Getting started with the EP-40 Riddim
The EP-40 Riddim packs sampling, four instrument groups, and a built-in Supertone synth into one pocket-sized box. This guide walks you from a fresh project to a finished beat, loading sounds, recording patterns, and saving your work as a scene.
Start a new project and load sounds
Power on, then open a clean workspace before you start building.
- Hold MAIN and tap a pad 1-9 to pick a project (projects 6-9 are empty on new units).
- Press SOUND, select Group A and a pad, then use minus/plus to scroll through sounds.
- Browse by category: kicks 1-99, snares 100-199, hi-hats 200-299, percussion 300-399, bass 400-499, melodic 500-599.
Organize as you go: use Group A for drums, B for bass, C for melodies, and D for loops and samples.
Hold SOUND, press the dot button, then use minus/plus to browse 10 built-in Supertone synth presets on pads 0-9.
Record your first pattern
Enter main mode and lay down a beat with the pads.
- 1
Press MAIN to enter main mode.
- 2
Tap RECORD, then PLAY for a count-in.
- 3
Hit the pads to play your sounds as the pattern loops.
- 4
Press PLAY to stop, or press RECORD to keep playing without recording.
- 5
Set pattern length by holding RECORD and pressing PLUS (default is 1 bar).
For a quick take with no count-in, press RECORD and PLAY together.
Build it out with more groups
One group is a start, but a full beat layers all four.
- Switch to Group B for a bassline, then Group C for a melody.
- Press KEYS to turn the selected pad into a chromatic keyboard for playing notes.
- Each group keeps its own pattern, but all four play together in a scene.
Sample sounds and add effects
Make the track your own by recording your own audio and shaping the mix.
- Press SAMPLE and hold a pad to record from the mic or line in.
- Press FX, move the fader up, and use minus/plus to switch between effects.
- Hold FX and tap pads for momentary punch-in effects.
Save your work as a scene
Commit captures all four groups together as a snapshot you can return to.
- Press SHIFT and MAIN to commit.
- This saves your current pattern arrangement as a scene and starts a new one.
Save a scene before making big changes so you never lose an arrangement you like.
A project holds up to 99 scenes, so commit often as you build different sections of your track.
questions
How do I start a fresh project on the EP-40 Riddim?
Hold MAIN and tap a pad 1-9 to select a project. On new units, projects 6-9 are empty, so pick one of those for a clean start.
How are sounds organized by number?
Sounds are grouped by type: kicks are 1-99, snares 100-199, hi-hats 200-299, percussion 300-399, bass 400-499, and melodic sounds 500-599. Use minus/plus in sound mode to scroll through them.
How do I record without a count-in?
Press RECORD and PLAY at the same time to drop straight into recording. The standard way, tapping RECORD then PLAY, gives you a count-in first.
What is the difference between a pattern and a scene?
A pattern is what a single group plays. A scene is a snapshot of all four groups together. Commit with SHIFT plus MAIN to save the current arrangement as a scene.
How do I play melodies instead of one-shots?
Select a pad and press KEYS to turn it into a chromatic keyboard. The pads then play notes from the pad's root pitch, which works with both samples and Supertone sounds.
Where do the built-in synth sounds live?
Hold SOUND, press the dot button, then use minus/plus to browse the 10 Supertone presets on pads 0-9. They are synthesized in real time and use no sample memory.
