Examples
oscbank~ creates a bank of oscillators that you can control with one object
Non-interpolating oscillator bank
| Name | Type | Opt | Description |
|---|---|---|---|
| number-of-oscillators | int | opt | The number of oscillators. |
| frequency-smoothing-factor (samples) | int | opt | The number of samples across which frequency smoothing is done. |
| amplitude-smoothing-factor (samples) | int | opt | The number of samples across which amplitude smoothing is done. |
| lookup-table-size (samples) | int | opt | 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, |
| int | inlet-specific-parameter-settings [int] |
Performs the same function as in any inlet (see and messages). |
| float | oscillator-phase (0.0 through 1.0) [float] |
Performs the same function as a according to each inlet. |
| clear | The word sets the frequency of all oscillators to zero and zeros all amplitudes. | |
| copybuf |
buffer-object-name [symbol] offset (samples) [int] |
In left inlet: The word , followed by a symbol that specifies a buffer, copies samples from the buffer into the 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). |
| framesync | 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 | 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 | 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 | frequency-amplitude-pairs (floats) [list] |
The word , 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 oscbank~ object and zero the amplitude of all others. |
| silence | The word zeros the amplitude of all the oscillators. | |
| size | number-of-oscillators [int] |
The word , followed by a number, sets the number of oscillators. The default is 64. |
| tabpoints | lookup-table-size (samples) [int] |
The word , followed by a number, sets the number of wavetable points (samples) in the oscbank~ object's internal wavetable. The default is 4096. The number of wavetable points should be a power or two between 2 2 and 2 16 . Any other value will be rounded to the nearest power of two. |
| 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. |
