Fairly new here and I thought I'd ask for some advice; I'm a percussionist and was delighted to find that they included a marimba (it's not a xylophone) as one of the instruments you can work with, but I'm torn between practicing with that and the piano since the latter is used for all of my aural theory tests for uni. I've been trying to split my time between the two but whenever I switch I notice a slight drop in my ability due to the different timbres and I usually have to go back a couple levels to relearn things with both instruments. Should I continue this way or just pick one?
