Multiple Tempos & Adding Patterns

Patterns can play at different tempos at the same time, and you can combine patterns together.

Different tempos with fast and slow

Combine patterns at different speeds with a comma:

strudel
sound("hh hh hh hh, bd*2, sd")

Each comma-separated part can have its own tempo! Listen to how the bd plays twice as fast as the hi-hat.

Add patterns together with add

add combines patterns by adding their values. This is great for notes:

strudel
note("c d e f").add(note("<0 1 2>")).sound("gm_vibraphone")

The second pattern shifts the first up by 0, 1, or 2 scale steps... wait, let's try numbers instead:

strudel
note("c d e f").add(3).sound("gm_vibraphone")

Add a whole pattern to another

strudel
note("48 52 55 59").add("<0 12 24>").sound("piano")

Here <0 12 24> adds 0, 12, or 24 semitones to every note - raising the whole line an octave at a time!

Parallel or add?

• Comma - plays patterns at the same time (parallel).
• add - merges values into one pattern.

TL;DR

• Commas play patterns at the same time, each with its own tempo.
• add combines values into one pattern.
• note("...").add("<0 12 24>") transposes by octaves.
