- ...fx/ : Effects project files.
- Crusher - Bit crusher and decimator effect.
- Gator - Kaossilator-style gate arpeggiator.
- Hyper - unison effect inspired by supersaw/hypersaw.
- Kompressor - RMS downward compressor/expander.
- Looper - Kaossilator-style loop recorder.

- Most of the effects 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 loop length automatically reduced depending on the record 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 | - | - |
