Koala Sampler vs Serato Studio

Koala Sampler records sounds through a device microphone or imports audio for making beats and tracks. It can capture up to 64 samples and includes a high-resolution sequencer, keyboard mode, quantization, swing, and effects. Projects can be exported as WAV loops or tracks; the iOS version can also export Ableton Live Sets. MIDI control and Ableton Link support external control and Wi-Fi jamming. Optional in-app purchases add more tools: Samurai includes time-stretch algorithms, a piano roll, auto-chop, a three-band EQ, a polyphonic synth, and MIDI output. Mixer adds four channels, a main bus, and five effect slots per channel; its external plugin hosting is available on iOS, Mac, and Windows, but not Android. Koala Sampler is listed for Android, iOS, Linux, macOS, and Windows. Desktop builds for Mac, Windows, Linux, and Raspberry Pi are free for now, although the Windows build is in beta. The iOS app costs $4.99, paid once, with in-app purchases sold separately. The maker says mobile apps do not require an account and keep projects and audio on the device.

Serato Studio is beat-making software for creating beats and custom DJ edits, with a workflow aimed at producers and DJ users. Its Sample Deck can sync samples to project BPM and key, chop them, separate stems, and apply time stretching, key shifting, reverse and effects. Real-time stem separation can split tracks into acapella, melody, bassline and drum parts. Studio includes a step sequencer and more than 190 instruments, including bass, keys, synths, pads, percussion, guitars and orchestral sounds. It supports VST3 and Audio Unit plugins, MIDI hardware mapping, Serato DJ crates and FX plugins. Users can export tracks, mixes, loops or individual drum pads as separate audio files. Studio runs on macOS and Windows and requires a Serato.com account. Free mode is limited to one audio track, four decks and four scenes, with automation disabled. The Subscribe plan costs $9.99/mo; the separate Buy plan is listed at $149 a month.
