Subsample vs Vaporizer 2

Subsample is a standalone sampler that turns live input or recordings into collections of sounds that can be played from MIDI. It separates and sorts sound events, then maps them to MIDI notes by acoustic similarity without labels, training data, or manual tagging. In live sampling, it captures, trims, analyses, and adds distinct events to an instrument library in real time. For longer samples, onset detection can identify hits and place them on a beat grid at a target BPM. Its processors include filters, dynamics, distortion, radio, vocoder, pitch shifting, time stretching, and quantisation. It accepts WAV, BWF, FLAC, AIFF, OGG, and MP3/MPEG files, and supports MIDI input, OSC, and MIDI control bindings. Audio runs from mono through 7.1, with per-instrument routing and first-order ambisonic capture and playback. Subsample has no graphical interface and runs from a terminal, using YAML files and a MIDI map. It is an early release, and those formats may change. The open-source AGPLv3 license requires source availability for modified versions used as network services; proprietary use requires a commercial licence.

Vaporizer 2 is a free, open-source synthesizer and sampler workstation for Linux, macOS, and Windows. It brings together wavetable, additive, FM, subtractive, and sample-based sound generation, with a granular mode. Four alias-free wavetable oscillator banks support up to 24-oscillator unison. The editor can draw wavetables with Bezier curves, edit cycles, and import Serum- and Icarus-format files. Sampling supports WAV, AIFF, OGG, and MP3, as well as loop points, key tracking, and sample-to-wavetable resampling. The product page lists more than 780 wavetables and single cycles and more than 410 factory presets. Modulation offers 25 sources, 220 destinations, five MSEG envelopes, and five LFOs; MIDI Polyphonic Expression is supported. It is available as a standalone app and in plugin formats including VST2, VST3, AU, AAX, CLAP, and LV2. The README specifies at least 1 GB RAM and a CPU supporting AVX or SSE2. The maker lists lifelong free updates.
