oscbank~
Description
oscbank~ is a non-interpolating oscillator bank with signal inputs to set oscillator frequency and magnitude.
Examples

oscbank~ creates a bank of oscillators that you can control with one object
Arguments
number-of-oscillators [int]
Optional
The number of oscillators.
frequency-smoothing-factor (samples) [int]
Optional
The number of samples across which frequency smoothing is done.
amplitude-smoothing-factor (samples) [int]
Optional
The number of samples across which amplitude smoothing is done.
lookup-table-size (samples) [int]
Optional
The size, in samples, of the sinewave lookup table used by the oscbank~ object. The default is 4096. Since oscbank~ uses uninterpolated oscillators, you can choose to use a sinetable of larger size at the expense of CPU.
Note: There is only one wavetable for all oscillators in a given oscbank~ object,

Messages
int
Arguments
inlet-specific-parameter-settings
[int]
Performs the same function as
in any inlet (see and messages). float
Arguments
inlet-specific-parameter-settings
[float]
In left inlet: Sets the frequency of the oscillator whose index is currently referenced to the current floating-point value of the signal. The default value is 0.
In 2nd inlet: Sets the magnitude (amplitude) of the oscillator whose index is currently referenced.
In 3rd inlet: If is enabled using the message, a value in the range 0-1.0 sets the phase of the oscillator currently being referenced.
In 4th inlet: Sets the index of the oscillator currently being referenced.
In 2nd inlet: Sets the magnitude (amplitude) of the oscillator whose index is currently referenced.
In 3rd inlet: If is enabled using the message, a value in the range 0-1.0 sets the phase of the oscillator currently being referenced.
In 4th inlet: Sets the index of the oscillator currently being referenced.
clear
The word
sets the frequency of all oscillators to zero and zeros all amplitudes. copybuf
Arguments
buffer-object-name
[symbol]
offset (samples) [int]
offset (samples) [int]
In left inlet: The word oscbank~ object's internal wavetable. The number of samples is set using the message. An optional second integer argument specifies the position in the buffer at which samples are loaded (offset).
, followed by a symbol that specifies a buffer, copies samples from the buffer into the framesync
Arguments
behavioral-flag (0 or nonzero)
[int]
The word
, followed by a non-zero number, enables frame synchronous operation. When frame synchronous operation is enabled, a given index's values will only change or begin their interpolated ramps to the next value when the index input signal is 0 (or once per n sample frame). Otherwise, a given index's values will change or begin their interpolated ramps to the next value when the index input signal is equal to that index. The default is off. freqsmooth
Arguments
frequency-smoothing-factor (samples)
[int]
The word
, followed by an , sets the number of samples across which frequency smoothing is done. The default is (no smoothing). magsmooth
Arguments
amplitude-smoothing-factor (samples)
[int]
The word
, followed by an , sets the number of samples across which magnitude (amplitude) smoothing is done on a oscillator. The default is (no amplitude smoothing). set
Arguments
frequency-amplitude-pairs (floats)
[list]
The word oscbank~ object and zero the amplitude of all others.
, followed by pairs of floating-point values, sets the frequency and amplitude of an oscillator in the oscillator bank. A list of n pairs will set the first n oscillators in the signal
In left inlet: Sets the frequency of the oscillator whose index is currently referenced to the current floating-point value of the signal. The default value is 0.
In 2nd inlet: Sets the magnitude (amplitude) of the oscillator whose index is currently referenced.
In 3rd inlet: If is enabled using the message, a signal in the range 0-1.0 sets the phase of the oscillator currently being referenced.
In 4th inlet: Sets the index of the oscillator currently being referenced.
In 2nd inlet: Sets the magnitude (amplitude) of the oscillator whose index is currently referenced.
In 3rd inlet: If is enabled using the message, a signal in the range 0-1.0 sets the phase of the oscillator currently being referenced.
In 4th inlet: Sets the index of the oscillator currently being referenced.
silence
The word
zeros the amplitude of all the oscillators. size
Arguments
number-of-oscillators
[int]
The word
, followed by a number, sets the number of oscillators. The default is 64. The maximum number of oscillators is set by the argument first argument to the object. tabpoints
Arguments
lookup-table-size (samples)
[int]
The word oscbank~ object's internal wavetable. The default is 4096. The number of wavetable points should be a power or two between 2 and 2 16 . Any other value will be rounded to the nearest power of two.
, followed by a number, sets the number of wavetable points (samples) in the Output
signal
A waveform consisting of the sum of the specified frequencies and amplitudes.
