Maybe try a different 3.5mm to 6.3mm convertor, or a pair of headphones with a 6.3mm plug that won't need to be converted

Are you using a 3.5mm to 6.3mm convertor for your headphones? I've had more than a few of these do strange things

Also finding same behaviour with 4-Voice Chorus

Bug in 3.5 FlexoVibe. Rate parameter does not have option to change to note subdivision in HX edit, but can press knob on Helix floor to change Rate to note subdivision. This then breaks link between HX edit and Helix floor, with changes made to Rate on HX edit not affecting Rate on Helix floor, and changes made to Rate parameter not changing knob position in HX edit. Pressing Rate knob on Helxi floor returns Rate to numbered speed and allows HX edit to control Rate parameter again. Same behaviour occurs for mono and stereo versions.

Could due to that pedal model having 22k impedance. Try setting the impedance manually to 1M instead of auto

You could try changing the loop level selector on AC30? What's it set at now?

Are you turning up the channel volume or master volume? If you're turning up the channel volume, you're increasing the signal that gets send out of the FX loop and probably distorting the HXFX return with a signal that's too hot. If you're turning up the master, you're probably running out of clean headroom in the power amp section of the AC30 and clipping there.

Sounds like a ground loop. I used to get the same using 4CM with a Marshall 6100. Solved it buy buying an ebtech (also Morley?) hum eliminator and putting it between the Helix send and the amps input.

I had similar problems a while ago. I use Logic X on MBPro, with Helix floor. I also use an RME babyface interface. In Logic my input device was Helix and output Babyface, as I just prefer using the volume control on the Babyface for monitors and headphones (the dim function is really useful). I was having a similar issue as you, where initially everything would be great, then after an arbitrary amount of time, a huge amount of latency (2-3 seconds) would appear out of nowhere. Unplugging/rebooting either interface fixed the problem, but only temporarily. The fix, for me anyway, was to create an aggregate device, with Helix in and Babyface out. Since using this, I've not had a single repeat of the problem!

Anyone noticed the Alpaca Rouge High Cut control works backwards? The more high cut you dial in, the less is applied.

Sorry to say this still happens in 2.91. Could someone else try to replicate this, please? Go to Global Settings > Displays > Set Tempo BPM Display to Persistent Tapped tempo bpm (on floor unit, or in HX edit) does not update the displayed bpm until you touch the tap switch (not press, just touch). It does update FX using bpm fine now, just not the display.

Just to add to the Tap Tempo issue; There's also an issue with the bpm display on tap button showing the correct bpm. In the video below, i'm connected to a helix floor with usb and running HX edit. I tap in the tempo in HX edit (which is registered correctly and changes the bpm for fx using bpm), however this is not displayed in the tap scribble bpm until i touch the footswitch (touch, not press). Tap video Not sure if it helps debugging at all, or if it's a separate issue.

Try it with something lower gain, it's got loads of gain all on its own. Maybe a edge of breakup ac30 or plexi style amp.

Absolutely blown away by this!

One wrong or missing character in code is all it would take.
