This is for a Synthrotek Adsr. This module has both looping/lfo capabilities along with the usual Adsr capabilities.

When in Adsr mode the module functions as normal. When in AR mode this module goes into looping lfo mode.

This module has an issue with the AR (looping envelope) mode. It will not start looping until it receives a signal-but once it does it works as intended.

Other than that the unit works perfectly (and quite snappy)!
