MCP4SH™ · String Theory Haptics for SimHub
High-level plugin overview
Haptics that aim to feel more like a connected chassis and less like a pile of buzzing.
MCP4SH™ is a SimHub plugin built to make sim-racing haptics clearer, more readable, and more useful. The goal is not just more shake. The goal is better cues: tyre scrub you can read, road and suspension detail that feels separated, drivetrain information that makes sense, and less time wasted re-tuning everything from (almost) scratch every time you switch sim.

What it does
Cleaner cues
MCP4SH tries to make grip, scrub, suspension, road texture, drivetrain, and weight-transfer style cues easier to separate and interpret.
What it avoids
Less chaos
The goal is to reduce noise in the vibration signals so the feedback feels more coherent and, more like a car.
Why it matters
More usable feel
A good haptics layer should help you trust what you are feeling faster, with less second-guessing and less endless profile babysitting. Helps you drive intuitively.
Licensing and roadmap
Base plugin first. Paid adaptive layer on top.
The base plugin is there to be usable and honest on its own. The paid side is about the premium adaptive layer and about supporting the work that keeps the project moving.
Current early-adopter option: Pioneer — 12.99 for up to 2 machines.
(early adopter bonus)Planned standard option: Supporter — 12.99 for 1 machine.
Planned later, if demand justifies it: Pro — likely 19.99 with a higher machine allowance.
The store listing is the source of truth for what is live right now. If the roadmap changes, the store and GitHub release notes will reflect that.
What paid adds
Why there is a paid version
- ST Tensioner: helps the important effects push through when they matter, instead of everything fighting for attention at once.
- ST Balancer: helps keep the overall feel more composed across different titles.
- ST Learner: the premium side is where the more adaptive, per-session dynamic behaviour lives.
- Future support: paid licenses directly support refinement, compatibility work, and ongoing development.
FAQ
Here's the thing
But, what does it actually do?
It is a SimHub ShakeIt Bass Shakers haptics plugin that tries to make feedback feel more like a car than a pile of vibrations. The goal is to better separate tyre, scrub, road, suspension, drivetrain, and weight-transfer style cues so the rig feels more informative and less chaotic.
Is this just “more vibration”?
No. That is the opposite of the point. MCP4SH is meant to reduce the sense of random buzzing and make the overall signal easier to trust. More output is not automatically better output.
Why is there a paid version?
Because the project has a usable base layer and a more advanced adaptive layer. The paid side unlocks the premium ST systems and helps fund the time, testing, and refinement needed to keep improving compatibility and behaviour across sims and hardware setups.
What does the paid version add?
The paid side adds the premium adaptive layer, including ST Tensioner, ST Balancer, and ST Learner. Put simply: more control over what pushes through, better overall composure, and the more advanced side of the system that sits above the already-usable base plugin.
Do I need to spend ages tuning it per game?
Nope, pretty much works out of the box. That said, rigs, transducer layouts, amps, and personal taste obviously still matter.
Does it work the same in every sim?
Mostly, yes. No haptics solution works identically across every sim because telemetry quality and behaviour differ. MCP4SH is built to be broadly usable across common driving titles, but some sims will always give cleaner raw input than others.
Why are there not more videos yet?
Because haptics are awkward to show well, and the project reached a releasable state before the showcase material was finished. Workin' on it.
A quick honesty check
Sanity/Reality check
This is not magic, instant pace, or one-click perfection (almost, but not quite). It is however a serious attempt to make haptics more coherent and useful, and plug and play (ish). Your rig, transducer layout, amp chain, gain staging, and sims still matter. The goal is to start from a stronger place and give you something more readable to work with. It removes complexity in tuning without losing fidelity.
