howto build an effect for mx

since mx version 0.6 effects (delay, reverb) and inserts (compressor, limiter) are built as abstractions in order to create multiple instances. a motherpatch is used to netload one or more effect. effects and inserts are treated the same. it is possible to use a chorus as insert or a compressor as effect, without any sense.

the motherpatch:
- includes an abslist with its effect(s)
- add the effect(s) to mx's fx-list so we can use it.

please check the example-lib:
( example-lib.pd , vol.pd )
