No problem! I'm more than happy to help if I can with any questions you have :)
You don't NEED to use the Hyper Editor - you could simply record in the Arrange area of Logic in to the Piano roll, but using Hyper Editor will allow you to create a drum editor that looks more like a step sequencer.
I'd really recommend you check out Septembers edition of Steve H's Logic TNT1:
for full tips and tricks on using the Hyper Editor. Really well explained!
But, here is a basic outline of how to do this:
1. In the Piano Roll Create notes from C1 to C3.
2. Open the Hyper Editor.
3. In the Inspector Choose "Create Hyper Set for Current Events".
4. You now have a lane for each note, you rename each note - e.g. C1 becomes "Kick"
5. To use your MIDI Keyboard, simply make sure the SI track in the Arrange is selected (and record enabled) hit record in the Transport and play the notes.
5. You can adjust the grid and pen width and using the pencil tool draw in notes in the Hyper Editor.
6. You can also adjust velocity using the pencil or pointer tool when editing the drum pattern.
Hope that helps :)
