No love for this teeny box?

Just made an accidental but nice sounding patch

I got one of these as a gift for the holidays. I wasn’t sure what I’d do with it, or how useful it would be in actually making songs, but it’s kind of a blast what you can do with this thing. It also pairs really well with ambient reverb, like the Walrus Sloër.

Anyway, for the price point, it’s pretty hard to beat as a little piece of inspiration.

Hello guys, what kind of instrument is the Bastl Kastle Drum? I wouldn’t call it a “drum machine”, it just produces synthdrum sequences, I’d need this info to search for a Kastle Drum substitute as I’d like to explore more of this.
Same thing for the ARP, how would you call it? Is there something similar?

I DO NOT have a modular system but if the only options are modular I may check them out and buy a small case, maybe 🥹

liquid glitcher sounds very close and also creates drum synth sequences
