Trombone.

Written as MIDI. Played as a trombone.

Write the line in your piano roll and get a trombone back on the track — connected where the notes tie, warm low down, open and brassy when pushed.

Hear it.

Listen for the joins. Where two notes were written legato the slide carries one into the next; where they were separated, each gets its own attack.

The part is the melody of After You’ve Gone — 34 notes at 138 bpm, the one the chooser on /sources plays on every instrument. This is the trombone’s render as it came back: nothing played, sampled or edited.

The chooser’s melody — 34 notes at 138 bpm — rendered as trombone. Nothing played, sampled or edited.

§ 02 · In your DAW

MIDI in. Audio out.

Write the part in the piano roll you already use — Logic Pro, Ableton Live, FL Studio, REAPER, Cubase and Studio One — with dø1 on the track, or upload a .mid at /tools/sources. Notes, timing and velocity are read as written.

What comes back is a trombone take: dry, close-mic, 24-bit / 48 kHz, on the track it came from. Usually 20 to 60 seconds. Render again and you get a different take.

Rendering in the browser is free with an account — 120 credits a month, 10 per 30-second render. The plugin is part of Pro, $12 a month: 2,000 credits, dø1 (AU and VST3) and Dø Desktop, which installs it.

The slide is the point.

A trombone has no valves. Moving between notes is a continuous change of tube length, and the player decides how much of that journey you hear — a clean break, a soft glide, a deliberate smear. A sampler has one recording per note and nothing in between.

Like every brass instrument it brightens as it is pushed: round and vocal at mezzo-forte, blaring at fortissimo. Velocity in the MIDI drives that, so a swell written as rising velocities comes back as a tone opening up, not a quiet take turned up.

Questions.

Does it do legato?

Yes. Overlapping or tied notes render as a connected line; gaps render as separate attacks.

Can I write a trombone section?

Render each chair as its own part and mix the stems. The Sing, Sing, Sing demo on /sources is four rendered trombones summed.

Is it free?

Rendering in the browser is free with an account — 120 credits a month, 10 per 30-second render. The plugin is part of Pro, $12 a month.
