Lagged Lights

This file demonstrates how to extract impact data from DOPs and create lighting effects using CHOPs.

Python and CHOP Waveforms

How to generate waveforms with Python or CHOPs in Houdini.

Impact Chop Lights

The Dop Chop Lights node can look at any DOP network, and create lights based on impacts.

Arpeggio

Generation of arpeggio for .chan output.

Synth

Library of CHOPs used to create synthetic sound and music.

Piano

A model of a piano keyboard in SOPs. You can use the chopcf() expression to play the keys.

Ramp Noise

This project uses Noise CHOP and a ramp to generate noise, then applys it to a geometry's points.

Musical Scales

Using CHOPs to generate a MIDI file.

Convert Audio to MIDI

Running audio through a Pitch CHOP will return the frequency and the volume. You can use this data to then generate MIDI or other computer generated sounds and music.

Oscillator

Copy stamping with oscillations using the math behind pitch.

Wave CHOP

Simple use of the wave CHOP.

Modulus Major Scale

Use the power of modulus to convert any notes into a perfect Major Scale.

Beats

Generate triggers at perfect intervals for placement of music notes.

Chop Normals

Demonstrates how to blend normals with CHOPs.
