Drum Room

Play, stop and record

• Green play loops the pattern; yellow stop stops it.
• Red record adds the pads you tap to the pattern while it plays.
• Count-in gives you one bar of clicks first; Quantize snaps your hits onto the beat.
• Undo and redo any change.

Tempo and timing

• Type a BPM from 20 to 300, or tap Tap along with the beat.
• Swing adds a shuffle.
• Click plays a metronome while the beat plays.
• Hold Fill to play the hits set to the fill condition.

Sixteen pads

• Each pad plays one sound and picks it for editing.
• Hit higher on a pad to play louder, or turn on Full Level.
• Note Repeat rolls a pad at the rate you choose while you hold it.
• On a computer, four rows of keys play the pads.

Step sequencer

• One row per sound; tap a square to add or remove a hit.
• Steps sets the pattern length, up to 64. Grid sets the spacing: 1/8, 1/8T, 1/16, 1/16T or 1/32.
• Double repeats the pattern to make it twice as long. Copy, Paste and Clear work on the whole pattern.
• Mute and Solo each sound.
• 64 patterns, in lettered banks A to D with 16 slots each.

Hit Details

Fine-tune each hit of the sound you picked. Drag across a row to set it for every hit:

• Velocity
• Chance
• Ratchet
• Nudge
• Pitch
• Condition

• Condition picks which loops a hit plays on, such as the first loop only, fills only, or 1 of every 4.
• Euclidean spreads a number of hits evenly, with rotation.
• Randomize makes new hits at the density you set; Humanize loosens them so they feel played by hand.
• Shift all hits left or right, or Reverse them.
• Loop length lets one sound repeat on a shorter cycle than the rest of the pattern.

Sound shaping

• Every built-in sound is made by a synth engine you can adjust, with its own controls and a waveform view.
• For any sound: Tune, Attack, Decay, Start, Reverse, a Filter, Drive, Bit crush, EQ, Pan, Volume, and how much Reverb and Delay it gets.
• Vary makes a small change to a built-in sound; Mutate makes a big one.
• Choke groups let sounds cut each other off, like an open and closed hi-hat.
• Rename and recolor any sound, and set its MIDI note.

Mixer

• A console display shows one sound at a time: Low, Mid and High EQ, Pan, Reverb, Delay, Mute, Solo and Volume.
• Master: overall volume, a compressor that glues the mix, a limiter that stops it distorting, and settings for the reverb and delay.
• Skin changes the display colour. Classic shows every sound side by side.

Library and kits

• 30 built-in kits in five styles: Analog, Electronic, Acoustic, Lo-Fi and World.
• Load Kit swaps all 16 sounds and keeps your patterns.
• Generated Kits makes brand-new kits.
• Edit Kit Sounds builds your own version of a kit from any kit's sounds or your samples. Save Kit keeps it in My Kits; Restore Original undoes changes to a built-in kit.
• All Sounds searches every sound.
• My Samples holds audio files you import: WAV, AIFF, MP3, OGG or FLAC.

Song mode

• Chain patterns into a song, set how many times each part repeats, and reorder, duplicate or remove parts.
• Switch from Pattern to Song to play the whole thing. Loop song starts it again at the end.

Record and export

• Record master records everything you play and change as a WAV file.
• Export mix WAV saves the pattern or song as one file. Export stems ZIP saves one file per sound. Export MIDI saves the notes for other music apps.
• Sample from Input records your microphone into the sound you picked.

Projects

• Your beat saves itself as you work, and Save keeps named projects in your browser.
• Export project file makes a backup you can open on another device with Open project file.
• Drill drums sent from Practice Room open as a new project.

Controllers and keys

• Plays from MIDI pad controllers and keyboards in browsers with Web MIDI; the app points you to Chrome or Edge for this.
• Keyboard shortcuts on a computer: Space plays and stops, Enter records, arrows pick sounds and patterns, M mutes, K solos, hold G for Fill, Ctrl+Z undoes and Ctrl+S saves.
• A built-in How to Use guide covers every section.
