TRIM/LOOP Function Knob 2 Length = unlock, lock This option lets you lock in the waveform's play length (the distance between the wave start and wave end addresses) and loop length (the distance between the loop-start and loop-end addresses). You enable this option by setting it to lock. If you do this, any change you make to any of these addresses will generate an equal change in the corresponding address - so that you can shift the playback or loop position along the waveform while maintaining constant playback length and loop length. You will want to use this feature, for example, when you need to keep the playback or loop length at some fixed value for timing purposes. Start Address End Address Waveform Play Length (This length is locked. Changing either address causes an equal change in the opposing address.) Knob 3 Loop Length (This length is also locked.) Loop Start Address Loop End Address Zero = off, on This "automatic zeroing" option is another convenient feature for address editing. If you enable this option, any address change you make will be forced to the nearest zeropoint - the address will jump from zero point to zero point as you turn the editing knob. If you disable this option, then you can change addresses continuously over the entire waveform. If Zero = off: If Zero = on: You can move the address to any location on the waveform Address always jumps to nearest zero-point on the waveform. Setting an address on a non-zero point may cause the sample to "click" during playback. Forcing the address to a zero-point will ensure that you avoid this unwanted click. 162 Chapter 5 EDIT Mode
