What’s New in MIDI Uno 1×1 Software v2.6.4 (November 2025)
Released on November 12, 2025, the latest MIDI Uno 1×1 software brings meaningful upgrades:
- Native Windows 11 24H2 and Arm64 support (finally no more compatibility warnings)
- ASIO4ALL-free ultra-low latency mode (2.1 ms round-trip at 48 kHz confirmed on Ryzen 7000/Intel 14th gen)
- Built-in MIDI router and filter panel (no need for third-party tools like MIDI-OX)
- Dark mode interface + redesigned LED activity monitor
- Automatic firmware updater (current firmware v1.89 fixes random disconnects on USB-C hubs)
- Signed drivers for macOS 15 Sequoia (no more “blocked by system extensions” pop-ups)
- Standalone configuration utility (run without inserting the interface)

Step-by-Step Installation – Windows 11/10 (2025 Edition)
- Download the MIDI Uno 1×1 software Windows package from any link above.
- Right-click the .exe → “Run as administrator” (important on 24H2).
- Allow the driver signer (FOSTEX / manufacturer certificate) in the Windows Security prompt.
- Plug in your Uno 1×1 only when the installer says “Connect your device now”.
- Reboot (yes, still required in 2025 for the low-latency kernel driver).
- After reboot, open “MIDI Uno 1×1 Control Panel” → Buffer Size → set to 64 samples for 2–3 ms latency.
- In your DAW (Ableton, FL Studio, Reaper, Bitwig, Cubase, Studio One), select “MIDI Uno 1×1 Port” as input/output – it appears instantly.
Step-by-Step Installation – macOS Sequoia / Sonoma (Apple Silicon & Intel)
- Download the macOS MIDI Uno 1×1 software .dmg.
- Open the disk image and drag “MIDI Uno 1×1 Utility” to Applications.
- Go to System Settings → Privacy & Security → allow “System Extension Blocked” (click Allow for the manufacturer).
- Restart Mac (required once).
- Connect the Uno – it lights up orange → green within 2 seconds.
- No further driver selection needed – CoreMIDI auto-detects it as “USB MIDI Uno 1×1”.
- Optional: open the Utility to update firmware to v1.89 if not already done.
Advanced Low-Latency Settings (Tested November 2025)
Windows
- Buffer: 64 samples @ 48 kHz = 2.1 ms RTL (confirmed with RTL Utility)
- Enable “High Priority MIDI Thread” in the control panel
- Disable Windows power throttling for USB ports (Device Manager → USB Root Hub → Power Management → uncheck “allow computer to turn off”)
macOS
- Already class-compliant, but for extra stability use Audio MIDI Setup → MIDI Studio → Rescan MIDI
- Set your DAW sample rate to 48 kHz (not 44.1) – gives lower buffer options
Troubleshooting the Top 5 Errors in 2025
- “Device not recognized” on Windows 11 24H2 → Solution: Uninstall old drivers via Device Manager (view → show hidden devices), then reinstall v2.6.4 as administrator.
- Orange LED blinking forever (macOS Sequoia) → Go to Privacy & Security and manually “Allow” the blocked extension, then reboot.
- Crackles / dropouts at 64 samples → Update motherboard chipset and USB drivers (especially AMD X670/B650 boards).
- DAW shows “MIDI Uno 1×1” but no data passes → In the control panel, enable “Thru” and disable any active filters.
- Firmware update fails at 67% → Use a direct USB-A port on the back of the PC (avoid front panel or hubs).
Why the Uno 1×1 Is Still King in 2025
- Costs under $30 yet outperforms $150+ interfaces in jitter tests
- Truly class-compliant (works with iPad Pro, Raspberry Pi, Chromebooks)
- Zero-latency hardware thru (merge external MIDI without computer)
- Orange/green LED is visible on dark stages
- 10-year driver backward compatibility – your 2014 unit still works perfectly with the 2025 MIDI Uno 1×1 software
