I managed to snag a Roland SH-01 Gaia in incredible condition — like new — for **SEK 2,500** , which is roughly **US $262** at current exchange rates.

The checksum function in the Electra One SysEx editor is absolutely brilliant. I’m currently working on an editor for the Gaia, and since this is the first time I’ve ever used a checksum in Electra One, having this feature built in has been incredibly helpful. It takes all the guesswork out of creating reliable SysEx messages and ensures that every string is accurate and safe to send. Instead of manually calculating or double-checking values, the editor handles it instantly and flawlessly. It speeds up the workflow, boosts confidence, and quietly does a lot of heavy lifting—simple, dependable, and invaluable.
