cymfonic · humanizer

voicings follow your harmony.
rhythm and phrasing follow you.

master track gives the chord. you decide how it plays — which chord tones, in what rhythm, at what velocity, in what voicing. capture a phrase once and it works in every key, against every chord, for the rest of the song.

how it works
  • master sends the chord

    harmonyengine broadcasts the current chord and key in real time. humanizer listens, every buffer.

  • you send the articulation

    place chord-tone degrees on humanizer's piano roll. note position is your rhythm. note velocity is your velocity. note length is your length.

  • every change is automatic

    change the chord or key on the master and every voicing updates in the same buffer. no midi rewriting. no transposition.

  • one piano roll, every key

    phrases are degree-based, not pitched. a pattern written over Cmaj7 plays cleanly over F♯m or D7 or anything else the master throws at it.

what you shape
  • voicings

    closed, open, drop 2, drop 3, with inversion. choose the texture per region.

  • range constraint

    fold every voice into a custom midi range. stack three instances at low / mid / high and one piano roll pattern becomes a full arrangement.

  • humanisation

    timing jitter, length variation, velocity remap. four sliders. the difference between programmed and played.

  • phrase library

    capture once. tag, save, recall. phrases follow whatever chord is current, in any project, in any key.

phrase library

capture once. play in every key.

humanizer phrases are stored as degree patterns, not pitches. capture a four-bar arpeggio over Cmaj7 today. drop it into a song in F♯ minor tomorrow. it plays. it follows. it voices.

  • capture from the piano roll — arm the region, play, lock. the loop crossing commits the phrase.
  • tag, save, browse — tags are folders. save once, find it anywhere on disk.
  • the seven-lane grid — degree i through vii, violet note blocks, animated playhead. visible at a glance.
  • .hephrase on disk — readable json, version-controllable, trivially backed up.

the small movements that make it sound played.

three sliders and a velocity range. that's the difference between programmed and performed.

questions

things people ask.

do i write chord progressions in humanizer?

no — that's harmonyengine. you write roman numerals on a single master midi track, and harmonyengine broadcasts the chord state to every linked plugin in your daw. humanizer reads that state and turns it into voiced midi. think of harmonyengine as the harmonic score and humanizer as the part-writing.

do i need harmonyengine to use it?

yes. humanizer is a harmonyengine plugin — it has no chord data of its own. without a harmonyengine master track in the same daw session, humanizer passes midi through unchanged. the two are designed to be used together.

which voicings are supported?

closed, open, drop 2, drop 3, with inversion. closed packs every chord tone into the tightest cluster. open spreads them an octave. drop 2 and drop 3 are jazz comping voicings that pull the second- or third-highest voice down an octave for a wider, more orchestral spread. inversion shifts which chord tone sits in the bass. you choose the voicing per region — different sections, different textures, all from the same piano roll input.

how does the phrase library work?

arm a region, play a pattern over the master's current chord, hit lock. the phrase is captured as a sequence of degrees — not absolute pitches — so it survives any chord change, key change, or modulation that comes after. tag it (arp, strum, bass, anything you like), save it as a .hephrase json file, recall it from any project on the same machine. the tag is the folder. the filesystem is the library.

is this a one-click chord generator?

no. humanizer is compositional scaffolding — it doesn't write the music, it makes the music you wrote playable. you decide which chord tones sound. you decide the rhythm. you decide the voicing. the plugin handles the mechanical translation of your harmonic intent into voiced midi, sample-accurate, in real time. we provide the bones. you bring the soul.

can i run multiple instances?

yes — it's a core use case. stack three humanizer instances on three tracks: one range-constrained to C2–C3 for bass, one to C3–C5 for comping, one to C5–C7 for pad. a single piano roll pattern voices itself across the full register. one harmonic source, full orchestral spread, no duplicated midi.

what daws and platforms are supported?

vst3 and au formats. windows and mac. tested in reaper and ableton live. logic pro support arrives with the au build. cubase, studio one, and bitwig are vst3 hosts and should work without ceremony — let us know if anything misbehaves.

what's the timing and velocity control like?

four parameters, per region. timing jitter randomises note-on positions in a ±20ms range. length variation randomises note-off positions by 0–20% of the original length. velocity remap stretches incoming velocities into a per-region min / max window. fixed delay offsets every output event by a chosen amount for offsetting layered instances. all four are independent. all four save with the project.

updates

humanizer launches alongside harmonyengine v1.0 — vst3 and au, windows and mac, same release. sign up to hear when the closed beta opens, and to be first in when we ship.
