Hello,
Yes, if you’d like more control beyond the 1-button looper, it is best to use a 3-button aux switch or MIDI controller.
If you’d like some tips or advice about using the 1-button looper, I am happy to offer some help.
A user has posted a great looper tutorial here: https://www.thegearpage.net/board/index.php?threads/looping-with-the-h90-part-1-basic-setup.2478513/
