I decided to keep the SH-4D, mostly for drum/percussion sounds.

I've ripped out all the percussion tracks from most of my music of the past few years after hearing that Splice allegedly doesn't vet their samples properly, and confirming that their terms of service include a "use at your own risk" clause to avoid any responsibility on their end.

I do have other trustworthy sources of samples, but redoing so much is a daunting task and I wanted something portable and fun to help me get through it. The SH-4D's interface isn't my favorite, but it's got a good amount of hands-on tweakability and I honestly can't find a better drum machine for the price, even if that's not its primary purpose. I'm sure I'll make use of the synth parts too eventually.
