point, then go back and forth between the Loop Start point and the Loop End point.

REV-ONE (Reverse One-shot)

The sample will be played back only once from the Loop End point to the Start point in the reverse direction.

REV (Reverse):

When the sample has been played back from the Loop End point to the Start point, it will be repeatedly played back in the reverse direction, from the Loop Start point to the Start point.

Tune (Loop Tuning)

Range: -50–50

Determines the fine pitch setting within the loop, in one-cent steps (1/100 of a semitone).

Start-Fine (Start Point - Start Point Fine)

•Start Point Range: 0–

Specifies the point in the sample from which data will be read.

•Start Point Fine Range: 0–255

This is a fine adjustment of the Start Point.

Loop Point Start-Fine (Loop Start Point - Loop Start Point Fine)

•Loop Start Point Range: 0–

Specifies the point in the sample from which the loop will be started.

•Loop Start Point Fine Range: 0–255

This is a fine adjustment of the Loop Start Point.

End-Fine (End Point - End Point Fine)

•End Point Range: 0–

Specifies the point to which the loop will be read.

•End Point Fine Range: 0–255

This is a fine adjustment of the End Point.

Using the Filter to Modify the Brightness ([F3 (TVF)])

The settings for the TVF (Time Variant Filter) allow you to change a Tone’s timbral content by altering its brightness or thickness.

TVF

Filter Type (TVF Filter Type)

Selects the filter type. A filter typically reduces, or attenuates, a specific frequency range within a Tone in order to accentuate its other frequencies.

Available Settings:

OFF: No filter is used.

LPF: Low Pass Filter. This reduces the volume of all frequencies above the cutoff frequency. Since the high frequency range is cut, the sound will become more mellow. This is the most frequently-used type of filter.

BPF: Band Pass Filter. This type of filter leaves only the region in the vicinity of the cutoff frequency, and cuts the rest. It is useful for making distinctive sounds.

HPF: High Pass Filter. This type of filter cuts the portion that lies below the cutoff frequency. It is useful for making percussive or other sounds. that have a distinctive high range.

PKG: Peaking Filter. This emphasizes frequencies around the cutoff frequency by raising their level. You can use this to create wah-wah effects by employing an LFO to change the cutoff frequency cyclically.

LPF2: Low Pass Filter 2. This reduces the volume of all frequencies above the cutoff frequency. This differs from LPF in that you can control the amount of the reduction using the TVF ENVELOPE settings while still maintaining a fixed cutoff frequency.

This can be very effective with acoustic-instrument-based Tones, since nothing is done to weaken the power and energy of the sound.

* This disables the Resonance setting.

LPF3: Low Pass Filter 3. This type of filter cuts the portion that lies above the cutoff frequency. While similar to LPF2, it
