlp FltDcSlp FltAttTk FltDecTk FltSusRt FltSusTm FltLvlTk LvlTkNte0 127 0 0 0 127 0 C 3E3-E6 E3Att E3Dec E3Sus E3Rel E3Delay E3Repeat E3TTrig E3MTrig10 70 64 40 0 0 OFF Re-TrigE3AtSlp E3DcSlp E3AttTk E3DecTk E3SusRat E3SusTim E3LvlTk LvlTkNte0 127 0 0 0 127 0 C 3
