OMEC Teleport ASIO Driver

A custom ASIO driver for the Orange OMEC Teleport USB guitar pedal on Windows, built for low-latency live performance with Gig Performer and other ASIO-compatible DAWs.

Why This Driver?

The OMEC Teleport's input stage runs hot, causing digital clipping before your DAW can process the signal. This driver provides:

• Digital input gain attenuation -- tame the hot input before it reaches your plugins
• 32-bit float ASIO buffers -- full dynamic range, zero conversion overhead
• Auto Input Level Set -- click, play your loudest, and the driver sets gain to target -12 dBFS
• Soft limiter -- tanh-based soft clip at -1 dBFS prevents hard clipping on output
• Dark-themed control panel -- embedded in the DLL with real-time peak meters, gain sliders, and calibration controls
• Low latency -- tested clean at 64-sample buffers
• Drift correction -- ring buffer trimming keeps latency stable over long sessions

Control Panel

Architecture

The driver uses WASAPI shared mode as its audio backend rather than WinUSB or WASAPI exclusive mode. This avoids known timing issues with USB Audio Class 1.0 (Full Speed) devices in exclusive mode, while keeping latency low.

Guitar -> OMEC Teleport (USB) -> Windows inbox USB audio driver
  -> WASAPI shared mode (float32) -> Ring buffer -> ASIO float32 buffers
  -> Gig Performer / DAW -> ASIO float32 output -> Ring buffer
  -> WASAPI shared mode (float32) -> OMEC Teleport (USB) -> Amp/Monitor

No custom kernel driver, no INF file, no driver signing required.

Requirements

• Windows 10/11 (64-bit)
• Visual Studio 2022 or later (Community edition is fine) with C++ Desktop workload
• Steinberg ASIO SDK 2.3+ (see ASIOSDK/README.md for download instructions)
• Orange OMEC Teleport pedal

Building

1. Obtain the ASIO SDK -- download from steinberg.net/asiosdk and extract into the ASIOSDK/ folder so that ASIOSDK/common/asio.h exists.

2. Open the solution -- double-click OmecTeleportASIO.sln in Visual Studio.

3. Select configuration -- choose Release | x64 (or Debug | x64 for development).

4. Build -- Ctrl+Shift+B or Build > Build Solution.

5. Register the driver -- run installer\install.bat as Administrator. This calls regsvr32 to register the ASIO COM server.

Installation (Pre-built)

If you have a pre-built OmecTeleportASIO.dll:

1. Place it in a permanent location (e.g., C:\Program Files\OmecTeleportASIO\)
2. Open an Administrator command prompt
3. Run: regsvr32 "C:\Program Files\OmecTeleportASIO\OmecTeleportASIO.dll"

Or download the latest release zip, extract, and right-click install.bat > Run as administrator.

Setup

Critical: Match Sample Rates

Both the OMEC Teleport capture and playback endpoints must be set to the same sample rate in Windows:

1. Right-click the speaker icon in the taskbar > Sound settings
2. Scroll down > More sound settings
3. Recording tab > right-click "Line (USB AUDIO CODEC)" > Properties > Advanced > set to 48000 Hz (or 44100 Hz)
4. Playback tab > right-click "Speakers (USB AUDIO CODEC)" > Properties > Advanced > set to the same rate

Mismatched rates will cause pitch shifting and distortion.

Using with Gig Performer

1. Open Gig Performer
2. Go to Options > Audio Setup
3. Select "OmecTeleport ASIO" as the audio device
4. Set buffer size (128 recommended; 64 works if your system handles it)
5. Set sample rate to match your Windows Sound settings
6. Click Apply

Auto Input Level Set

1. Open the Control Panel > Input Controls tab
2. Click Auto Set Input Level
3. Play your guitar at its loudest (hardest strumming, loudest pickup) for the full countdown duration
4. The driver measures true peak and sets gain so peaks land at -12 dBFS (top of green, barely yellow)

Peak Meter Colors

Color	Level	Meaning
Green	Below -12 dBFS	Safe operating level
Yellow	-12 to -3 dBFS	Getting hot
Red	Above -3 dBFS	Clipping danger

Troubleshooting

Problem	Solution
"Can't Start Device" in DAW	Ensure OMEC Teleport is plugged in and shows in Windows Sound settings
Distorted / robotic sound	Check that capture and playback sample rates match (see Setup above)
No sound at 44100 Hz	Set both endpoints to 48000 Hz in Windows Sound settings
Driver not listed in DAW	Run installer\install.bat as Administrator
Device not found after replug	Close and reopen your DAW -- WASAPI re-enumerates on restart
Latency increases over time	Drift correction handles this automatically; if severe, restart the stream

Uninstalling

Run installer\uninstall.bat as Administrator, or:

regsvr32 /u "path\to\OmecTeleportASIO.dll"
