SampleStack building a multisample instrument with keyboard zones and amp envelope

See it in action

From a messy folder of samples to a validated device card or a playable instrument, without leaving the app.

Every sample, in its place

Library management

Every sample, in its place

Browse your whole library in one window, Splice downloads and old drum kits alike. Tags, ratings, categories, notes, and key, automatic BPM detection for loops, color-coded validation, and search with filters by category, tag, and rating.

One library. Every destination.

Multi-output support

One library. Every destination.

Copy and convert from a single master library to hardware samplers, Eurorack modules, and software targets. Each destination gets the exact sample rate, bit depth, folder layout, and filenames it expects.

Turn one-shots into instruments

Multisample support

Turn one-shots into instruments

Drop in samples and SampleStack detects their pitch and maps them across the keyboard, or import an existing SFZ or Decent Sampler instrument to work from. Stack velocity layers, tune zones, shape the amp envelope, and play it back over MIDI or your computer keys.

Export to anything

Multisample export

Export to anything

Send your instrument out as SFZ, SoundFont 2, Decent Sampler (with artwork and controls), Ableton Sampler, disting EX and NT, or 1010music Bitbox. A built-in matrix shows what each format carries, and you can thin zones by pitch, round-robins, or velocity layers to fit a hardware target's limits.

Editing & native macOS

Edit right where you browse

Zoom into a stereo waveform to fade, crop, cut, and split, all non-destructive. Add splice markers or auto-detect transients, then save when you're happy. Built in SwiftUI and right at home in Light or Dark mode. Drag the slider to compare.

How it works

SampleStack knows what every supported device and software target wants, and does the tedious format work for you.

Multi-target support

Auto-detects your library structure for the Morphagene, Squid Salmple, Digitakt, Octatrack, Blackbox, and 30-plus other devices, plus software targets like SFZ and Decent Sampler. Each has its own rules. SampleStack knows them.

Instant validation

See at a glance which samples are ready, which need conversion, and which have issues. Color-coded badges show you what needs attention.

Built-in audio editing

Preview with a zoomable waveform. Add cue points and splice markers, detect transients, apply linear or logarithmic fades, split, crop, and extract, all non-destructively. Loop crossfades use equal-gain curves. Save when you're ready, or discard and start over.

Why SampleStack

Hardware samplers have strict rules. Wrong sample rate, wrong bit depth, wrong filename, and your samples won't load. SampleStack takes the guesswork out by validating and converting against the target automatically.

Target-aware validation

Every sampler has its own rules. Morphagene wants 32-bit float stereo. Squid Salmple wants 16-bit mono at 44.1 kHz. SampleStack detects the target from your folder, then validates sample rate, bit depth, channels, duration, and filenames against its spec.

Non-destructive editing

Preview edits before committing. Cue points, linear and logarithmic fades, crop, cut, split, and extract, plus transient-based slicing and equal-gain loop crossfades. Everything stages until you save. Discard anytime to revert to the original.

Fits your workflow

Keep your master library however you like it. Drag samples from the companion window into Ableton Live, Logic Pro, FL Studio, or any other DAW, or into device collections when you need them on hardware. SampleStack handles the conversion in the background.

54 supported instruments

Frequently asked questions

What people ask most often about SampleStack and managing samples for hardware.

What is SampleStack?

SampleStack is a native macOS sample library manager and multisample instrument builder. It organizes your library, then validates, converts, and exports audio to match what hardware samplers, Eurorack modules, and software targets want, from a Make Noise Morphagene reel to a Decent Sampler instrument.

What is a sample manager and why do I need one?

Every hardware sampler has its own requirements: sample rate, bit depth, channel count, folder structure, naming conventions. Get any of them wrong and your samples won't load. A sample manager handles those rules for you so you can spend your time on the music instead of file plumbing.

Which modules and samplers does SampleStack support?

SampleStack supports 30-plus hardware devices, including the Morphagene, Squid Salmple, Multigrain, disting EX and NT, Nebulae v2, ER-301, Sample Drum, Radio Music, Rample, Assimil8or, Blackbox, Bitbox, Digitakt II, Octatrack MKII, Tracker Mini, Akai MPC, SP-404 MKII, Maschine+, S2400, and the Venus Instruments Veno-Orbit. Software targets include SFZ, SoundFont 2, Decent Sampler, and Ableton Sampler. You can also add custom profiles for hardware that isn't built in.

Can SampleStack import and build multisample instruments?

Yes. SampleStack imports SFZ and Decent Sampler instruments, including .dslibrary archives and keyswitched libraries, and preserves source metadata that other tools discard. You can also build an instrument from a folder of one-shots, then export to SFZ, SoundFont 2, Decent Sampler, Ableton Sampler, disting EX and NT, or 1010music Bitbox, thinning zones by pitch, round-robins, or velocity layers to fit a hardware target's limits.

Does SampleStack modify my original files?

No. All edits and conversions are non-destructive. SampleStack stages changes in a working area and only writes new files when you explicitly export. Your originals stay untouched.

What audio formats does SampleStack work with?

SampleStack reads and writes WAV, AIFF, FLAC, and other common formats. It converts between sample rates (44.1, 48, 96 kHz), bit depths (16, 24, 32-bit float), and channel layouts (mono and stereo) using SoX-based resampling, so you can prep for any module without quality loss.

How do I prepare samples for the Morphagene?

The Make Noise Morphagene wants 32-bit float WAV at 48 kHz, stereo, with reels under about 174 seconds. SampleStack ships with a Morphagene profile that validates the format, converts whatever needs converting, and writes splice markers so each sample plays back correctly as a reel.

Can I batch-convert an entire sample library?

Yes. Apply a target instrument profile to a folder of any size. SampleStack validates, converts, renames, and organizes every file in a single pass, ready to drop onto your SD card.

How is a sample manager different from a DAW?

A DAW (Logic, Ableton, Pro Tools) is built for making music inside the software. A sample manager handles the file-level work that hardware needs: SD card layouts, manufacturer-specific folder structures, splice markers, and conversion edge cases that DAWs don't address. SampleStack also drags samples straight into a DAW, so it works alongside one rather than replacing it.

Which DAWs does SampleStack work with?

Any DAW that accepts audio files dragged in from Finder, including Ableton Live, Logic Pro, FL Studio, Bitwig Studio, Studio One, Cubase, and Reaper. SampleStack's companion window sits beside the DAW so you can audition a sample and drag it onto a track. Multisample instruments export to Ableton Sampler, Bitwig and Studio One, SFZ, and Decent Sampler.

Does SampleStack detect BPM and key?

SampleStack detects the BPM of loops automatically and the root note of pitched samples when you build an instrument. Musical key is a field you fill in yourself; SampleStack does not detect it.

Can I use SampleStack with my Splice samples?

Yes. Add your Splice folder as a library and SampleStack browses it in place. Organize with tags, ratings, and categories rather than moving files, so the Splice app keeps track of them, and copy samples to a hardware collection when you want them converted for a device.

How much does SampleStack cost?

SampleStack is on the Mac App Store with a 7-day free trial. After the trial you can choose an annual subscription or a one-time lifetime purchase, whichever fits your workflow.

What are the system requirements?

SampleStack is a native macOS app built with Swift and SwiftUI. It requires macOS 15.6 (Sequoia) or later, and runs on both Apple Silicon and Intel Macs.
