Engine Room
Pick a left-hand engine and a right-hand pattern, run them over a frame in any key, and build independence. Everything exports as MIDI.
Rhythm map
How to read Engine Room Symbols, the rhythm map, left-hand tokens, colours, practice tools, and T1–T20 with a demo of each
Symbols
Difficulty is shown from one to four. T1–T20 identify rhythmic technologies; click a T chip to see its card.
The rhythm map
Two bars in sixteenth notes. Dots mark note starts; the highlighted column is the playhead. The timeline shows the selected clave or rhythm.
Left-hand tokens
R is the bass note; 3, 5, 6 and 7 are chord tones; 8 is the octave and C a chord.
Colours and sounds
Blue is the left hand, orange the right. Switch Colour to show chord tones.
Displacement and feel
Shift moves a hand by sixteenths. Feel places it ahead of or behind the grid in milliseconds.
Practice tools and support tests
Mute a hand to play it yourself, train tempo, or let the click drop out and test your time.
The technology index, T1–T20
Piano roll
