#X text 42 20 You can use [send~]/[receive~] for feedback loops. Feedback loops are also useful in delay lines as shown in some of the examples in the 'G' series of the audio examples. Feedback loops with delay lines are useful when you need to change the delay size \, but sometimes you want a fixed delay time.;
#X text 54 428 Note that feedback loops usually requites a single connection \, in this case you can also use [throw~]/[catch~]. Hence \, the decision to focus on [send~]/[receive~] instead is a bit arbitrary., f 62;

#X text 42 105 The delay time for [send~]/[receive~] is fixed at one block and you can use it as the desired fixed delay time. You can change the block size for a patch window with the [block~] object \, the default block size is 64 but common examples are a single sample feedback loop (block size of 1 for things like filter design and more) or FFT processing with block sizes that are much larger (like 1024 or 2048).;

#X text 37 88 A [send~] object copies its input to a local buffer which all [receive~] objects of the same name read from. They may be in different windows or even different patches. Any number of [receive~] may be associated with one [send~] \, but it is an error to have two [send~] objects of the same name. A [receive~] takes "set" messages to switch between different [send~] objects. Multi channel connections is supported., f 72;
