it's strange, both the front button and double pressing the preset page button should act exactly the same in terms of confirmation but yeah, when i tried it yesterday it seems there is no confirmation when using the front button. i'm working on the next minor release for orca and will look into fixing this (maybe just increasing how long the notification is displayed for).
one difference between the 2 methods is that both store to flash but only the front button will also store to a USB stick. i've updated the manual to reflect that.
so, one thing that i'm considering changing is being able to store individual banks/presets. right now it stores all 8 banks and 8 presets, so if you changed one preset, switched to another one, changed the 2nd one and then saved it will save the changes for the first preset as well. the pro is that if you forgot to save the first one it will still get saved. the con is that you might actually not want that... especially if you use the rotate/mutate sequencers, you might not want to store the changes introduced by them. in this case i suggested creating a preset, then copying it to another one and using that one for any mutations / live changes, so that your main sequence always stays intact. alternatively, you can reload a preset from flash to abandon the changes before you save.
thoughts? is it more convenient to be able to store individual presets / banks? i guess it could do both with different presses, either store all presets or individual ones. and what button combo should be used for individual save? i wish i didn't use the same gesture (double press) for reloading a preset (when you double press a preset) and saving all presets (double pressing the preset page button), but at this point i also don't want to change it to something completely different as it would add to confusion. perhaps it could work this way: double pressing a preset still reloads it from flash, double pressing the preset page button stores the currently selected preset, and pressing and holding the front button stores all presets?
re: initial presets - no special meaning, when orca is started for the first time it randomly selects values for the track divisors and phases, as well as track selection for CV A and B from one of the arc presets, the rest is just a default state (0 for resets and chance, no rotate/mutate sequencers, trigger outputs follow their respective tracks, track weights are set to 1, 2, 4, 8). and then it saves it right away to flash, so next time you turn it on it will still have these initially randomly selected presets.
