Axoloit II is nearing the end of development (unfortunately for now that means no more Axolotis in stock, since the last batch of the original is sold out). Apparently it’s more or less the same thing with the same price but way more RAM and about 4x the CPU power. Mine is pretty underutilized right now but when the new one comes out I think I’m going to grab one anyhow, and dedicate the original to being a USB-MIDI host and MIDI processing box, and start underutilizing the v2 for synthesis experiments instead.
One downside for OT users is no more onboard DIN MIDI. It’s still there but it’s on pin headers now (to make room for the bigger CPU) and you have to get an off-the-shelf third party breakout board (or design your own) to actually use it. On the up side, there’s some chtter on their forum (aklthough it likely won’t actually happen, but IIRC the person talking about it is the same one who developed this https://zrna.org/ so you never know) about oe of the long time users who is a hardware developer working on an FPAA daughterboard or something - which would potentially mean being able to create analog circuits on the fly inside the Axoloti patcher.
