hey, im new here.

wanting to know if its possible to use bomes mouse keyboard / redrum to create drum patterns?

You can make drum patterns by using the mouse on Redrum's step sequencer. That's the only way to make a pattern.

You could use the virtual keyboard to record a note sequence in the sequencer, which would do the same thing and trigger samples in redrum channels. But it's totally unneccesary; if you want there to be notes in the sequencer for the redrum, you can just use the step sequencer then right click on redrum and select "copy pattern to track" (or something along those lines).
