New user pattern question

[Friend of Dogs]

I think Islands of patterns may have been what I was looking for.

Is it that if there is a pattern made directly underneath the current pattern (thinking the sequencer screen), it will play them in succession? but if the (--) is there, it won't continue on?

I apologize, im trying to make sense.... its difficult


also while i'm here, i seem to be able to use midi to control only channel 4 so far. is that weird?

Hopefully these will be the only nooby questions I have, thank you for your help!
