ENVELOPE a single 4-stages amplitude EG.
LFO modulates only the amplitude with variable depth, delay time and 9 shapes: triangle, sinewave, square, saw up, saw down, trill (x2) and random (x2). Special AUTOBEND function is a basic modulation for a pitch-warp effect, so it should be considered as another simpler LFO.
EFFECTS there are 2 main FX sections with limited edit parameters:
- reverb: 9 presets including hall, delay, room and gate
- chorus: 5 presets including chorus, flanger and delay.
ARPEGGIATOR & CHORD PLAY a basic arpeggiator system with no sync Midi clock: up / down / updown / random. A chord can be assigned to each key, allowing you to play chords with a single finger. Since a different chord can be assigned to each key C, C# - B, you can perform using diatonic chords or harmonies in thirds. Up to 8 sets of chords can be stored in the U-20 (diatonic, Sus 4, octave, power)
MEMORY 64 patches + 64 performances + 4 rhythm sets. RAM is doubled if RAM card model Roland m-256 is fitted.
