Searching the forum I found the old firmware
I installed 2.1.0 and found the original feedback with the envelope, I find it more musical.
Instead, trying the 3.4, I fell in love with the 2bp filter of the second filter mode. here too I find them very musical.
p.s. It would be great in general to be able to invert the env depth on the filter
between the original factory firmware which I assume is 2.1.0 and 3.4 I have not had the opportunity to try other modes
but as I found on 3.4 some notes are skipped from the sequencer (I use GC of endorphins and akai force)
so for now I'm using 2.1.0 but with regret for not having the 2bp filter mode
the module is fantastic for live performances and I would like the most from it I await updates
and I ask if there are other secret modalities that I can experiment with
Thank you for all the work you do
