2. Which Soundcraft Mixers Require Driver v3.20?

While newer Soundcraft devices may use class-compliant USB audio (no driver needed on macOS), many professional and prosumer Windows systems require v3.20 for full multichannel functionality. Compatible mixers include:

• Soundcraft Signature 12 MTK (12-in/12-out)
• Soundcraft Signature 22 MTK (14-in/12-out)
• Soundcraft Signature 16 (with USB audio interface functionality)
• Soundcraft Impact (digital console series)
• Soundcraft Ui24R (rack-mount digital mixer, early Windows drivers)
• Soundcraft Si Expression (when used with USB audio card option)

Important Note: The v3.20 driver is not for the older Soundcraft Spirit or MPM series, which use legacy USB 1.1 protocols.

If you own a Signature MTK series mixer, the v3.20 driver is almost certainly the recommended or required driver for Windows multitrack recording.

• Uninstall all previous Soundcraft drivers via Device Manager > Sound, video and game controllers > Right-click Soundcraft > Uninstall device (check "Delete driver software").

Conclusion

The Soundcraft multichannel USB audio driver v3.20 is more than a piece of software—it’s a bridge between analog warmth and digital precision. While newer drivers exist, none have matched its combination of low latency, channel count reliability, and Windows 10 harmony.

Whether you are a podcaster tracking multiple mics, a live engineer recording a full band, or a producer using the Signature MTK as a summing mixer, v3.20 remains a trusted tool. Install it carefully, configure it wisely, and it will serve you for years.
