The IR block in the patch that you use - what does the Level parameter read? Default is -18dB which with most IRs is about as loud as bypassed. IRs are captured frequency responses of mic'ed cabinets (at least that's what they are used for most often). Playing a mic'ed cab simulation into a cab doesn't make much sense in most cases. It can sound cool though. Generally: Play into a power amp without IRs but use a signal with IR for direct recordings or to feed FOH.

Das kann ich definitiv hören. Hast du einen weiteren IR-Loader als "dritte Meinung"? Könnte es sein, dass bei NadIR ein HighCut bei 20kHz an ist? Wenn du im Helix den HighCut im IR Block auf 20kHz (höchster Wert) stellst, dann sollte es ziemlich gleich klingen.

Das sieht gut aus, aber probier' mal Export mit 48kHz - das ist die Samplerate vom Helix. Nebenbei: Die Sache spielt sich bei 15kHz und drüber ab, ich könnte das nicht hören - und ich bezweifel stark, dass das den Sound dünn und fizzy macht.

The dry through should work for your return. When you get burried in a mix that can have multiple causes. This might help: listen to your amp from another angle use appropriate volume often making your sound more mid-focused helps try to find a complementary sound that works with the 2nd guitar

Look at the exported IRs in the time domain (amplitude over time graph instead of amplitude over frequency) and see if they need to be truncated. In other word: is there silence at the start of those IRs?

One data pin probably is not connected.

Using MIDI for controlling that amp is easy and described in the amp's manual. You don't even need to set it up on the Helix if you switch amp channels with presets. And with Snapshots the Command Center isn't hard to set up either. You / he can ask here if questions arise.

That amp can be switched with MIDI. No problem.

The Input block has a parameter called Gtr Pad. Set it to ON. Or set Gtr Pad to Global and Global Settings -> Ins/Outs -> Input Level to Line.

Sure, Controller Assign the expression pedal to the Level parameter in the Output Main L/R block.

The Fender Mid Boost Eric Clapton can boost the signal 25dB. That's WAY too much for the HX's input to handle. Definitely use the HX's Pad although it is only -7dB which isn't remotely enough to handle the full boost capabilities of the Clapton.

You could try this: engage the Feedbacker and save it as User Default (press and release both < and > PAGE buttons, then press Knob3). Otherwise contact support about this.

I don't have the HX One so I can't verify that. On my HX Stomp it can be saved engaged and does immediately feedback. You can contact support and ask whether saving it engaged is possible.

The feedbacker is made like this for a reason. It is supposed to feedback when you trigger it - not at preset load. But you can save the preset with the engaged feedbacker if you want to. The MIDI messages are correct. BUT the timing is suspicious: the CC messages are send one millisecond after the PC messages. The HX One is probably busy loading the preset in that moment and ignores / discards the CC message. So there are your two solutions: save the preset with the feedbacker engaged or add a small delay between the PC and the CC messages.

These are MIDI PC messages and we were talking about CC (or alternatively NoteOn) messages. You don't need to send Bank Select messages btw. HX One only has one bank and ignores them anyways.

Not sure how a Helix manual talking about Command Center's sending toggle CC commands should help the issue. It's about the HX One not reacting to MIDI CC. We are in the stage where we verify with a MIDI monitor that the RJM actually sends the correct MIDI data..

I wouldn't conclude things that fast. Do the MIDI monitoring (see prev post) and come back with results.

Hmm weird... CC#1 and CC#4 should do the trick. You could try sending a MIDI Note ON message C[0] - that also triggers Bypass/Enable. You could also use a MIDI monitor program like MIDIView and see what MIDI messages HX One actually recieves. That might help getting a clue of what goes wrong.

To confuse things a bit more the MXR Timmy switch goes from left to right: MXR left <> Teemah! up MXR center <> Teemah! center MXR right <> Teemah! down

I mean changing presets with MIDI as in: sending MIDI-PC (program change) messages to go to a different preset. That is an easy test to see if it reacts to MIDI messages at all and excludes errors like defective cable, wrongly connected, wrong MIDI channel etc.

The Feedbacker is one of those effects that are bypassed by default - like the Ratchet or Tesselator. Try CC#4 (Bypass/Engage) with value 127. If that doesn't do it: does changing presets with MIDI work?

@Detgyver To clarify: "5.5mm/2.5mm" means 5.5mm outside diameter, 2.5mm inside diameter.

Yes. I have one and it even works with the USB 3 of my computer. But the Birdcord PD ➔ 9V (USB PD Voltage Converter) for USB-C is the better choice for modern USB-C PD power banks and power supplies.

Boss PSA 230S is 500mA - not strong enough. A power supply works with the Stomp if it is: 9V DC 1A or more 5.5mm/2.1mm 5.5mm/2.5mm barrel plug center negative

Yes. The volume block (like any other block / parameter) can be controlled by an expression pedal but not by a volume pedal.
