All the above. Check voltage from power supply with a voltmeter. Jiggle the Stomp on/off switch. And for sure check power at the wall plug. If you've checked all the obvious, then it doesn't sound good. It doesn't sound at all.

"Wait Time" setting slipped by me. Good to know it exists if its ever needed. Still, that could only account for up to a 1 second delay, not the 5 seconds hes reported. That's crazy. Could be a wormhole.

Logic Pro. Its a standard set of buttons that appears above the current plug-in window...

Of course if you really get down to it, you need a sound engineer out front who can not only shoot out the PA, but also tweak the EQ of every channel to fit the room acoustics. I don't have a sound engineer. I don't even have a roadie. So I made 6 EQ smiley curves (from flat to drastic) for my PA that I can use at a gig. That as close to a bag of magic as I'm gonna get for now. A few years ago I used a dBX Driverack which I would use to "pink" a room. It would level out the PA EQ using pink noise and a calibrated RTA mic. It worked amazingly well and the result sounded pristine. But there were usually people in the venues I played so it annoying. But if you are setting up good sound at a venue before people show up, its pretty darned cool magic.

That's wacky. It's not normal for MIDI commands to be delayed. Make sure you don't have any sort of send/receive loops going on (enable Rx and enable Tx set on multiple MIDI devices). I can't imagine what might cause such a delay. MIDI commands are sent instantly from my Stomp running 3.11. Have you tried other troubleshooting? For example, hook up just your Helix to MIDI monitor software running on a computer, via USB and test.

All my old stereos back in the 70s had a LOUDNESS switch on them intended for making things sound better at low volumes. It basically turned up the bass and treble, but perhaps they mysteriously applied a carefully calibrated Fletcher Munson curve. I like the idea of a volume knob that would compensate the EQ as you turned it up or down. Seems like a simple thing to engineer. And perhaps something easy to market. Like laundry detergent magic crystals.

I use an app that sends the Helix Tap Tempo command (CC 64, 64) on quarter notes (from MIDI clock). This is the same as tapping the Tap Tempo button. It takes about 10 seconds to accurately lock onto the tempo, and its precise for me. After 10 seconds, you can stop sending the messages and Helix will retain that tempo until you reset it, or select another preset.

This is a really old thread, but I'll add a comment in case someone is doing searches. I used an HX Effects for years for acoustic guitar (winery/coffee shop gigs), but sold it and got an HX Stomp after Line 6 added Command Center support. I love the size of the unit, it has everything I need for acoustic guitar tones (I don't use the amp/cabs), its smaller than the HX Effects, and I think the resale market will be lots larger than that for the HX Effects should I ever want to sell it. For me, its perfect.

For those of us who rehearse in a small space who can't turn things up, but play at louder volumes (and have good EQ software for their monitors/PA) I'm wondering if anyone has experimented with applying a sort of Fletcher Munson EQ curve to simulate volume change effects? Did a little digging, and found this discussion on the Kemper site: https://www.kemper-amps.com/forum/index.php?thread/11631-fletcher-munson-curve-eq-for-playing-at-different-volume-levels/ and found other threads about others doing similar stuff for different applications (including mastering and live performance. If I free up some time I may experiment a bit....

Here's what worked best, and its easy to set up and tweak: split the path after the amp, and on the lower path add - a Simple Delay set to eighth notes (synced), 100% mix, 0% feedback - a second Simple Delay, set to 1/32 triplets (synced), 100% mix, 0% feedback. This works because the first delay is providing a precise eighth note delay (0% swing). You don't hear it, but its passed on the second delay which then delays the eighth note by a little bit more, to provide the % swing needed. The time increment of the second delay can be adjusted as needed to obtain the amount of swing needed (use ms for you need greater precision). Then blend in the level of the final delay back into the main path as needed.

Thanks all ... I'll experiment with these suggestions today.

I'm trying to set up a guitar tone that is synced with tempo and pulses with swing eighth notes. A delay or tremelo fx would work, but are there any effects in Helix that have a swing parameter?

Many have complained. Nothing has changed. Your only solution (for now) is to rename them.

You'll save a lot of headaches if you just invest in an official Apple camera connection kit. It just works. I recommend the USB 3 model ... it costs more but it will keep your Ipad mini charged during performances.

MidiPad 2 is currently my favorite free controller app. Its customizable, low latency, and supports CC, notes, program changes, etc. It'll turn your tuner on and off in the wink of an eyeball.
