Hardware-level key hold (W down while key is held) with Synapse or multiple keyboards

Hello,

I play Knight Online and I'm looking for a hardware-level input solution, not a software-based one.

My current setup:

I use a Bloody keyboard for skill macros.
For example, when I press the 3 key, the keyboard continuously casts the skill in a 3R 3R 3R pattern.
This part works flawlessly and I don't want to change it. What I want to add:

I want to use another keyboard feature or a second device (e.g., a Razer keyboard) to control movement simultaneously.

Desired behavior (very clear):

When I HOLD DOWN the 3 key:
The keyboard should send the W key as DOWN (pressed) and keep it pressed continuously.
While W is pressed, my Bloody keyboard should continue sending 3R 3R 3R.
In other words, the move (W) and skill (3R spam) should work simultaneously and smoothly.
When I RELEASE the 3 key:
The keyboard should immediately make the W key UP (released).
The move should stop immediately.
Critical requirements:

W must be genuinely held down, not press-and-release/spam.
There should be no delay, no W up/down flickering.
The solution must work at the hardware/USB HID level.
Software like AutoHotkey doesn't work in this game.
I've tried everything with the Bloody keyboard but couldn't solve it.
My questions:

Can Razer keyboards (Synapse 3) do this? Specifically: Example: When I hold down the 3 key, the keyboard should cast the 3R3r skill while the W key is also held down.
Does Razer support real key-down/key-up macros at the hardware level, without loops? NOTE: I tried AutoHotkey but couldn't find a solution. The game algorithm doesn't recognize the W key as held down.
Thanks.
