Tuner, metronome, and delay calculator; peak / LUFS metering, spectra, room tone, and A/B loudness; tone generation and sample-rate conversion; a sample editor with beat slicing, a sample transformer, and DJ Blend for crafting the transition between two tracks.
A QWERTY-playable keyboard with MIDI export, a live monitor, a device recorder, a controller mapper, an audio-to-MIDI transcriber, a MIDI-to-score generator, and a drum-beat machine.
Creative MIDI generators — counterpoint machinery, cellular automata, Euclidean rhythms, a Markov continuator, L-system growth, orbital polyrhythms, a Turing-machine looper, WFC melodies, Perlin drift, chanted poetry, word melodies, lead-sheet arpeggios, tree outlines, and more. Key-locked from pentatonic to 12-tone rows, exporting .mid with GM sounds.
A playable synthesizer per method across six tiers — the canon, modulation and shaping, physical models, spectral, voice, and the experimental fringe — plus a modular patchbay you wire yourself. Includes DX7-style six-operator Advanced FM with three dozen presets, and a playable Shepard tone. Play any of them from a connected MIDI controller, not just the keyboard.
An interactive music-theory track from fundamentals through harmony into jazz — plus ear-training drills, psychoacoustic illusions, a full microtonal wing (EDOs to maqamat to Scala files), an algorithmic-music history with a playable live-coding pattern demo, music-tech explainers, and the online music community.
Learning tracks for Pro Tools, Ableton Live, Logic Pro, Cubase, Digital Performer, Renoise, REAPER, Bitwig Studio, FL Studio, and Tracktion Waveform — shortcuts, docs, and creators for each. Plus the retro wing: classic DAWs and trackers from the Amiga to early Windows, and game-console sound from the 8-bit era to the disc era.
