Also for the OP here’s a tip of my own: Explore making whole compositions with just the A4. Have one track be for a melodic line (or you can use the chord tip above for a four-note progression, and use track scale to extend that beyond four bars) and the other three tracks just for percussive sounds. Put your favorite drum patches in the sound pool and p-lock different ones on various step per track, plus send amounts to delay and reverb to make sounds on the same track appear to overlap. Try using different track lengths and probability on some steps to make the drum pattern ever-changing. Then go into performance mode and set the knob destinations to useful and performative parameters on all four tracks. Lastly use the FX track and sequence/modulate some parameters there as well.
Forcing yourself to use only the A4 as an exercise makes you realize how far it can be pushed. As a “drum machine” I consider it to be superior to all other Elektrons, and indeed one of the best in the world.
