The Loop Modes Explained

To truly understand the A3000 it is necessary to get the difference between the Wave Start / Wave End Address Points and the Loop Start / Loop End Address Points. Basically, Wave here refers to the audible portion of the recorded data. In other words, the Wave Start Point is where in the recorded data you have determined the first useful sound data begins. The Wave endpoint is the last bit of useful data. Meanwhile, the Loop Start and Loop End Points are pointers that tell the A3000 to play the data located in between again and again until either note off or until the envelope ends the sound. Notice that the Loop Start and End points must always lie inside the Wave Start and End points.

The “LpMode” or Loop Mode parameters are as follows:

1.→ means the sample will play forward once from Wave Start to Wave End Points, following the envelope settings. Typically, it behaves like a keyboard note-on. Lift your finger and the sound stops.

2.ShotÆ Is different from the above in that it will complete playback in spite of note-off. Typcially this is used as a drum trigger.

3.← means the sample will play in reverse once from Wave End to Wave Start Points following the envelope settings, like a keyboard sound.

4.←Shot plays in reverse like a drum pad triggered sound. It ignores the note-off.

5.→0 means the sample plays forward, and will loop the sections defined by the Loop Start to Loop End addresses. It will follow the envelope release settings and fade out on that loop section.

6.→0→ will play the sample forward from the Wave Start Point, and will loop the sections defined by the Loop Start and Loop End address. It will remain in the loop section until note off, when it will continue on to the Wave End Point. For example, you record yourself counting “1 – 2 – 3 – 4 – 5”. Your Wave Start point would be just prior to the word “one”. Your wave End point would be just after the word “five”. If you set Loop Start just prior to the word “two” and Loop End just after the word “three”. When you press a note-on you would get: “one, two, three, two, three, two, three, two, three…(etc)” until note-off when you would hear the final “two, three” complete playback followed by “four, five.” (Assuming the release envelope allows the decay.)

Missing from this list is 0←, which would represent a reverse loop. Does this mean the A3000 does not do reverse looping? No, but it is handled a little differently. To create a reverse loop you will have to create a reverse version of the recorded data. This is accomplished by pressing the [COMMAND] button from any TRIM/LOOP screen and using Knob #1 to navigate to the [REVERS] screen. You execute reversing the current wave by pressing Knob #1, and confirming with Knob #5.

Effect Processors

Within the A3000 are three effect processors each with 54 algorithms. These are not your run of the mill 24-bit effect processors either. There are plenty of brand new algorithms developed specifically for this product. Some of the more uniquie ones are: Scratch (a programmable digital scratch), Auto Synth; Techno Modulation; Noisy delay; Flanger Pan; Radio; LoFi; TurnTable (programmable record surface noise), Beat Change (modifies
