Modulation System

Modulation brings the sounds in Iris to life, giving them movement and expression that

wasn’t available in Iris 1. With Iris 2 we created an extensive modulation system that is

intended to give users the ﬂexibility and connectivity of a modular synth. Iris 2 has four types

of Modulation Sources: LFOs, Envelopes, MIDI Expression Controllers, and Macro Knobs.

These Modulation Sources can be connected to over 100 modulatable parameters in Iris 2.

MODULATING KNOBS AND SLIDERS

Any knob or slider that has three small circles next to it is a Modulatable Knob or Slider.

These small circles are called Modulation Inputs. These Modulatable Knobs and Sliders

accept up to three modulation sources represented by the three small circles. Applying a

Modulation Source to a knob or slider brings that knob or slider to life, giving it movement

and expression. For example, a Low Frequency Oscillator (LFO) will continuously change

the value of the knob or slider as you play notes. A modulation source such as Velocity will

change the value of the knob depending on how hard you hit a MIDI key. After a Modulation

Source has been connected to a Modulation Input, the circle turns into a small knob which

allows you to adjust the modulation range.
