INSTRUMENTS AND EFFECTS, BUILT IN
Finish a song without buying another plugin.
Synths, vocal tools, and mixing and mastering effects come with Harmonic Pro Studio, made for the same song you are writing. Many of them read its key and chords, so they work with the music instead of around it.
-
SYNTH
Sonic
A four-layer synth made for EDM: supersaws, basses, plucks and pads, with filters, modulation and effects all on one face.
-
SYNTH
Harmonic Classic
Six voices of warm analog sound: three oscillators, a ladder filter, poly mod and 130 patches.
-
VOCAL
Voice Factory
One vocal in. A stack of harmonies out, on your song’s chords.
-
VOCAL
Voice Front
A complete lead-vocal chain in one plugin, with five simple controls or every stage in view.
-
VOCAL
Auto Pitch Live
Pitch correction your singer hears while recording, less than 3 ms late, in the key it hears in the singing.
-
EQ
Advance EQ
An automatic EQ that listens to your track, knows your song’s notes and chords, and tells you why it makes every move.
-
DYNAMICS
Press
A smooth, classic-style compressor with two big knobs, a glowing VU meter and warm analogue colour.
-
DYNAMICS
Pump
The bass ducking under the kick, the pumping pad, the gate and the swell. On the beat, on another track’s sound or on its notes.
-
REVERB
Harmonic Space
From a subtle room to an endless shimmering cathedral. The studio reverb of Harmonic Pro Studio.
-
STEREO
Enhancer
Set the stereo width of the lows, the mids and the highs on their own, and stay safe in mono.
-
RESTORATION
DeNoiser
Learn the noise. Keep the sound.
-
MASTERING
Ceiling
A true-peak limiter that makes your master loud and tells you, in plain words, if it is ready for streaming.
The full suite is in the Studio edition. Free and Home include a smaller set of effects and instruments. Compare editions →
FINISH AND DELIVER
Finish it. Send it out.
When the song is done, Harmonic Pro Studio hands over everything people ask for: the mix, the stems and every version of the song, at the right loudness and in the formats they want. For a label, a sync library, a mastering engineer or the artist.
- My Song - Main.wav The mix −14 LUFS
- My Song - Instrumental.wav No vocals −14 LUFS
- My Song - A cappella.wav Vocals only −14 LUFS
- My Song - TV mix.wav No lead vocal −14 LUFS
- My Song - Vocal up.wav Lead vocal louder −14 LUFS
- My Song - Vocal down.wav Lead vocal quieter −14 LUFS
Every version in one click
The mix, then Instrumental, A cappella, TV mix, Vocal up and Vocal down, each at the mix’s level. Mark your vocal tracks once.
Stems, your way
One file per track, taken after the fader, before it, or dry, ready for a mix or mastering engineer.
Ready for streaming
Export to a loudness target with a true-peak ceiling, or to a peak level, so the song is ready for streaming services.
Two formats at once
WAV, AIFF, FLAC, MP3, AAC or OGG, up to 192 kHz. Write a WAV master and an MP3 to share in the same export.
Section by section
The whole song, the loop, a selection, or each marker or section as a file of its own. Title, artist and ISRC go inside the file.
A queue and a history
Line up several exports and run them in one go. Every export is remembered, and runs again on the song as it is now.
Stems, the delivery pack and the export queue are in the Studio edition. Every edition exports a stereo WAV or MP3 mix.
NIMI · YOUR AI IN THE STUDIO
Full studio control. Live sound generation.
You have the ears; Nimi knows the theory. Say what you hear in your own words, no music theory needed. Nimi has full control of Harmonic Pro Studio: every track, instrument and effect, the Arranger band, the mixer, the settings and the export. And it generates sound live for your song: one-shots, audio loops, parts and vocals, at your tempo, in your key and over your chords.
- Full studio control
- Anything in the studio, in your own words: build a session, route a vocal bus, duck the bass under the kick, write a progression, export the stems.
- Live sound generation
- No more loop packs: ask for a one-shot, a loop, a part or vocals. It is generated for this song, and every sound you keep is yours forever.
- It listens first
- It renders and measures your mix: loudness, balance, width and the tracks that fight each other. Then it proposes moves. Nothing changes until you say yes.
- You stay in charge
- Every change it makes is one undo step, marked as the AI’s in the song’s history. Anything that would delete something asks you first.
Nimi runs in the cloud, so it is an optional monthly plan and needs an internet connection. Your audio is sent only when you agree. What you write, play, arrange and edit is yours.
Everything Nimi can do →Make the chorus lift, and bring the lead vocal up 2 dB there.
Done. In the chorus, bars 17 to 32:
- The band plays its Main B groove, with a fill into it
- Lead Vocal held 2 dB higher, ramping in over a beat
- The pads widened a little, the mix still safe in mono
Three steps. Press Ctrl+Z to take any of them back.
ADVANCED TIME STRETCH
Any tempo. The same sound.
Our own time stretch, built for music. Drag a clip’s edge to fit it to the bar, or let Auto-Warp find a loop’s tempo and line its beats up with your song. Hits stay on the beat, notes stay in tune, and the stereo image stays where it was.
Everything about time stretch →- 0.25–8×

Beats
For drums and loops. Hits stay sharp and land on the beat.
-

Tones
For vocals, bass and keys. Notes stay clear and in tune.
-

Texture
For pads, ambience and noise. The sound stays smooth.
-
MODE
Repitch
Like tape: speed and pitch move together.
Pitch and formants
Change the pitch without changing the tempo. Formant Preserve keeps a voice sounding like the same singer.
Auto-Warp
Reads the tempo from the file, the loop’s length or by listening, then lines up its beats. If it isn’t sure, it changes nothing.
Rendered when ready
Once you stop editing, a stretched clip plays from a file made in the background: the same sound, for a fraction of the CPU.
Drag to fit
Stretch a clip with the Time Warp tool, and every change is one undo step.
ADVANCED AUDIO EDITOR
Repair, retune and polish any recording.
Double-click an audio clip and it opens in the Audio Editor: a waveform, a spectrum and a pitch view of your recording. Select a range, right-click, and clean it, level it or tune it. Every process stays editable, and nothing is written until you Apply.
- De-noise, de-click, de-hum, de-clip, de-ess
- Spectral Patch: draw around a cough and heal it
- Note-by-note pitch editing for vocals
- Level ride, normalize to LUFS, align doubles
