Make music with math!

  • Welcome to FuncBud, the generative sequencer that transforms simple mathematical functions into musical patterns.

  • Create, chain, and repeat functions to generate complex sequences.

  • A simple x + 1 function sequences all notes in the scale sequentially.

  • Discover infinite possibilities by experimenting with different formulas and combinations.

Build your math functions

Build your math functions

  • The function builder supports arithmetic operations: addition, subtraction, multiplication, and division.

  • Advanced operations include square, square root, sum, and product calculations.

  • Newly created functions are automatically saved and accessible across all instances.

  • Function results are stored in history for use with sum (∑) and product (∏) operations.

  • ∑3 sums the last 3 results, while ∏3 calculates their product.

  • Use conditionals and random functions to add controlled unpredictability.

Define your limits

  • Generate notes within the current key and scale, bounded by minimum and maximum octaves.

  • Set key, scale, and octave ranges from the top interface.

  • Control sequencer behavior with rate, gate length, gate variety, velocity, velocity variety, and swing parameters.

  • Enable loop detection in settings to automatically break infinite loops.

  • Manage functions easily: mute by swiping left, delete by swiping right.
