Quanta 2 vs Subsample

Quanta 2 is a granular synthesizer plugin for shaping imported audio samples into playable sounds. Its grain engine can produce up to 100 simultaneous grains per voice and works with AIFF, WAV, Broadcast WAV, FLAC, MP3, and Ogg files in any sample rate, bit depth, or channel configuration. Two virtual analog oscillators and a noise source add other sound sources, with dual filters that can run in series or parallel. Modulation includes four envelope generators of up to 99 steps each, two LFOs, sample and hold, and four assignable macros. Chorus, stereo dual delay, and reverb are built in. Quanta 2 supports MPE controllers, MTS-ESP microtuning, and TUN-format tuning tables. Desktop plugin formats are VST3, AU, AAX, and CLAP; the iPhone and iPad version is AUv3 and is sold separately. A fully functional demo has a 20-minute session timer and disables saving. The listed desktop license is $99 as a one-time purchase, with no subscription or DRM. A 2026 update added real-time recording and additional filter modes.

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.
