This module is a hit and miss. If you, like me, have problems with your grip - if your finger joints hurt easily - then this is NOT your favourite module. Stay away! The pots are very, very stiff and hard to turn. On the second day of use my ”wiggle thumb” hurt badly and is (hopefully not for long) disabled.
That aside, the sequencer works mostly as expected. But there are some issues. Some functions are only available when clocked internally. But then there are no means to syncronize - well, apart from using the gate out, but that does not always give you the desired result. Trig in is used to start and stop the sequence - when running in repeat or single mode. To clock the sequence from an external source, only the setting ”step” can be used. But in that mode there is no trig out at the end of the sequence, as stated in the manual.
The original module had the output selectable 3 or 10 volts, if I’m not mistaken. For some reason (beyond me) Behringer opted for a compromise: 5 volts. I think that was not the best choise. Five octaves in one turn of a tiny trim pot - well, good luck with that! And only five volts for opening a filter fully - or whatever you want to use the CV for - that may not be enough. Of course the first problem can be mitigated with an attenuater before the VCO or the quantizer. That’s how I have been running it. Until my thumb gave up…
