Build EP-40 multisamples, and edit single samples for any EP device
This is where multisamples come together. The EP-40 supports 5 different playback modes and up to 8 zones per multisample. The official tool doesn't let you create these at all.
Drag in your samples, map them across the keyboard, tweak the envelope and other parameters, then send it to your device. That's it.
Since v0.31, Kit mode is available in the editor with full feature parity: a hardware-style pad grid with drag-to-assign and LED indicators. Auto zone mapping and scale-aware distribute are included in the free tier.
Which devices?
The editor works with every EP device, but not every mode does. Multisamples (Multi and Kit modes) and Loop mode are EP-40 only, since only the EP-40 uses Teenage Engineering's TNGE multisample format. For the EP-133 and EP-1320, use the editor to trim, process and tune single samples, then send them across. The zones, envelope and 8-sample limit covered below are all EP-40 territory.
Choose from 5 different playback modes depending on your needs:
One-shot playback of a single sample. Perfect for drum hits, sound effects and samples that play once without looping.
Use for: Kicks, snares, percussion, FX
Continuous looping playback of a single sample. Ideal for sustained sounds and textures.
Use for: Pads, drones, atmospheric textures
EP-40 only: loops use the EP-40 format and won't carry over to the EP-133 or EP-1320.
Single sample mapped across the keyboard with pitch shifting. Create melodic instruments from a single recording.
Use for: Bass lines, lead melodies, simple instruments
Multiple samples (2-8) mapped to keyboard zones for melodic instruments. Each zone can have its own root note and key range.
Use for: Realistic instruments, chromatic synths, complex melodic patches
EP-40 only: multisamples use the EP-40 format.
Multiple samples (2-8) mapped to individual keys for drum kits. Each pad triggers a different sample. Kit mode includes a hardware-style pad grid with orange LED indicators for loaded pads and drag-to-assign functionality.
Use for: Drum kits, percussion sets, sound collections
EP-40 only: Kit mode builds a multisample, so it's EP-40 format.
Tip: Use Z/X keyboard shortcuts to navigate octaves in Kit mode
Adding audio files to your multisample:
Sample Limits
Maximum 8 samples per multisample, with a total duration limit of 20 seconds across all samples. The app will warn you if you exceed these limits.
The virtual keyboard shows how your samples are mapped across the EP-40's pads:
Tools for quickly mapping samples across the keyboard in Multi and Kit modes:
Automatically assigns root notes and zone boundaries for your samples. Available to all users (previously Pro-only).
Evenly distributes zone boundaries across the keyboard, respecting the selected musical scale. Supports all 10 EP device scales including Major, Minor, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian, Pentatonic and 12-tone Chromatic.
Type-ahead filtering in the note dropdown lets you quickly find and assign root notes. Press Enter to select the first matching result.
Set the play mode for each sample to control how it behaves on the device:
The play mode is saved with your sample and transferred to the device.
Control sound shaping for your entire multisample or individual zones:
The EP-40's envelope is attack and release only (there's no decay or sustain), and it's global to the whole multisample rather than per zone.
Click on any loaded sample to access advanced editing tools:
EP-PatchStudio can import drum kits from the Teenage Engineering OP-1:
Saving your multisample:
If you loaded a sample from your device, the "Upload to Slot" button lets you send it back to the original slot after editing, no need to browse for the right location.
You can also save a multisample as a WAV file to back up or share your work. The EP-40 uses the TNGE format, which is a WAV with the keyboard mapping baked in, so you can load it straight back into EP-PatchStudio later.
