as title says, i downloaded and tested the software today.
asus b450 plus mobo, 2x Crucial Ballistix Tactical Tracer rgb (addressable), 2 regular non-addressable rgb strips connected to mobo, amd wraith non-addressable rgb cooler, synapse 3 with a cynosa v2 keyboard connected.
using the "normal" effects from synapse (solid colour, breathing, spectrum cycle, audio meter), rgb strips, ram and cooler make the effect as the keyboard but not syncing colour, except with audiometer which synced the pattern and colour, even after applying to any other chroma enabled devices (by using the button next to the drop down menu) only audiometer syncs colour.
any other animations leave the strips, cooler and ram with the last working alteration made, and the advanced effects render the aura "device" leaving all leds off.
as an elite:dangerous player, i use a app for synapse that gives game related animations and key marking with the lights and colours. (faded unneeded keys, red for attack keys, blue for defence keys, etc) -- https://github.com/poveden/EliteChroma
with this app enabled while playing the game, ram shows some animations, strips and cooler go dark and flash in what seems to be randomly, but i think it might have a actual sequence to it. makes me believe that your app is reading from one exclusive key or set of keys and tries to show what that/those key/s are showing.
also, by using this app, there is a small variation in colour depending of my location ingame (from a light blue when in space, to a light faint green when i am docked in a station). surprised how it works, even if limited, in this situation with an extra app, and doesnt work with the built razer software options.
despite the amount of rgb items in my case connected to aura, your app only shows 1 connection in synapse, but i see 4 dots in it. would be great if each dot represents a aura device (as my example, strips which are connected on the same hub, therefore same mobo connector, 2 dims ram, cooler, 4 devices) and we could somehow change values for each device individually, opening a bigger option also to the creator of the other app for elite:dangerous.
would this be achieved in future? in a fairly long future.......
regards.
