Create a sampler bank

Turn your recordings into a keyboard instrument or drum kit for Maru Sampler. Use Studio to add the audio, ask an agent to arrange it, and adjust the mapping before exporting.

For a first kit, start with a kick, snare and a few hi-hats. For a melodic instrument, start with a few notes recorded at known pitches.

Add source material

Open Studio, create a new project and choose Sampler bank. In Sources, add your recordings or import an existing bank. Describe the result you want in chat. For example:

Make a drum kit from these recordings. Put the kick and snare on separate pads, let each hit play to the end, and make the closed hi-hat stop the open hi-hat.

You can also start from a catalog instrument that offers Edit bank in Studio. This creates your own editable copy. Read any import report before continuing; settings from another sampler or a custom interface may not carry over. Keep the original download if it has a custom interface. To continue an existing copy, reopen it in Studio rather than choosing Edit bank in Studio again, which creates another copy.

Only use material you have permission to upload and use. Generation, when available, provides another way to find candidates for the bank.

Map and listen

Use Mapping to assign recordings to notes, pads and velocity ranges. Adjust root notes, tuning and levels, then play the result in Preview. Try different notes and playing strengths to hear gaps or uneven changes. For a kit, check that each pad triggers the intended hit and that your hi-hat choke group behaves as expected.

A different layout can reuse the same source material. Presets keep sound choices; mappings decide how that material is played. See sampler concepts for the distinction.

Play and share your instrument

Open Info & export → Export bank and choose Download MAS or Download ZIP. The .mas option gives you one bank file containing the recordings, mappings, presets and artwork. ZIP contains the same bank content in an archive you can extract and inspect. Neither option requires you to compile a new plug-in.

To keep working on a downloaded bank, return to Sources and choose Import bank ZIP or MAS…. A saved Studio project remains your editing workspace; the downloaded bank is the file you take to a compatible player or pass to another musician.

For a DAW, the player is the native Maru Sampler plug-in, with your bank loaded inside it. The standalone app plays without a DAW. Public native downloads are upcoming; see the Sampler app and plug-in guide for availability.

To let someone play in their browser, publish a saved bank as a public or unlisted instrument page. Publishing and exports explains the sharing paths and their requirements.

For the detailed editor workflow and supported import/export behavior, see sampler banks.

Prepare the bank for other people

Provide a useful starting sound, explain the intended playing range or pad layout, and check that the delivered bank includes what its reader needs. Review content rights and visibility before making recordings public.

For a paid instrument or bank, follow selling on Maru. Adding generation later is a separate product choice, covered in generation inside instruments.
