I just created this section to post useful PureData patches. I am using OSC a lot these days, so many will be related to that.
prependaddr
This is useful for prepending part of an OSC address onto the first item of a list. (Converts it to a string if it is a number.)
For example, clicking the left-most message here will output ”/test/me 1 2 seven”. The “set” message can be used to change what is prepended, or equally whatever is received in the second inlet. The patch uses only vanilla Pd objects.
