All good, the issue was that completing the upgrade was the exact moment the battery in my active pickups started to die. False alarm!

Everything seemed to go fine wiht my upgrade, but I'm not getting any sound now. I have a PC+, nothing has changed there. Followed all the instructions, reset and restored, no gain. Checked all the global and patch settings. No sound would be one thing, but I get a very very low signal on high gain patches. Can anyone assist?

As it says, are there any suggestions for virtual instruments that just output a basic DI guitar signal from MIDI that I can then amplify using the Helix native? I don't need the VSTi to have any in-built amplifiers. For quick demoing.

Hmm, are you sure L6 link is even a different cable? I thought it was just referring to the line protocol being slightly modified. Pretty sure I'm just using an AES cable, controls everything perfectly, but digital out still works. I'd have to doublecheck on the current firmware though.

This is something of an understatement! I get constant lockups on my HX Effects, and less frequent on my Helix when connecting to both through any USB hub (tried 4 different ones). This is definitely a bug that needs fixing.

A hum might just be a ground loop. How are you powering the pedals?

If you have still have the problem, after say dropping send by 3 and raising return by 3 to equalise the volume again, then the problem was not sending too much signal to the ODs, it will be something else. But you can isolate the problem to a particular spot in the chain in that way or by switching loops in and out. Try switching Loop1 to line level and you'll see what sending too much signal to your ODs sounds like!

Hi there, You should be able to run the OD pedals in the HX Effects FX loop just fine, what are the exact problems you're having? You mentioned noise/levels/yada but more specifically? Anyway this cabling set up should work fine and give you a better overall solution, but you'll still need to get the levels right. The first thing to check is that your HX Effects FX loops is set to instrument level in the global settings. Even then you can sometimes overload the pedals, so try dropping the send level 3dB at a time until you get a good tone. Bad tone from sending the pedals too much signal should be pretty obvious. I think the level the of amp's FX loop depends on the amp, but set either to instrument or line in global settings, then perhaps adjust the return level down a bit if more headroom is required. Finally, the level of the output block. Just make sure it's the right signal level for the amp. Compare the amount of gain/level with just running the guitar straight into the amp to get this right. cheers, B

I agree it's roughly 10dB difference between the models and the Flat modes, but it will depend on the amp as well. I have to adjust slightly for different helix presets

But see my post above and show that it's not the helix that is badly adjusted - there's two points where a digital is converted to analgoue of vice versa. Someone with another digital cab would need to compare to be sure.

Well to be accurate it's a much smaller pop but still a pop for me.

Shall I repeat myself? I'm a bit shocked this information is not on product page, OR in the actual manual with the other tech specs.

While a possibly useful post, I am not sure how this is related to clock signal getting to ground. An RF/EM inteference problem would be a different thing altogether.

It's important to note this is NOT the same as the L6 Link carrying MIDI messages, it's probably a proprietary way of controlling the PC+. And no mention of MIDI above. What I suspect Line 6 are doing in 2.80 is creating a customised message format that will fit inside the existing AES frames. Unless AES already supports carrying MIDI messages (which a quick google suggests it doesn't) I would highly doubt Line6 would have the skills or the will to modify the AES protocol to carry MIDI all on their own. It's relatively simple though to send what looks like a regular AES message that carries PCM audio but has some special bit pattern that the PC+ will be programmed to recognise as a control message not an audio message. Or they may just use the existing 'sideband' capability with the protocol (there's already a way to send a low-fi audio e.g. like a push-to-talk message with the high-fi audio signal). Again this is roughly 1000 times easier than adding full MIDI to AES. Just a guess...

Which style of input jack are you using on the powercab? For me the pop only happens on the analogue jacks.
