triangles

endless triangles

Each of the four voices consists of 2 triangle waves and some noise. Each voice is independently triggered by its own (tempo-sync’d) clock source. Adjust the amplitude envelope, filter cutoff, vibrato and bit rate of each voice to taste.

Requirements

• norns
• MIDI controller (optional but recommended)

Documentation

• K2: randomise parameters

Use the norns parameter menu PARAMETERS > TRIANGLES to change the parameters of each voice. Most parameters should be self-explanatory but there’s a few less obvious ones:

• detune detunes one oscillator against the other in the voice
• bellow alters the mix between the two oscillators on the rise and fall of the envelope. 0.5 (default) plays both oscillators equally throughout the envelope, while 0 plays oscillator 1 on the rise, and 2 on the fall. 1 reverses this.
• curve adjusts the curvature of the perc amplitude envelope
• trigger frequency how often (in beats at the current system clock tempo) the envelope is triggered.
