Valve discontinued the Steam Controller in 2019 and the entire weird-input community went into mourning. Two haptic trackpads, four grip paddles, gyro, and a single analog stick where two were expected. Plot twist: as a MIDI controller, the Steam Controller is genuinely one of the best things you can plug into a DAW. Two XY pads on one device.
- What it is: the Valve Steam Controller running as a MIDI device on Mac or Windows via Universal Controller MIDI.
- What you get: 2 haptic trackpads (XY each), 4 grip buttons, 1 analog stick, gyro, 4 face buttons, 2 analog triggers with click.
- What you don\'t get: support from Valve. The controller is discontinued and the wireless dongle is irreplaceable if it dies.
- Time: 7 minutes including trackpad calibration.
Why this controller for MIDI
Three reasons it punches massively above its weight. One: two trackpads. No other gamepad has two large multitouch surfaces. Map left trackpad to filter cutoff + resonance, right trackpad to delay time + feedback, and you\'ve got two Kaoss Pads strapped to your hands.
Two: trackpad haptics. Each trackpad has a Linear Resonant Actuator that can pulse at any frequency. The bridge can drive these from MIDI CCs back to the controller — so your DAW can give you tactile feedback in time with the kick. It\'s the closest thing to adaptive trigger feedback on a non-Sony controller.
Three: four grip buttons. Two paddles per hand under the grips. Map them to scene launches and you\'ll never have to lift a thumb from a trackpad mid-set.
Setup (USB + Bluetooth)
The Steam Controller has a proprietary 2.4 GHz radio that requires its dongle. There\'s no Bluetooth. Wired USB works as a fallback.
Wireless via dongle
Plug the bundled USB-A dongle into the laptop. Press the Steam button. Both LEDs flash. The controller pairs automatically — the bridge identifies it as Steam Controller within two seconds.
Wired via micro-USB
Plug a micro-USB cable into the controller and the laptop. macOS and Windows recognise it instantly as a HID gamepad. The bridge identifies it correctly — Steam Input is not required.
Close Steam first
If Steam is running, Steam Input grabs the controller and the bridge can\'t see it. Right-click the Steam tray icon and quit before launching the bridge.
Default mapping
The Steam Controller preset reflects its asymmetry. The single analog stick maps to one CC pair, and the two trackpads each get their own XY pad. The four grip paddles get high-priority note slots.
| Input | MIDI | Notes |
|---|---|---|
| A / B / X / Y | Notes 60 / 62 / 64 / 65 | Xbox-style order |
| LB / RB | Notes 67 / 69 | Bumpers |
| LT / RT (analog) | CC 1 / CC 2 | Analog range, pre-click |
| LT / RT (click) | Notes 70 / 71 | Click at bottom of throw |
| Left trackpad X / Y | CC 16 / CC 17 | Multitouch, haptic |
| Right trackpad X / Y | CC 18 / CC 19 | Multitouch, haptic |
| Trackpad click L / R | Notes 86 / 87 | Press into the pad |
| Analog stick X / Y | CC 3 / CC 4 | Single stick, left side |
| Grip buttons (4) | Notes 84-87 | Two per hand |
| Gyro pitch / yaw / roll | CC 20 / 21 / 22 | Calibrate flat first |
Quirks and fixes
- Steam Input conflicts. Steam grabs the controller if running. Quit Steam (not just close the window) before using the bridge.
- The dongle is irreplaceable. Valve doesn\'t make these anymore. If your dongle dies, you\'re wired-only. Spare dongles sell for $40+ on eBay — buy one while you can.
- Trackpads default to mouse mode. Without Steam Input, the trackpads emit raw XY coordinates rather than relative mouse deltas. The bridge handles this correctly — Steam Input simulation isn\'t needed.
- The single stick is on the left. Most MIDI presets assume two sticks. Plan around the single-stick layout when mapping XY pads.
- Battery life is variable. Steam Controllers use 2x AA batteries. Lithium AAs give ~80 hours, alkalines about 25. Use lithium for tour, nicad rechargeables for studio.
- Firmware updates are gone. Valve killed the firmware update server. The controller\'s shipped firmware is what you have forever.
Limitations vs DualSense
Asymmetric (one stick, not two), no support from manufacturer, dongle is a single point of failure. The grip paddles are loud — they click audibly, which can be picked up by a vocal mic on a quiet stage.
But two large multitouch trackpads, two haptic motors, and four grip paddles add up to more performance surface area than any other consumer controller. The DualSense touchpad is great, but it\'s one pad. The Steam Controller has two.
Wrap + CTA
The Steam Controller is the cult-favourite weird input device of the 2010s, and as a MIDI controller it\'s genuinely unmatched on the trackpad front. Two XY pads, haptic feedback, four grip paddles, gyro. If you\'ve got one in a drawer, get it out.
Universal Controller MIDI is $89 one-time for Pro, free tier for the basics. Plug in the dongle, close Steam, calibrate the pads, and start performing with the most expressive discontinued controller ever made.
