Hi Allan, welcome to the forums. Clear introduction. If you could post your question in the DJ Booth I’ll give you an elaborate answer there. Your thinking is clearly but a bit flawed here and there as a result of being new.
You came to the right place, lots of people with mountains of experience (not in the very least your moderators with over 50 years combined 😀 ) and also lots of people in your position or those who have just moved on to the next step in their DJ-ing.
Enjoy your time here!
