WoodShed Music

Turn any recording into your practice room.

Loop the hard parts, slow them down without changing pitch, put the whole chart in your key, pull the band apart — and train until it's yours. All on your own device, all offline.

Section 01

The Player.

One screen with everything a working musician reaches for: the waveform, the changes, the loop, the trainer, the band, the record button. Shown here in WoodShed's Sheet Music theme — engraved ink on ivory.

On Green Dolphin Street — WoodShed
WoodShed Player in the Sheet Music theme: a gold and slate waveform mid-playback with named section markers Head and Solo, a bar-numbered chord lane underneath, and the full transport.
1The playhead splits the song — played gold, still-to-come slate
2Pin the form with named markers
3The chord lane rides under the audio

01 · Waveform

See the song you're hearing.

Import anything — Files, iCloud Drive, AirDrop, your Music library — and WoodShed draws it as a clean, musical waveform. Double-tap to jump, pinch to zoom, and drop named markers on the map: Head, Solo, wherever the form turns.

Beat detection reads the song's own pulse (♩ = 132 here, and it knows it's in 4/4), so everything downstream — the bar grid, the count-in, the snap — lines up with the music.

On Green Dolphin Street — WoodShed
The chord ribbon in Snap mode: detected chords Cmaj7, Cm7, D7, G7, Dm7 laid bar by bar under the waveform, with the detected key badge reading C major.
1The changes, bar by bar — detected on your device
2Snap to the waveform, or let Reader mode scroll
3It finds the key — ♪ C maj

Live — this one's playing

The changes slide under the playhead, and every beat ticks as it lands — this is Reader mode, rebuilt for the page. It follows the rain's tempo, so the slider below slows this too.

02 · Chord detection

It hears the changes.

WoodShed listens to the record and writes the chart: a bar-numbered chord lane that follows the music as it plays — Cm7 · D7 · G7, right where they sound. It names the key while it's at it.

Reader mode scrolls the changes past you like a bandstand chart; Snap mode locks them under the audio that sounds them. Every chord is editable — your ears outrank the model, always.

On Green Dolphin Street — WoodShed
An A/B loop engaged over the bridge: the region shaded gold with Loop Start and Loop End flags, the loop toggle tinted, and three saved loops waiting.
1A and B, set on the fly
2Tinted while it loops
3Save the hard parts by name
The Saved loops panel listing The bridge, Turnaround, and Last A with their time ranges — tap to load, drag to reorder.

03 · Looping

Loop the hard parts.

Set A and B without stopping the music and the passage spins seamlessly — the loop lives in the native audio engine, so the seam never hiccups. Nudge either end to the beat until the loop is exactly the phrase.

Then save it by name — “The bridge”, “Turnaround”, “Last A” — and tomorrow's practice starts where today's left off.

Try it on the rain Behind this card the storm is looping too — drag the A and B clamps on the staff to move the rain.

On Green Dolphin Street — WoodShed
The Key trainer mid-run: the loop spinning, a readout pill showing C to D pass 1, and the floating Now/Next card promising the next key.
1Now → Next, always in the corner of your eye
2C → D · pass 1 — hands-free

04 · Loop trainer

Practice that pushes back.

Arm the Speed trainer and every pass nudges the tempo — 70% to full, two points at a time, until you're playing it at speed without noticing the climb.

Arm the Key trainer and the loop walks the keys for you: up a whole step each pass, up in fourths, down in half steps — whatever interval you set, for as many passes as you want to sit in each key. Stop, and the song returns to where you started.

Trainer — WoodShed
The Trainer hub: a Speed section with From, To, Step and Every steppers, and an armed Key section set to an interval of a major 2nd every pass, with the path preview C, D, E onward.
1Arm it — the loop does the rest
2Pick the interval — the sign is the direction
3It shows you where you're headed

04 · The hub

One dial for both trainers.

Speed and Key live in one hub and run together if you dare — ramp the tempo while the key walks. The Now → Next card floats over the waveform so tomorrow's key never ambushes you.

The playback row with tempo pulled to 85 percent and transpose at minus 2 — the chord lane and key badge re-spelled into B flat.
185% — slower, same pitch

05 · Tempo

Half-speed, full pitch.

25% to 200% with studio-grade time-stretching — no chipmunk, no smear, no drift, and magnetic detents at the useful stops. Slow the solo until you can hear every grace note, then walk it back up.

Try it on the rain

100%

The drops fall later — but each one is still the same drop. Tempo 100% · Pitch +0 st, always.

On Green Dolphin Street — WoodShed
Transpose at minus two half steps: the readout shows −2 · B♭ maj and the entire chord lane — B♭m7, C7, F7, B♭maj7 — has re-spelled itself into the new key.
1−2 · B♭ — into your horn's key
2The whole chart re-spells itself

06 · Transposition

Any song, your key.

Six half-steps either way, artifact-free. Drop “Green Dolphin” a whole step and everything follows — the chord lane, the key badge, the trainer's key path — re-spelled into B♭ like the chart was written there.

Tenor and soprano players: that's concert pitch handled. Singers: find the key where the bridge stops hurting.

On Green Dolphin Street — WoodShed
The stems mixer: five channel strips — Main, Drums, Bass, Other, Vocals — with the Bass solo lit and faders set to a live balance.
1Solo the bass — steal the line
2Flip between the original and your stems
3Balance the band around you

07 · Stem separation

Split the band — on your device.

Two, four, or six stems — drums, bass, vocals, the rest — separated by a neural engine that runs entirely on your Mac or iPad. Nothing uploads. Ever. The cloud never hears you practice.

Solo the bass to transcribe the line. Pull the drums and keep time yourself. Mute the sax and the chair is yours.

Try it on the rain

Four rains are falling, one per stem. Silence a color and listen to what's left.

On Green Dolphin Street — WoodShed
The instant backing track: the Vocals fader at zero, the rest of the band balanced, and the Export stem mix button in the mixer header.
1Vocals to zero…
2…and export the mix exactly as you hear it

08 · Backing tracks

Print your backing track.

Slide the vocals — or any stem — to zero, balance what's left, and Export Stem Mix bounces a single file mixed exactly as you hear it. Faders, mutes, solo — what you heard is what you get.

An instant play-along for the gig, the classroom, or the shed. Loop exports work the same way: just the phrase, as audio.

On Green Dolphin Street — WoodShed
The record arm tray open on the Player: a live green level meter reading −8 dB with peak hold, the capture gain slider, a Count-in one bar chip, and the red Start button — with a use-headphones advisory beneath.
1The meter reads what lands on disk
2Record-along, right on the transport
3Counts you in — one bar ahead

09 · Record

Play along. Keep the take.

Tap ● and the arm tray springs open — no modal, the Player stays live. Set your level on a real meter (it reads exactly what lands on disk), dial in capture gain, and Start counts you in at the song's own tempo.

WoodShed records your instrument and the backing as separate layers, so in Review you balance the two before it saves one clean take — straight to your Recordings shelf.

Section 02

The Staff View.

WoodShed engraves the chart straight from the audio — a Real-Book-style page in the hand-inked jazz face, rhythm slashes and all. And unlike the book on your stand, this one plays.

On Green Dolphin Street — Staff View
The Staff View mid-playback: a jazz-engraved chart with rhythm slashes, the current bar highlighted, the beat cursor inside it, and Head and Solo markers pinned to the staff.
1The current bar lights up as it plays
2Your markers land on the chart too
3Petaluma — the hand-inked jazz face

01 · Follow the chart

The chart that follows the music.

Press play and the page reads with you: the current bar carries a highlight, a beat cursor walks the measure, and the page turns itself — the chart scrolls to keep the music in view.

It's the same playhead as the Player, so your loops, markers, and trainers all work from here. Practice from the chart; the audio follows.

On Green Dolphin Street — Staff View
The Staff View transposed down two half steps: the entire chart re-engraved in B flat — key signature, every chord symbol — with the playback row reading 85 percent and minus 2.
1Down two — the chart re-engraves in B♭
2−2 · B♭ — right on the stand

02 · Player controls

Transpose the page, not just the sound.

The playback row rides the bottom of the chart: pull the tempo to 85%, drop the key two half-steps, and the whole page re-engraves — key signature, every chord symbol, the trainer's key path.

Horn players: the chart finally reads in your key while the record plays in it too.

On Green Dolphin Street — Editing
Edit mode on the Staff View: a Dm7 selected with a glow, and the docked chord palette inspecting it — root picker on D, quality on m7, slash bass toggle, Add and Delete chord.
1Tap a chord — it glows, the palette inspects it
2Root, quality, slash bass — your call
3The Meter tool re-bars from any measure

03 · The editor

Your ears outrank the model.

Hit Edit and the chart becomes the editor: tap any chord and the docked palette opens it — root, quality, slash bass. Tap an empty beat to drop a chord in; drag one to move it. Undo covers everything until you Save.

The Meter tool re-bars the song from any measure, and tempo lives right on the playback row — the whole chart, correctable at speed.

Section 03

The Track Editor.

Cut the count-off, silence the false start, paste the chorus twice — non-destructive until the moment you save, and every change audible instantly.

Edit — On Green Dolphin Street
The Track Editor mid-session: a span cut to silence with seam markers, the chord lane above the transport, an armed Undo, a 1.5 second fade-in and a plus 2 dB gain trim with one-tap Normalize.
1Cut to silence — seams marked, nothing lost
2Copy · Paste · Cut · Undo — surgery with a safety net
3Fades on the ends, baked only when you Save
4One-tap Normalize

01 · Cut · Copy · Paste

Edit the take, keep the original.

Select to the beat (snap knows the bar lines), then cut — close the gap or leave silence — copy, paste at the playhead, undo, redo. Every edit re-renders from the original audio, so there's no generational loss, ever.

Fades, gain, and one-tap Normalize ride the output stage; audition slower without touching the saved audio. Then Save — or Save as Copy and keep both takes.

Section 04

The Metronome.

A sample-locked click with a face worth watching — and a trainer that raises the tempo while you're not looking.

Metronome — WoodShed
The metronome running at 120 BPM: the downbeat blooming gold across a four-beat row, a large tempo dial, and a bench of time signatures, subdivisions, click voices, and presets.
1The downbeat blooms — accents you can see
2Any meter — 2/2 to 12/8
3Save your setups by name

01 · Pulse Deck

A click you can see coming.

The beat row blooms on every click — downbeat gold, the rest quiet — so the accent pattern is visible at a glance. Four voices, subdivisions down to triplets and eighths, tap tempo, and presets for the setups you keep coming back to.

Sample-locked in the native engine, so the click never drifts — and when you record from here, the count-in reads the song's own detected tempo.

Metronome — Tempo trainer
The tempo trainer mid-climb: the dial at 84 BPM with the readout 'To 120 BPM, next step in 1 bar' and the trainer card armed with its From and To steppers.
1Already climbing — 80 → 84
2Next step in a bar — keep playing
3From, To, and the pace — then go

02 · Tempo Trainer

The climb you don't notice.

Set From, To, and the step, and the trainer raises the tempo while you play — a nudge each bar, 80 to 120, until the readout says you've arrived. No stopping, no touching the dial; the click leads and you follow.

It's the metronome's cousin of the Player's Speed trainer — the same idea, aimed at scales, rudiments, and everything you practice without a record.

Section 05

The Tuner.

A chromatic lantern: the note at the heart, your pitch orbiting it, and a green bloom when you land.

Tuner — WoodShed
The tuner locked on A4: the note glowing green, the readout at 0.0 cents in tune, with instrument transposition keycaps for C, B flat and E flat and the A4 reference at 440 Hz.
1Locked — the lantern blooms green
2B♭ and E♭ horns read in their own key
3Calibrate the A4 reference
The tuner reading 19.8 cents flat: the pitch orb sitting amber to the left of the target ring.

01 · Pitch Lantern

Land the note, watch it bloom.

Your pitch orbits the target — amber when you're shy, red when you're wide, and a green bloom the moment you lock. Cents on the dial, no squinting at needles.

Saxophonists and clarinetists: flip the keycap and the tuner reads in B♭ or E♭ — concert pitch stays under the hood. A4 is yours to calibrate.

Try it on the rain Two gutters are dripping behind this card — almost, but not quite, together. Rest your cursor over the water and hold still: the drips settle into one pulse. That's what in-tune sounds like.
