Hydrogen vs Microtonic

Hydrogen is a drum sequencer and sample-based synthesizer for pattern-based rhythm programming, songwriting, or use with an external MIDI keyboard or sequencer. Its sequencer supports unlimited patterns that can be chained into songs. The pattern editor adjusts per-note properties such as velocity and pan, and humanization functions cover velocity, timing, pitch, and swing. Hydrogen imports WAV, AU, AIFF, and FLAC samples and provides downloadable drumkits through a sound library manager. It supports MIDI and OSC automation, time-stretching, and pitch shifting. Audio driver support includes JACK, ALSA, PortAudio, and OSS; exports include WAV, AIFF, FLAC, OGG, MIDI, and LilyPond. Hydrogen is free under GPLv2+ and runs on Linux, Windows, and macOS. Listed Windows downloads support Vista and later, while the current macOS release supports 10.14 and later. The project describes use for home practice, studio work, and live performance. Its FAQ says there are no current plans for an LV2 plugin version.

Microtonic is a VST/AU drum and percussion synthesizer paired with a pattern-based drum-machine engine for Windows and Mac. It generates sounds in real time through synthesis rather than samples or pre-rendered waveforms. Eight drum and percussion channels can play from a MIDI keyboard or sequencer, while patterns stay synchronized with a host sequencer. Sound-design features include over-sampled oscillators, sample-accurate triggering, morphing, smart alteration, and randomization. Factory sounds and patterns are included, and Patternarium provides thousands of computer-generated presets for royalty-free use. Presets can be heard online, downloaded or copied into Microtonic, and voted on. The Mac release includes a standalone application plus VST 2.4, VST3, and Audio Unit 2 plug-ins. Windows has no standalone application and requires a suitable VST host. Microtonic costs 99.00 USD as a one-time purchase, with a 21-day trial beginning at first launch in a host sequencer. Purchases include usage rights, support, and service updates.
