1. OSCILLATOR

This produces the basic waveform.

• Portamento

This smoothly connects changes in pitch.

• OSC Balance (oscillator balance)

Adjust the level balance of the two oscilla- tors.

• OSC2 Pitch Offset (oscillator 2 pitch offset) Adjust the pitch difference between OSC1 and OSC2.

• OSC1 Wave (oscillator 1 wave) Select the waveform for OSC1.

• OSC2 Wave (oscillator 2 wave) Select the waveform for OSC2.

•OSC Mod (oscillator modulation)

Specify the type of oscillator modulation. The modulated sound will be output from the OSC2 side.

2. Original Value LED

This will light when the knob you are currently moving reaches the value of the original saved sound of the pattern.

3.Motion Seq (motion sequence)

This function allows you to loop knob movements. Each time you press this key, the setting will alternate between Off (dark), Smooth, and Trig Hold.

4. Part Select key

Each time you press this key, Part 1 and Part 2 will alternate as the part selected for editing.

6. FILTER

These controls let you adjust the brightness of the sound or add a distinctive tonal char- acter.

•Cutoff: Adjust the cutoff frequency of the filter.

•Resonance: Adjust the resonance of the filter.

•EG Int (EG intensity): Adjust the depth of the filter envelope.

•Decay: Adjust the decay speed of the filter envelope.

7. AMP

Here you can adjust the volume level and the distortion effect.

•Distortion: Switch distortion on/off.

•Level: Adjust the volume level.

8. EFFECT

Here you can add effects to the sound.

•Depth: Adjust the depth of the effect (tempo delay, chorus/flanger).

•Time: Adjust the delay time, or the speed of the chorus/flanger LFO.

•Type Select: Choose the effect (tempo delay or chorus/flanger) that will be adjusted by the Depth and Time controls.
