Just curious - are you able to create your own sounds to sample/fill yours with other stuff?
I understand keeping the stock stuff around to learn from, it's nice to see some sort of foundation (even though the sounds are always janky!), but samplers really need your personal sounds in 'em to fully start making sense. I was so lost on my first one but once I deleted all the stock stuff off and put even just one or two kicks/snares/hats and a few other elements I personally dug on it, HOLY CRAP, everything started to click.
Strange how samplers really work like that but they truly are 'organic boxes'! Ha
If you decide to take the plunge, don't think twice!
Peace
