I have the same problem/question/request. There seems to be no shortcut on the Keylab61 mk2. I agree, reaching for my mouse when I am sorting presets, when the sampling and forward and back buttons are available on the controller, is annoying and prevents an efficient rhythm to this long process. i would love to assign a button to "like" but there seems to be no way to do assign that in Analog Lab V even if i wanted to assign custom controls for that software. The Midi Control Center doesn't list that as an optional key command to assign manually before opening Analog Lab V. I have no idea what your other two replies are talking about. If you figured this out, please let me know. I will request that for the next update release. please help me gang up on them. This should be a simple fix. technical.support@arturia.com
