Positive Grid Riff Firmware

[Aleck Cobbs]

Ive just gone back to my Line 6 Sonic port VX (the VX is the one with the built in mic and, crucially a headphone socket). I did actually want to use at the mic, but it's still a good sized unit for guitar in bed. My other favourite, for just guitar, is a Fender slide interface, again pretty old, but you can pick them up cheap and they are compact and straightforward.

I can't remember if I've used them direct to USB-C as I generally use them with a usb-c splitter (PD and 1x USB 2 socket). The Sonic port is micro usb (as well as bespoke lightning MFI connection), the Slide is mini usb.

Whilst I'm here, I also continue to use, a TC Helicon Go Solo and, even more ancient, a Sonoma Guitarjack 2 - I have these both attached to different guitars and both are very small, light and reliable - again, not USB-C, but you can adapter your way around that without too much trouble.

I should also mention the Mighty Plug Pro, which is more of an app controlled headphone amp - I love it for 'no setup' bed playing. It CAN work as an interface, but that's a bit more of a challenge as you need a hefty (2A plus) power source (for lightning at least) and some setup in the app. The output connection on the Pro is USB-C, the older non pro version is usb micro.

I had the Apogee Jam+ at home for a day and from what I remember the latency was more or less the same as the IKM iRig HD2 had. (RTL 16ms at 48kHz/64 samples). This could be a deal breaker for many guitarists (including me).

I have NuX MPP and can confirm that you will need an external power source (USB hub) if you have iPad with Lightning.

Newer USB-C iPads shouldn't have problem to powering MPP. I'm using MPP along with my iPad Air 2022 without any issues.

There is one shortcoming that bothers me. If you want to tracking with software ampsims (Nembrini, ToneX, ..) you will have to run Mighty or Mightier app at first and set wet to 100% in USB settings. And use completely empty MPP preset slot of course.

If you are satisfied for what MPP provide itself (sims, effects) you don't need this initial "dance".

@wingwizard to clarify, are you looking for a device you can use without any software, as in plug in guitar and headphones and it works by itself and has sims/fx inside of it? Or do you intend to plug it in as an interface to an iOS device?

With this Onyx app. I have double checked results with RTL utility for Windows.

Referenced interface was my RME Babyface Pro FS. The RME is faster on Win than on iOS probably thanks to native ASIO drivers. (2nd screenshot)

I already commented latency in some thread here but can't find it now. So here is my results again:

The other one was a positive grid riff. I read that it has built in gate, probably to juice the signal to noise specs, and no firmware can adjust it. Makes some odd cutting noises, not major but annoying
