Which Soundcard is best for Loopy Pro. UMC 1820 is not working well.

I currently have two soundcards. One Scarlett 2i2 and one UMC 1820. Since I have a lot of gear connected to the UMC i would like to use it with Loopy Pro, however the signal both in, and especially out is very low. I can't actually hear anything while monitoring with my headphones through the UMC. The Scarlett works much better, the signal is strong and the headphones works perfect.
Does anybody else have this issue?
The UMC works without problems connected to my Macbook Pro.
For Loopy Pro I use an iPad 6, which of course has its limitations but as said, works perfect with the Scarlett.

  • Personally I would choose an audio interface with lowest latency as possible. I'm using the RME Babyface Pro FS. RME stuff is rocksolid and super low in latency.

  • @ottomilde The Behringer UMC audio interfaces have a flaw with iOS devices related to volume levels. I find I have to do two steps every time I connect mine:
    1. Manually press the iOS volume levels to max on my iPad after connecting the audio interface
    2. Go into the settings of my audio host (Loopy Pro, AUM, etc) and manually set each input channel to +24 db

    This allows proper recording and proper audio levels for inputs and outputs. I’ve never figured out why it needs to be done this way. I’m guessing Behringer has some errors in how they implemented the “Core Audio” firmware on their devices.

    Try this out and see if your problem is solved. It fixed the issue for my UMC 404HD, so I’m expecting the UMC 1820 would have the same issue and same fix.

  • Also, latency should be a non-issue. You can set the “sample rate” and “buffer duration” in Loopy Pro’s “system settings” menu. It can go as low as 64 frames buffer.

    The Behringer UMC interface should respect the settings of Loopy Pro as the audio host.

    Keep in mind, do a hard reboot of the iPad then open Loopy Pro and don’t open other iOS apps that deal with audio (like Safari, YouTube, etc) because sometimes they interfere with iOS audio settings at a system level.

    System settings play a part, but so too does the audio interface, latencies vary.

  • @Icoustic great info thanks. :)

    I was just trying to steer the original question away from worrying about latency, since it has nothing to do with his volume problems. (Not sure why latency was brought up in this thread).

    but since you mention it, yes the hardware unit itself will add its own latency at every buffer setting. I was glad to see the UMC204 on the list you linked, and that it was on the average-good end of things for all buffer settings.

    I really think @ottomilde should be able to get a usable setup going with the UMC 1820

    Because the thread topic includes, “which sound card is best”. I’m also using a Babyface Pro FS at 64frames and found Amplitude introduced noticeable lag playing guitar whereas THU Overload did not.

  • Great tips thanks! I’ll try and set the levels higher and see how that works.
