I am an absolute beginner with Midi CC. I looked into the midi implementation and found "7.39.5 Step Sequencer Pattern Number Select. This was very confusing for me and seems incomplete. So i downloaded the free App Midi Wrench for Ipad. The app shows me the Midi CCs when i press a button on my Synth. :-) I do Midi Recording with my DAW on my PC. But I want to record Midi without the PC or Ipad, too. So when i am practising with my synth and i have a spontaneous idea, i want to record it immediately without booting my PC. :-) By the way. I have a tascam 4 Track, too. Its a Tascam 424. I used it in the mid 90s for recording a complete Band: 2 Guitars, 1 Bass Guitar and Drums on 2 Tracks, on the other 2 Tracks Vocals. That was very hard to mix. I am glad that i dont need it anymore, now its in the basement. :-)
