mc.stutter~
Description
The stutter~ object keeps a history of its signal input (left inlet). Upon receiving an int (left inlet), it copies that number of the most recently received samples to another playback buffer. This buffer may be cycled through by its phase, 0-1 (right inlet). On receiving a (left inlet) or a trigger signal (middle inlet), the last integer number of samples are copied to the playback buffer.
Arguments
max-buffer-length [int]
The maximum buffer length, in samples. This determines the memory size of the record buffer. Parts of the record buffer are copied to the playback buffer when the object is triggered.
initial-buffer-size [int]
The initial buffer size, in samples, to copy from the record to the playback buffer upon receiving a trigger.
trigger-polarity [int]
The polarity to use for accepting a trigger signal in the middle inlet. If the argument is greater than 0, stutter~ accepts a positive trigger; otherwise stutter~ accepts a negative trigger.
number-of-copied-samples [int]
The number of samples which are copied from the record buffer to the playback buffer each iteration of the perform loop (the signal vector size). A larger value will decrease the stutter~ object's memory requirements and increase the CPU requirements.
number-of-outputs [int]
An optional fifth argument allows you to specify multiple independent signal outputs the stutter~ object will use when playing back from the playback buffer. The default is 1, and the maximum is 30. The number of phase signal inputs to the stutter~ object is also determined by this argument.

Multichannel Group Attributes
chans [int]
The chans attribute sets the number of channels and instances in the MC wrapper object. If you want a fixed number of channels regardless of what is connected to the object, you could set chans via a typed-in argument, for example typing would create 100 instances of a cycle~ object inside the MC wrapper. If chans is 0, the wrapper object will auto-adapt to the number of channels in its input multichannel signals (using the maximum of all connected signals). For objects without connected multichannel signals, the chans attribute will need to have a non-zero value if you want more than one instance.
If chans is changed while the audio is on, the number of instances will not updated until audio is restarted. However, if chans is reduced while the audio is on, any extra channels will no longer process audio and will output a zero signal.
values [list]
The values attribute only applies to object creation time so it must be set via typed-in argument syntax. values sets the first (and only the first) initial argument for successive instances in the MC wrapper. For example, typing would assign an initial frequency to the cycle~ instances inside the wrapper. The first instance would be assigned a frequency of 50, the second a frequency of 60, the third 70, and the fourth 80. Note that values does not determine the actual instance count; this can be done using the chans attribute. If there are more instances than elements for the values attribute, those instances are instantiated with the default value.
If you want to set a default initial value for all instances, simply type it as an argument before any typed-in attributes. For example, modifying our example above: . In this example, the first four instances are set as before, but the next six are created with a frequency argument of 100.
To change instance values or attributes after the wrapper object has been created, use the , , or messages.
replicate [int]
When replicate is enabled, input single-channel or multichannel signals containing fewer channels than the number instances in the MC wrapper object are repeated to fill all input channels. For example, when replicate is enabled and you connect a two-channel multichannel signal to the input of an MC wrapper object with four instances, channel 1 of the input will be repeated to channel 3, and channel 2 of the input will be repeated to channel 4. If replicate were disabled, channels 3 and 4 of the input would be set to zero.
target [int]
The target attribute sets a voice index for targeting specific wrapper instances. Subsequent messages are directed to an individual instance instead of all instances. It is strongly recommended you use the more reliable message instead of the target attribute. The voice index of will override the current setting of target. When target is 0, incoming messages are sent to all instances. When target is -1, incoming messages do nothing.
usebusymap [int]
When usebusymap is enabled, the MC wrapper controls whether individual instances process audio using a busy map maintained by either an mc.noteallocator~ or mc.voiceallocator~ object. When a channel in the busy map is marked as "free" or "released" no audio processing occurs by any instance on the channel corresponding to the voice index. When usebusymap is disabled, instances in the MC wrapper process audio at all times. This will also be true if usebusymap is enabled and there is no local or named busy map available. (See the busymapname attribute for a description of local and named busy maps). For brevity the name @bz can also be used.
zero [int]
When the zero attribute is enabled, channels in the MC wrapper due to the use of a busy map output zero signals. To save a small amount of CPU at the risk of loud and unpleasant noises due to uncleared signal data, you can disable zero. In this case, disabled channels in the MC wrapper do nothing to their output channels. If usebusymap is disabled or there is no active local or named busy map available, the setting of the zero attribute has no effect.
Conveniently, when usebusymap is enabled in mc.mixdown~ object, disabled channels are not mixed to the output. When unused signals from wrapped objects with zero disabled feed into mc.mixdown~, they will be ignored, reducing the risk of unpleasantness getting past the mix output.
busymapname [symbol]
When the usebusymap attribute is enabled, an MC wrapper object uses the local busy map of any mc.voiceallocator~ or mc.noteallocator~ in the same patcher by default. To use a named global busy map instead, set the busymapname attribute to the desired name. For brevity the name @bzname can also be used.

signal
In middle inlet: Accepts a trigger signal, which can be specified to be positive or negative. When the signal changes polarity in the correct direction, samples recorded from the left inlet are copied to the playback buffer.
In right and successive inlets: A phase signal input in the range of 0-1 for each inlet controls the output speed of the playback buffer for that inlet. The number of phase inlets in a stutter~ object is set using the fifth argument; the default is a single inlet. Specifying multiple phase inlets allows you to specify multiple playback points in the sampled buffer.
