New to hardware, I want to upgrade from my volca sample 2

Hey there, I’ve got a pretty bare bone set up right now. I’m rocking a Behringer TD 3MO, a Yamaha reface CS, and a volca sample 2. I like the sample, but I really want to be able to import longer samples and I hate how you have to transfer the audio through the sync input. I really mostly use it like a drum machine I like the immediacy to it, and I am a big fan of the motion sequencing. I was thinking about replacing it with an SP404 (vocal fx, sd card, and beefy sampling) or a P6 (compact), or maybe even the circuit tracks.

To give you an idea on the sound that I like, I’m a big fan of look Mum no computer, i’ve been getting into acid. So if you guys have any thoughts on a good sampler sequencer please let me know. FYI, we’re topping out at my absolute maximum being $500 and that is pushing it really hard with my budget.

Any response is appreciated, thank you for reading this!

TLDR volca sample upgrades for under $500?
