[. . . ] USER MANUAL 2 Information in this manual is subject to change without notice and does not represent a commitment on the part of Applied Acoustics Systems DVM Inc.

It is against the law to copy this software on any medium except as specifically allowed in the license agreement. [. . . ] The module has one output, the sound produced by the string, and three inputs. The first input signal is the bow velocity in the direction of the motion. The second input signal is a force signal which is considered to act perpendicularly to the motion of the string. The default value of the following parameters is set during construction · Length: the length, in meters, of the string. · Frequency: fundamental frequency, in Hertz, of the string when there is no pitch modulation signal or when its value is equal to 0. Note that the fundamental frequency is independent of the length of the string. The software automatically calculates the physical parameters necessary to obtain the required fundamental frequency. The default value of this parameter is 261. 62 Hz which corresponds to the middle C (C3) of a piano keyboard. This setting is convenient when controlling a Bowed String module with a Keyboard module. · Decay: proportional to the decay time of the sound produced by the string. · Inharmonicity: detunes the partial, toward higher frequencies, with respect to the fundamental. This parameter varies between 0 and 1, where 0 represents a perfect string. · Number of Modes: number of modes used to simulate the object. As the number of modes is increased, the number of partials in the sound increases but also inevitably the calculation load. · Excitation point: x-coordinate, in meters, of bow interaction point from the extremity of the string. · Listening point: x-coordinate, in meters, of listening point from the extremity of the string. The excitation and listening points should be the same in order to obtain a proper functioning. Note: For more details on this module and especially the front panel controls, see the Bowed Multimode module. 6. 15 Breath Controller This module is used to receive signal from a MIDI breath controller (MIDI controller number 2). Its one output, the breath controller signal, lies between 0 and 1 depending on the blowing strength. This module has no front panel control. 78 Specifications for modules The default value of the following parameters is set during construction · MIDI channel: MIDI channel used by the breath controller. 6. 16 Comb The Comb filter enhances frequency components located at harmonic intervals. The frequency response of the filter is composed, as shown in Figure 29, of resonances around frequency components located at multiples of a fundamental frequency (hence its name). The effect of the filter is to color the sound with a change of apparent pitch.
