Effects description
- Crusher - bit crusher and decimator effect.
- Gator - Kaossilator-style gate arpeggiator.
- Hyper - unison effect inspired by supersaw/hypersaw.
- Kompressor - Peak downward compressor/expander.
- Looper - Kaossilator-style loop recorder.
- Vibrator - frequency vibrato and pitch shift effect.
- LFO - frequency and amplitude vibrato with selectable waveform.
- Delay BPM - simple delay linked to BPM.

Notes
- Most of the effects are for all three effect slots.
- The third effect parameter control is not available for Modulation FX, thus several effects are limited in control in this slot.
- Due to NTS-1 SDRAM size limitation, the loop length is automatically reduced depending upon the recording format, and current BPM according to the table below:
| Record format |
BPM < 75 |
75 ≤ BPM < 150 |
| Stereo |
4 beats max |
8 beats max |
| Stereo packed |
8 beats max |
- |
| Mono |
8 beats max |

| Mono packed |
