csampler : creates a popup menu to load a soundfile in a sampler


csampler(name='sampler', label='Audio', help='')


This menu allows the user to choose a soundfile for processing in the module. More than one csampler can be defined in a module. They will appear under the input label in the left side panel of the main window, in the order they have been defined. When the user chooses a sound using the interface, Cecilia will scan the whole folder for soundfiles. A submenu containing all soundfiles present in the folder will allow a quicker access to them later on. Loop points, pitch and amplitude parameters of the loaded soundfile can be controlled by the csampler window that drops when clicking the triangle just besides the name of the sound.

A sampler returns an audio variable containing Cecilia’s number of output channels regardless of the number of channels in the soundfile. A distribution algorithm is used to assign X number of channels to Y number of outputs.

In the processing class, use the BaseModule’s method addSampler to retrieve the audio variable containing all channels of the looped sound.

BaseModule.addSampler(name, pitch, amp)

For a csampler created with name=’mysound’, the audio variable is retrieved using a call like this one:

self.snd = self.addSampler('mysound')

Audio LFOs on pitch and amplitude of the looped sound can be passed directly to the addSampler method:

self.pitlf = Sine(freq=.1, mul=.25, add=1)
self.amplf = Sine(freq=.15, mul=.5, add=.5)
self.snd = self.addSampler('mysound', self.pitlf, self.amplf)


name: str

A string passed to the parameter name of the BaseModule.addSampler method. This method returns a Mix object containing Cecilia’s number of channels as audio streams from a Looper object controlled with the sampler window of the interface.

label: str

Label shown in the interface.

help: str

Help string shown in the sampler popup’s tooltip.
