> Note that since the server program exposes an HTTP server you can actually navigate to the IP address of your PI from any device connected to the same wifi and control your pedal chain from there.

That's a killer feature for me, hiding at the end of the README. I have a Fractal Audio FM3[0] at home, and the only way I edit my patches is using their editing software over a USB connection to the device. Adding the ability to program (and even control) my patches live over any wifi-enabled device is even cooler!

Don't go leaving it exposed if you connect it up to the venue's WiFi, if you're playing live. ;)

I had sketched an idea for a web ui that would talk to a VCV instance, outputting signals to a real eurorack device with an expert sleepers module… need to keep hacking on that.

Don't run wifi and real-time software at the same time.

[mattkrause]

Using wifi to trigger real-time software is often a bad idea, but using it to configure responses to future triggers isn’t necessarily so bad.

[rerdavies]

The Raspberry Pi 4 has separate USB hubs: one for WiFi and ethernet (an internal hub), and another for external USB ports. The USB port service loop will run with higher priority, so there doesn't seem to be any serious adverse affect.

The same isn't true for SD card access, which does cause dropouts. I've seen a video that suggests that disabling power management for the SD card hardware will correct the problem -- specifically that changing power state causes a 3ms delay. But I'm not quite sure how to go about disabling that on a Raspberry Pi OS.

. WiFi doesn't seem to affect audio latency. That's not true for Raspberry Pi 3, where WiFi and USB ports do run on the same USB hub.

[mr_sturd]

The only signals going over WiFi here would be controls for the virtual pedals.

[jcelerier]

Just the beacons you get from other routers around can be enough to create disturbances

[zamnos]

What wireless technology would you recommend instead then?

[worik]

none, of course

[zamnos]

Lol ok. Meanwhile the rest of the industry is moving on. I mean, how do you even do an wired connection to a drone? A lot of times guitarists will perform on a stage and the clients wants aerial views without the cost of a crane. Do you just tell them you can't do it and have them go with a different company?

[bacon_waffle]

I'm a little confused by this thread - it seems like you suggest that the drone should be controlled by the SBC in an effects pedal, that the guitarist is using to provide low-latency audio processing? As a techie and perpetual-intermediate musician, that seems a bit odd...

But, incidentally, at my day job I'm working on an embedded Linux system where audio latency matters, and which may well wind up with a WiFi radio (where latency probably doesn't matter so much). So, I'd like to understand issues in this space.

[pdntspa]

With special nonstandard proprietary wireless protocols is the answer you're looking for. The same shit wireless stage mics use. Or control over cellular data. I can guarantee you they aren't pairing them to a 802.11 router. Lol ok.

[darkwraithcov]

The core audio driver does a pretty good job with this.

[nightowl_games]

Somebody should make a device that plugs into a fractal axe FX and hijacks the USB connection and exposes a web interface. Now that'd be cool!

[zamnos]

There are a bunch of USB over IP boxes you can buy, so it depends on the m what you're looking for, port-wise. That plus a wifi router gets you what you're looking for.

[obituary_latte]

Always hear about the Fractal Axe FXIII--seems like the gold standard in guitar FX. Didn't realize they had smaller, non-rack-mount form factor devices. Very interested in trying out the FM3 now that you brought it to my attention. Thanks!!

[tecleandor]

The Mod Dwarf (and its predecessors) also allows web control and it supports standard LV2 plugins :)

[Blackthorn]

The first site is remarkably brief about its actual capabilities. Is there somewhere with more information about it?

[tecleandor]

Simplifying a bit: It's a pedalboard with a Linux SBC inside where you can load LV2 plugins and chain and route them as you wish. It has a sleek web interface for management and some short of "pedal store". Like an advanced multieffects pedalboard. Originally the MOD devices where crowdfounded.

There's a small introduction video: https://www.youtube.com/watch?v=5USQ7BsZ054

And Modep (as @tcrenshaw wrote in another comment) this is a MOD emulator for Raspberry pi, just in case you want to play with it: https://blokas.io/modep/

I think the hip new guitar effects/sim is the Quad Cortex from Neural DSP. I've seen Kiko from Megadeth uses it for his live shows.

[bjelkeman-again]

I think the AxeFx has more virtual knobs, but the QC is easier to use, and has Kemper-like sound capture tech.

[ganoushoreilly]

The QC is my go to pedal these days. I have a Helix (rack) and a Kemper (rack). While there have been some hiccups on software it really is a solid little box.

[bjelkeman-again]

Yeah, I switched from HX Stomp to the first batch of QC. Very happy with the result.

[theflyinghorse]

AxeFX is absolutely insane in amount of control it gives you over your tone. I would say far too much control. Probably the best tool for a tone tinkerer.
