- source 1 modulates source 2
- source 3 modulates source 4
Wavetable
16 bits ROM contains 256 waves split into 2 categories:
-
96 PCM DC digital cyclic: mathematically precalculated fundamental and basic waveforms
- 160 PCM acoustic samples categorized into 4 subgroups: drums, multi, block and reverse & loop
Performance
system manages up to 8 parts all variable settings:
Envelope

LFO
1 main delayed modulator (shapes: triangle, saw, square and random) and 3 destinations: pitch, filter 1 and filter 2. Second basic LFO for vibrato.
Memory
-
64 RAM slots for patches
-
64 RAM performances
Review
OK: wavetable / filter / affordable / great pads
NOT : edit / obsolete acoustic sound
"Compact version of classic K4 minus effects: lot of good sweep pads and powerful filters. "
