to become continuous. This parameter can be used to produce interesting effects by exciting the
resonators randomly. This parameter can be modulated with the the pitch or velocity signal from
the keyboard or with the output from the Noise Envelope or LFO module.
The Direct slider linking the Mallet and Noise modules is used to mix signal from the Mallet
and Noise sources with the signal from the resonators in the final sound of the instrument. When
the slider is set in its bottom position, the output fed to the output stage only contains the sound
from the resonators, in other words the source is filtered by the resonator. Increasing the level of
this slider increases the amount of source signal added to the signal from the resonators.
4.5 The Resonator Module
The Resonator modules represents physical objects used as acoustic resonators.
The Resonator selector allows one to choose the type of resonator used. The resonator type
can be changed by clicking on the resonator icons or by using the drop-down menu at the top of
the module. Available types are:
• String: a perfectly elastic string,
• Beam: a rectangular beam with constant cross-section,
• Marimba: a beam with variable section allowing one to obtain partials having a quasi-
harmonic ratio,
• Plate: a rectangular plate,
• Membrane: acoustic membrane as in a drumhead,
• Open Tube: a cylindrical tube with both ends open allowing one to obtain the complete
harmonic series (even and odd harmonics),
• Closed Tube: a cylindrical tube with one end closed allowing one to obtain only odd har-
monics,
