Koala Sampler vs Schism Tracker

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.

Schism Tracker is a free, open-source sample-based music composition tool and reimplementation of Impulse Tracker. It provides multitrack editing and MIDI sequencing, with a playback engine based on a modified ModPlug engine intended to improve Impulse Tracker playback. The project says it runs on SDL-supported systems and provides builds for Windows, macOS, and Linux; its download page also lists Wii, Wii U, XBOX, and Mac OS 9 builds. Source code and platform-specific compilation instructions are available, and the repository identifies the GPL-2.0 license. Community help is directed to the #schism IRC channel on Libera.Chat and the #schismtracker channel in TARC on Discord. Bugs and feature requests go through GitHub issues. The latest release listed is 20260524. The free plan is free, with no paid plans or usage limits stated.
