TX-6 USB Audio Artifacts / Crackling with Torso S-4 (Host)

Hi everyone,

I’m trying to run a “powerhouse” compact setup by connecting my Torso S-4 directly to the TX-6 via USB. The S-4 sends all 4 tracks plus the master output to the TX-6.

It’s an incredible routing dream, but I’m plagued by constant digital crackling and artifacts.

What I’ve tried so far:

• Power issues: Initially, I thought it was a ground loop or the S-4 struggling to power the TX-6. However, disabling the USB Charge function on the TX-6 didn’t solve the issue.

• Cabling: Tried different high-quality USB-C cables, but the noise remains.

My questions for the TX-6 experts here:

1. Is the TX-6 particularly sensitive to the clock stability of an external USB host like the S-4?

2. Has anyone successfully managed multi-track USB audio input on the TX-6 without pops and clicks?

3. Could this be a buffer issue on the TX-6 side, or is it more likely that the S-4’s USB implementation is the culprit?

Any advice on settings or specific firmware tweaks would be much appreciated!

I have not tried with a TX-6, but experienced the same thing with an OP-XY.
