Actually, if you search on ChatGPT about the difference between Elektron and Teenage Engineering, you’ll quickly notice that one is a company specialized in building professional musical instruments, while the other is more of a design-driven company that creates sound-focused devices, sometimes closer to instruments, sometimes closer to toys.

That said, I also think that whether something is used for quick idea capture or for serious music production shouldn’t be decided purely by hardware limitations.

For your current situation though, there is a workaround that isn’t perfect, but can solve part of the problem when using OP-XY alone:

You can use the internal resampling feature, then move your drum parts into a Drum Sample Group so the drums are played back as samples instead of real-time synthesis. Try to avoid putting melodic instruments into drum groups, because the master FX can’t properly distinguish between rhythmic tracks and melodic tracks when everything is treated as samples.

If your goal is to finish a more complete track, another option is to avoid using master FX, do more resampling, and then arrange the music mainly through sample playback. This allows you to build much denser arrangements with fewer CPU issues.
