This is the heart of ArrONE. Just keep scrolling and watch your recordings turn, step by step, into a finished vocal production at the highest studio standard, all in one program.
Record pass after pass, and ArrONE keeps everything together in one take folder. In your headphones you hear yourself directly, with reverb if you like.
In the take folder you press PITCH. Now every single take gets tuned, not just one. The Tune slider sets how much.
TIMING pulls all takes together, GATE removes the silence between phrases, and BREATH keeps the breath in, quietly.
Now you listen through the tuned takes and mark the best parts. Your lead vocal appears on the track above straight away and plays.
Edit with ArrTune opens the voice note by note: pitch, length, vibrato and level, right on the track. No transfer, no second program.
Create Doubling builds the double from the takes that did not end up in the lead. So these are real voices, sung by you.
You choose how many sing at once, three for example, and ArrONE spreads them across the stereo field. The more takes you sang, the more voices are possible.
Create Choir Instrument turns your takes into an instrument. You play the chords, and the Harmonizer sings them in your own voice, with the words of your lead vocal.
That way the recordings that would otherwise have gone unused become a whole choir in studio quality.
ArrONE is a full DAW as well. Instruments, MIDI and audio, buses, mixer, effects and mastering are all there, so you can take the production all the way to the end right here.
See the offerFirst the untuned original recording, then every pitch twice: with ArrTune and with a high industry standard. Both start from the same raw recording, and all examples are level-matched. You can switch during playback, the position stays the same.
The same recording as above, turned into a choir by ArrChoir. Three engines at the same level. You can switch during playback, the position stays the same.
ZERO responds without delay. HQ works from the learned recording. TAKES builds the voices from your takes.

The plugins are built for ArrONE and run right inside the app. All of them are included in ArrONE.
Channel strip with EQ, compressor, de-esser and a vari-mu stage in one chain. The EQ has up to seven bands and shows the spectrum live.
Delay and convolution reverb in one plugin, in series or in parallel. Both blocks can run in reverse. The delay has ping-pong, tape saturation and ducking, the reverb more than a hundred rooms, halls and plates.
Sampler that loads instruments in the Logic Pro EXS format directly, with all zones and velocity layers. You build your own instruments by drag and drop, and the search covers all your libraries.
Drum sampler for your own kits. Every key has its own settings and a send into the built-in reverb.
A live choir from your lead vocal: you play chords, and four parts plus a pedal voice sing them with the lead's lyrics. Three play modes (live, around, diatonic), three sound engines up to your own takes, plus humanize, portamento and scenes.
Pitch correction for vocals with zero latency. The notes sit on the grid; you drag their pitch, length and vibrato, or let them snap to the key automatically. Plus a gate that turns pauses and breaths down separately.
Hi, I'm Hens Hensen. Originally I just wanted to write a MIDI plug-in – and ended up building an entire DAW around it. It simply happened that way, and the ambition was there. Today ArrONE is my daily tool: every one of my productions is made with it, from the first chord to the finished mix. I work on the program every day and keep extending it. If a feature is missing or something in the workflow bothers you, write to me. Much of what is in there today came about exactly like that: from requests by people who make music with it.

I built ArrONE to save you a lot of busywork. Its structure is thought through from the start: everything connects, from the sum buses down to the stems. You get the final mix in several versions right away, whether instrumental, half playback or live playback, all automatic.
On top of that, plenty of features make producing easier. So you can get back to what it is really about: making music.
Audio and MIDI tracks, clips with fades and crossfades, take folders with comping, piano roll, colour folders, markers, tempo track. Tool field with marquee, eraser and mute, grid chip, auto-scroll, pinch zoom, freely assignable keys. Four DJ effect lanes with regions for hi-cut, low-cut, tempo-synced delay, tape stop, reverse, phaser, volume or one of your own plugins, each drawn as a curve and aimed at single buses or the master.
The lead engine aligns timing and pitch of all takes in a take folder to their common average. The result is doublings that run in sync and can be bounced to a new track. Take folders can be linked as master and slave: doublings and backing vocals follow the timing of the lead vocal. Audio edit removes breaths, clicks and mouth noises. Vocal Space ducks the music under the voice, sidechain from any track.
Video track with clips, photos, titles and motion. Lyrics are stamped onto the time with a keypress, export as LRC. Lyric video with effects straight to MP4.
32 sum buses with names and colours. Channel mixer and bus mixer, both also as separate windows. Inserts, sends pre and post, pre-mix and master. Mix routing with stems, freeze and realtime freeze. Metering on the Logic scale with LUFS.
Audio Unit and VST3 load directly. Plugin presets, plugin roll, blacklist. Plus Melodyne support and support for Softube Console 1. Hardware controllers with channel follow, external synths with MIDI clock and audio return. Low-latency direct path for playing in.
Stem separation into vocals, drums, bass and rest with the free add-on package. Tempo detection and follow tempo via varispeed. Import as track or take folder, compressed formats included.
Mixdown at the push of a button, mix variants as instrumental, half playback, live playback and full playback, stems export. Play from cursor or selection with pre-roll, cycle, transport window, song archive as ZIP, day and night mode, help search.
