Midi Guitar 2 + Behringer404UMC HD ---- can't get tracking going

Hi all,

Trying this app after recently upgrading to faster iPad (2018 pro , up from Air1).

Struggling to get the app to track/convert the input

Got USB C hub, Behringer 4port, bass guitar plugged in to port 1, all other ports are empty.

Can't for love nor money get conversions happening. I can hear my bass no problem, the VU meter is somewhat low. Upped volume on my guitar, helped, but still no converted midi sound in my headphones.

Clearly my input output settings are probably wrong but it's driving me mad!

INPUT DEVICE shows. 'iOS AUDIO'. - I would have expected UMC404HD to be selectable?

Output device the same situation.

Input channels and output channels I have selected UMC404HD which I think is correct...

I followed the quick start guide on the apps website. . This is pretty much what they suggest...

I'm not sure what's wrong..

I tried this 5 years ago but was using iRig Pro to input the guitar.

I know I'm using a usb C hub now but there's no question it's picking up the 404hd... The problem is the same with any instrument I pick (piano, synth) etc..

Have the iPad a Shutdown then back on..

Any ideas chaps?

  • With a screenshot or a video I will try to help you.

  • In MG2, there is a panel called MidiFX.
    You have to set one of those to Midi Output.
    In your image, it looks like you have only Sustain and Transposer loaded up.

    You're using a bass now and when you tried it five years ago you were using a guitar? Maybe it just doesn't track well with bass? Got a guitar you can try it with?

    (Yes, I know a bass is a guitar, but you know what I mean...)

  • It doesn’t track the low octave on my bass.
    It starts tracking at the first octave E for me.

  • If I remember right, and it's been a while since I looked, it doesn't do bass on iOS. There is a Mac/PC version that does bass I think. Kinda not surprising if it is still this way, bass is hard to do -- not enough information in the low registers to get past latency issues.

  • No no. I always used to use my bass with it. It definitely works.

    Hopefully it's just the setting thing Cracklepot mentioned..

  • MG2's range is limited to standard guitar range (-2 semitones...it can track down to a low D if you drop the low E string down a tone). It will respond to some part of your bass' range.

    Also, depending on range, you will not experience peak pitch-to-MIDI speed as you'd get from playing in a higher register on a standard guitar...That's physics.

    Other than that, the INPUT/OUTPUT device should populate automatically.

    You didn't mention if you're using it in standalone or AUv3 mode.

    Hi guys, thanks for the replies

    I've been trying out BiasFX2 just to see if that app picks up the bass/behringer404.

    Things are a bit strange. I've tried GarageBand, BiasFX2 and BiasAmp with my BehringerUMC404HD.

    • if I check the UV meter in any app, I can see it registering as I play, but try as I might, any presets I choose (any app), there's no difference in sound.

    The usb hub seems fine... It picks up my M-Audio keyboard, and my AKAI LPD8..

    So apps are recognising my Behringer404 interface... And I can select different channels no problem. I've bass guitar in channel 1, select chan1 in an app, --- can see VU read changing.

    I don't know what's going on here.

    Here's a video of me trying it out with MG2, can anyone spot what I'm doing wrong?

    (Stand alone btw)

  • From what you describe, it sounds like none off the apps see the input from it.

    Do you have Audiobus 3 or AUM? The first thing to do is suss out the the input device without the further complications of apps processing the output.

    I’d unplug absolutely everything from your iPad.
    Reboot.
    Launch AUM or Audiobus 3.
    Plug in your interface to your iPad.
    See if the interface shows up in the list of available inputs.

  • Maybe the 192 kHz is the problem. Did you try 44.1 or 48 kHz?
    I think you can set the hardware samplerate and buffersize in the driver on Windows...

  • In the tracking section, try lowering the noise gate to zero to see if it starts tracking.
    If it does track with noise gate at zero, then be sure to only raise the gate threshold enough to clean up errant noises, but not block the notes you want to track.

    If it is class compliant, you can set the sample rate on the iPad.

  • Well I have one and that is what I remember. Put it in 48khz when I got it and never had a problem. Also with the 404hd there is this strange thing that you have to turn up the volume on the ipad to get audio coming out of the interface.
    Turn the mix knob all the way to computer otherwise you hear your guitar through the direct monitor in the mix.

  • It looks like he has it set to 44.1kHz. The 192K that is there is just the name Behringer gives to the device. It says that no matter where you have it set.

  • Yes I saw that but I clearly remember that this 192kHz mode is special, and does not allow software switching. You can record 44.1 kHz, but this will be a software conversion...
    Anyway I am curious if this solves his problem. Good luck.

    Hi,

    So, I think for debugging purposes you have two completely different issues to suss out/

    ======== ISSUE #1- Is the guitar's audio making it into your iPad with suitable level.

    I would use something OTHER than the MIDI Guitar app to do this. It will be more straightforward to see what is going on.

    If you have AUM or Audiobus 3 it will be easy to suss this part out in them as they will show you the name of the input driver being used. AUM has a handy meter that will show the level of the signal coming from the driver.

    ======== ISSUE #2 - Routing the MIDI from the MG Out to where you want it to go.

    Don't even bother with this issue until ISSUE #1 is sussed out.

    About the MIDI, it looked like you were routing the MIDI back to your Behringer interface. Was that your intent?

    When you finally get ISSUE #1 sussed out, you should confirm that Midi Guitar is working well with its internal sounds (and that the direct signal can be heard, too). I wouldn't spend time working on the MIDI routing until the direct signal sounds right in MG and you have it working with the internal sounds.

    I expect this is completely unrelated, but I’ve gotten temporarily fooled a few times by plugging in my Apple earbuds after my interface. They take over as the audio device. I’ve seen the meters move but that’s from the guitar coming through the earbud mic. Depending on my state of sleep deprivation this has flummoxed me from a few seconds to minutes. :D

    Solution is to unplug and teplug the interface so that it takes over.

    Sorry, I can’t watch the video right now so I don’t know if this is even remotely related to your situation.
