well if you want to have simultaneous outputs you need to set the redstoneDelay in the settings.conf to 0 (or less than a tick < 0.05) there is currently no other way to achieve that.
But be aware if you do so, you need to build a custom timing system into your script to avoid double calls on redstone in one tick otherwise you could end up with really bad MC performance.
I use something like this:
local redstone = require("component").redstone --lazy shorthand for demo purpose dont use that until you know why
local tick = computer.uptime() --get the current ingame uptime in se
