File

Selects a pre-recorded sound file to be used as the granulation source. Click on the Select Sound File button to choose a file. Alternatively, drag a sound file into the contraption's sound file slot directly from the Macintosh Finder or Windows Explorer. The name and source of the file will be displayed in the sound file slot.

Amp

(Amplitude)

Specifies the range of possible amplitude values available for each grain.

Pan

(Panning)

Specifies the range of possible stereo panning locations available for each grain.

Inskip

Specifies the range of possible sample inskips available for each grain. Each grain uses a separately selected segment of the specified file.

Trans

(PitchScaler)

Specifies the range of possible transposition factors available for each grain. The range is +/- 2400 cents (+/- two octaves) from the original pitch. Positive transposition factors shift the output higher in pitch. Negative factors lower the pitch. Trans affects the rate (speed) at which each grain is played back.

Densi

(Density)

Specifies the average density of grains, expressed in number of grains per second.

Quant

(QuantizeAmount)

When the clock is running, BubbleBlower allows the onset times of all grains to be quantized. Set the amount of quantization from none (0%) to total (100%). The clock must be running for Quant to work.

Q. Period

(QuantizePeriodMultiplier)

The Quantize Period settings below the Quant slider lets you specify the quantization period (spacing of quantization pulses) as a rhythmic unit multiplied by a number.The clock must be running for grain quantization to work.

Gdur

(GrainDuration)

Specifies the range of possible durations available for each grain. The available range is 5 - 500 milliseconds.

Shape

(AttDecRatio)

Each grain has an amplitude envelope consisting of an attack, sustain and decay portion. Shape determines the duration of the sustain portion relative to the duration of the attack and decay portions. When shape is 0, the envelope is a triangle, when it approaches 1, the attack and decay portions shorten and the envelope becomes more rectangular.

Skew

(GrainSkew)

Specifies the range of possible envelope skew factors available for each grain. Skew adjusts the relative duration of the attack and decay portions of the grain envelope. Smaller values of skew decrease the attack time and increase the decay time. Larger values of skew decrease the decay time and increase the attack time.

Max Grains

(MaxGrains)

Controls the maximum number of simultaneously overlapping grains, ranging from 1-200. Due to the limited processing power of computers, you cannot mix an infinite number of overlapping grains in real time. Even the maximum number of grains in BubbleBlower (200), can be too hard for slower computers to mix. Avoid audio glitches on slower computers by lowering the Max Grains setting. Lower Max Grains settings will, however, result in a thinner texture.

DCor

(Decorrelation)

Controls the level of correlation/decorrelation between randomized grain parameters. When set to 0, parameters for a single grain are correlated so that, for example, higher pitched grains are panned to the right. When set to 1, the relationship between grain parameters is decorrelated, or completely random.
