Card 3 (Lead):

n("0 2 3 5 3 2").scale("C4:minor").s("triangle").gain(0.5)

Card 4 (Pad):

n("0 3 7").scale("C3:minor").s("sawtooth").lpf(600).room(0.8).slow(4).gain(0.4)

Tips¶

Combining Patterns¶

Stay in key: Use the same scale (e.g., C:minor) across cards
Frequency separation: Bass low, melody mid, ambient spread
Dynamics: Use .gain() sliders for real-time mix control

Modifying Patterns¶

Start with a pattern and experiment:

Change .fast(2) to .fast(4) for double speed
Swap scales: C:minor to C:major
Add effects: .room(0.5) or .delay(0.25)
Add sliders: .lpf(slider(800, 100, 4000))
