Reply to V3.6.4 mapping question

hi there folks,

maybe its been discussed here previously, but i found nothing by search.

so i imported the latest V3.6.4 mapping and experience some issues. for example whenever i press the shift button i hear annoying clips and pops. also when i want to insert hot queues and press shift and tap on jog wheel it slows down the deck. there are possibly other issues by i haven't looked up other functions further.

i'm believeing that it must be the firmware, but i don't know which one i have. i know it has a green circle sticker near the serial number. so how do i determine which fw version i have, and if its too old do i mandatory have to buy the fw upgrade kit, or is there a workaround?

sorry for noob questions, thanks for being supportive - i know you always are
