Reference Manual

387 Live Instrument Reference
The LFO tab contains two independent low-frequency oscillators (LFOs), which can each modu-
late multiple parameters. Similarly, the MIDI tab allows for MIDI pitch bend, modulation wheel
and aftertouch messages to be routed to multiple destinations.
To the right of the resonators is a section of global parameters, including overall output volume,
polyphony and resonator routing options.
In addition to serving as organizational aids, Collision’s tabs contain LEDs that light up to indi-
cate that their contained sections are active. Disabling unused sections can save CPU.
24.2.2 Excitator Tab
The Excitator tab contains parameters for the Mallet and Noise sections. These model the be-
havior of a mallet striking a surface, and provide Collision’s fundamental sound. These section’s
parameters only control the initial impulse, which is a much smaller component of Collision’s
overall sound than the resonators.
Note that if both the Mallet and Noise sections are turned off, Collision will not make sound.
The Mallet Section
Collision’s Mallet Section.
The Mallet section simulates the impact of a mallet against a surface. The parameters adjust the
physical properties of the mallet itself.
Volume controls the overall output level of the mallet section, while the Noise knob sets the
amount of impact noise that is included in each mallet strike. This is useful for simulating the
“chiff“ sound of a felt-wrapped mallet head. The Volume and Noise parameters can be modu-
lated by pitch and velocity by adjusting the K (Key) and V (Velocity) sliders, respectively.
