Soundcraft Multichannel Usb Audio Driver V3.20 May 2026

While Soundcraft maintains a "stability-first" approach to driver development, version 3.20 addresses several backend issues:

The Si series digital consoles use this driver for virtual soundcheck and multi-track recording of live shows. The driver v3.20 fixes a long-standing issue with channel mapping in Cubase and Nuendo.

These are the flagship analog/digital hybrids. The "MTK" (MultiTrack) designation allows you to record each channel pre-fader directly into your DAW while simultaneously returning the master mix from your computer.

As of 2025, Harman has not announced a successor to v3.20. Given that many Soundcraft products are being phased out in favor of the new AMX and dbx lines, v3.20 may be the final feature release for the legacy USB multichannel driver family.

However, the driver is open-source aware – several community developers have reverse-engineered the USB protocol to create Linux ALSA drivers based on v3.20’s descriptors. For Windows users, though, this remains the gold standard.

Here is the relevant information and a placeholder text block for the Soundcraft multichannel USB audio driver v3.20.

Note: This driver version (v3.20) is historically associated with Soundcraft Signature MTK series (12 MTK, 22 MTK) and Ui series (Ui12, Ui16) when used in USB audio interface mode. Please verify on the official Harman/Soundcraft website as newer drivers (e.g., v4.x) may be available.

As of 2025, Soundcraft continues to support class-compliant USB on new mixers (e.g., Ui24R’s updated firmware). However, for owners of the beloved Signature MTK series, the v3.20 driver represents a high-water mark of stability. With no further updates expected, many engineers run a dedicated Windows 10 partition solely for this driver.

If you are considering purchasing a used Soundcraft Signature 22 MTK, ensure the seller includes the v3.20 installer. Pair it with a lightweight DAW like Reaper or Tracktion Waveform, and you have a 14-in multitrack live recording rig for under $500.
