DISPLAY PAGE TIME PANEL LABEL DELAY PARAMETER DISPLAY DELAY Delay Time OPTIONS or RANGE DESCRIPTION OFF ··· 131. 05 S From the moment a Note On occurs, this parameters sets the amount of time that elapses before the envelope begins its ATTACK stage. The amount of time it takes the envelope to rise from minimum to maximum amplitude, from 2 milliseconds to 131. 05 seconds. Note that Attack (and Release 2, next page) differs from the other envelope times in that a 2ms time minimum is required. The amount of time it takes the envelope to decrease from its maximum amplitude to the D2 LEVEL. The amount of time it takes the envelope to decrease from the D2 LEVEL to SUSTAIN level. The SUSTAIN level is the target level whether a note is being held or not. ATTACK ATTACK Attack Time 2 M ··· 131. 05 S fl DECAY 1 D1TIME Decay 1 Time OFF ··· 131. 05 S fl DECAY 2 D2TIME Decay 2 Time OFF ··· 131. 05 S DISPLAY PAGE PANEL LABEL PARAMETER DISPLAY OPTIONS or RANGE DESCRIPTION ANDROMEDA A6 REFERENCE MANUAL 137 Chapter 6: Modulation and Envelopes TIME TIME Parameters (continued) -- SHAPE Designed after the CURVE function of the PORTA EXP 1, 2 & 3 function, SHAPE refers to the slope (acceleration or deceleration attributes) of the envelope's LOG 1, 2 & 3 Attack, Decay 1, Decay 2, Release 1 and Release SCURV1 & 2 2 stages. This parameter is active at all times for all time parameters except DELAY. To select a particular slope for a time parameter, select the parameter by tabbing with soft button 1, then use soft knob 5 to select the desired slope. The display will show an envelope graphic that will depict the slope selected for each stage. See the SHAPE topic on the following page for a detailed description of the A6's stage slopes. LINEAR RELEASE 1 R1TIME Release 1 Time OFF ··· 131. 05 S The amount of time it takes the envelope to decrease from the SUSTAIN LEVEL to the RELEASE 2 LEVEL; this is the envelope stage entered when a Note Off occurs. RELEASE 2 R2TIME Release 2 Time The amount of time it takes the envelope to 131. 05 S decrease from the RELEASE 2 LEVEL to zero, from 2 milliseconds to 131. 05 seconds. Note that Release 2 (and also Attack, previous page) differs from the other envelope times in that a 2ms time minimum is required. 2 M ··· Important Note: If R2TIME is set to its maximum value, the envelope will enter into "infinite release". This means that when the envelope reaches this stage, it will hold at its R2LEVL (see page 141) indefinitely until you change to another Program or Mix, or turn the A6 off. To alert you that R2TIME has been set to its maximum, the HOLD LED on the front panel for that envelope will light. 138 ANDROMEDA A6 REFERENCE MANUAL Chapter 6: Modulation and Envelopes SHAPE: Selecting the Stage Slope Each time parameter of an envelope (except Delay) has a user-selectable property called slope. This term refers to how the attack, decay and release stages accelerate (speed up) or decelerate (slow down) as each stage approaches its target level. When a time stage parameter is selected, its current slope appears in the far right side of the display. Use Soft Knob 7 to make your selection: · A LINEAR slope means that the time settings do not accelerate (or decelerate) as the stage progresses towards its target level. In the illustration above, notice that the linear slope is depicted as a straight line (from where we get the term "linear"). The stage doesn't speed up or slow down in its duration but keeps an even rate of change. ANDROMEDA A6 REFERENCE MANUAL 139 Chapter 6: Modulation and Envelopes · An EXP (exponential) slope, however, accelerates towards the target level: it starts out slow then speeds up as it gets closer to its target level. Rather than a straight line, it is represented by a curve. One of three exponential curves can be selected: EXP 1 EXP 2 EXP 3 less steep than EXP 2 standard exponential curve steeper than EXP 2 · In contrast, the LOG (logarithmic) slope decelerates towards the target level: it starts out fast then slows down as it reaches its target level. It is represented by a curve that is the opposite of the exponent. One of three logarithmic curves can be selected: LOG 1 LOG 2 LOG 3 less steep than LOG 2 standard logarithmic curve, pictured above steeper than LOG 2 · The SCURV ("S"-Curve) combines the slopes of EXP 2 and LOG 2. One of two Scurves can be selected: SCURV1 The rising-amplitude of S-Curve 1 is characterized by acceleration during the first half of its stage using EXP 2, then decelerates during the last half using LOG 2. This is commonly known as a forward progression s-curve. [. . . ] It's better to use a damp plug to clean the jacks, or use a cotton or foam swab (but be careful not to get cotton or foam stuck in the unit). While Alesis does not endorse the use of any specific product, certain contact enhancers (such as CramolinTM) may be used to keep the connections from corroding in the future. · · · · · 272 ANDROMEDA A6 REFERENCE MANUAL Appendix D: Specifications SPECIFICATIONS MIDI IMPLEMENTATION CHART Function Basic Channel Mode Note Number Velocity After Touch Pitch Bender Control Change Prog Change System Exclusive System Common System Realtime Aux Messages Song Position Song Select Tune Request Clock Commands Local On/Off All Notes Off Active Sense System Reset 0 - 120 Default Changed Default Messages Altered True Voice Note On Note Off Keys Ch's Transmitted 1 - 16 1 - 16 each Mode 3 X Recognized 1 - 16 1 - 16 each Mode 3 X 33-96 33-96 O X X O O O O1 0 - 127 0 - 127 Remarks Memorized ******** 33-96 ******** O O X O X O O1 0 - 127 Transmitted from CV pedals True # ******** O X X X O O X X X X 1 O, X is selectable O X X O O O X O X O CC #122 CC #123 CC #121 Notes Mode 1: OMNI ON, POLY Mode 2: OMNI ON, MONO Mode 3: OMNI OFF, POLY Mode 4: OMNI OFF, MONO O : Yes X : No For a more information on the A6's MIDI SysEx implementation, see the Alesis website.
