I often play a long sequence of drums or synths 30 seconds or more and not hassle around setting up patterns because you can be in the moment with these things placing the entire skeleton of your work before you go back to flesh it out immediately after or later. Almost to the "back of the hand Bob Ross painting on the fly" level with sequencing with this technique.
To do this, simply switch from pattern mode to song mode and then go into the sequencer after you have selected a machine. Tap the grid icon on the top left corner of the screen next to the label "Patterns" to enter piano roll mode. Look for the magnifying glass icon with the music notation note icon next to it. Tap or click the notation note to reveal a "Q. Tize" icon on the right side. Click that to disable quantization then click the notation note to exit back to editing mode. Go back to your machine you want to record and arm your metronome to precount by selecting the count in measures feature after you have clicked and held (or pressed and held) on the metronome icon. Now you can record your sequences in full. If you want, immediately tap the metronome again to record without the sound of the metronome before the count down ends.
To edit, go back to the sequencer and enter piano roll mode. Click or tap the piano roll label then select your machine. If you feel up to it you can also insert patterns too, it doesn't effect your piano roll song sequences, at least not yet.
Now go Bob Ross the shit out of your projects and tell Fuller to go easy on the Pepsi.
