About the COMMANDS Knob 4 [ Turn] length Turn the knob to set the length for the fade, in "address" units. The minimum length is 0 (no fade). The maximum length is equal to the entire playback length of the waveform (the length from the start address to the end address). Note again that fade-in always begins from the start address, while fade-out always ends at the end address. [Range] 0 - Wave length Knob 5 [ Turn] length % Specifies the length of the fade in or fade out as a percentage of the wave length. This parameter works in conjunction with the length (Knob 4) parameter. [Range] 0% - 100% [ Press] EXEC&CONT Press this knob to call the fade confirmation display. Press Knob 5 (YES) to actually execute the fade operation. Processing if Crossfade Area = sustain: Start Address Loop Start Address Loop End Address End Address A BC DE F Width (where C - D = 100%) Step 1: Copy waveform piece from end of segment A - B into a buffer. Extract piece of equal length from the end of C - D, and copy into another buffer. The length of these pieces is determined by the Width setting. Step 2: Apply fade-in processing to the A - B piece, and fade-out processing to the C - D piece. Step 3: Combine the two resulting waveforms, and write the result into the extraction area at the end of C - D. Processing if Crossfade Area = release: Start Address Loop Start Address Loop End Address End Address A BC DE F Width (where C - D = 100%) Step 1: Copy waveform piece from start of segment C - D into a buffer. Extract equal piece from the start of E - F, and copy into another buffer. The lengths of these pieces is determined by the Width setting. Step 2: Apply fade-in processing to the C - D piece, and fade-out processing to the E - F piece. Step 3: Combine the two resulting waveforms, and write the result into the extraction area at the start of E - F.

Knob 2 [ Turn] Crossfade Area Selects the area over which crossfade is applied, and determines the segments that are used to generate the crossfade. [Range] sustain, release • sustain ... Generates the crossfade by merging the end part of the loop with the area just preceding the loop start. This method produces smoother sustained looping, and the crossfade recurs with each iteration. • release ... Generates the crossfade by merging the initial part of the loop with the initial segment following the loop area. This method produces a smoother loop release, and the crossfade occurs only once (as the loop is exited). This method is useful only with the "→O→" loop type. Knob 3 [ Turn] Curve This setting selects the curve type for the loop cross fade. Three types are available, as illustrated below. [Range] -exponent, linear, +exponent Fade-In Curves -exponent Level linear Level +exponent Level Fade-Out Curves -exponent Level Time linear Level Time Time +exponent Level Time Time Time Knob 5 [ Turn] Width Sets the length of the crossfade area, as a percentage of the total loop length. [Range] 0% - 90% [ Press] EXEC&CONT Press this knob to call the loop cross fade confirmation display. Press Knob 5 (YES) to actually execute the loop cross fade operation. 220 Chapter 9 COMMAND • A5000/A4000 q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q q
