My hunch is that kria is too complex to recreate with grid ops. If you’re up for some lower level programming, maybe it could be done with multipass?
Sort of - but teletype couldn’t talk to grid in the same way as if it were directly connected by USB. If you have the latest firmwares, you can simulate grid button presses via teletype ops. Most of teletype’s ansible commands are targeted at controlling the apps themselves rather than the grid directly.
It might be noteworthy that you can hot swap grid on both ansible and teletype, and they’ll continue what they were doing. E.g. if you set up a sequence on ansible, then move grid to teletype, ansible keeps on playing that sequence with the grid disconnected, and you can still control ansible using teletype ops. If you reconnect the grid, you pick up where you left off and can continue modifying the ansible parameters.
I can’t speak authoritatively on that. I have ER-301, Ansible, teletype, crow, TXo, TXi, and faderbank all on one i2c bus. They’re all in the same case (Intellijel 7u) along with a bunch of other things and I haven’t needed extra power. However grid is powered externally by two>one from another case, and faderbank is externally powered as well.
