first thoughts:
the most exciting bit for me is i2c. after scanning the manual it looks like faderbank (in leader mode) is the primary use case. this means it responds to the er-301 “set CV” command - so in theory you should be able to use it with teletype immediately by using SC.CV op. and indeed, the default i2c address (which can be set to any address) is the er-301 address.
since it’s configurable, you should be able to change it to one of the telexo addresses too and use TO.CV op instead, if you already have er-301 (or use a different TXo address if you already have 1-3 TXos on the bus).
looks like right now you can only use i2c to control algo parameters - i hope os considers adding the ability to also use i2c to load presets and switch algos. this also means you can’t use it as a i2c-select bus converter at the moment.
still, pretty exciting to have processing / sampler unit with i2c control! just wish it wasn’t 50mm deep…
it also displays i2c history - combined with fully configurable address this could be a great tool for developers who need to debug i2c related stuff.
