There should be a way to play the drums like a mpc

[LGofficial]

like, you set "drum a" to be played by a certain key, and "drum b", to be played by other key, so when you hit record, you can play them at the same time, cause its hella confusing to program your kick and the snare separatedly, and i always get it wrong

The native sampler in Reaper allows you to map different keys to samples. You can map an entire kit on one track or, as I do, set up multiple tracks with a different sample on each. It's pretty easy and free to try (for a good long time). You might want to record your loops in Reaper and then import the stems to LMMS???
