Need help setting up Digitakt 2 + AUM + iPad synths (newbie here)

Hey everyone, I’m pretty new to this whole setup and I’m struggling to get my Digitakt 2 to sequence my iPad synths through AUM. Hoping someone can point out what I’m doing wrong.

What I want to do: Instead of just sampling sounds from my iPad apps (like Synth One or King of Bass), I want to use my Digitakt 2 to send MIDI to the apps and sequence them directly.

My setup: • Digitakt 2 connected to iPad via Anker USB dongle (using the stock DT2 USB cable). • Audio output is from Digitakt 2 directly into my monitors. • Digitakt 2 USB config set to USB Audio/MIDI. • On DT2, I assigned the MIDI tracks to specific channels. • On the synth apps, I assigned the same MIDI channels. • If I play notes directly in the apps, I hear sound fine.

Where I get stuck: • In AUM, when I add a MIDI source, I don’t see Digitakt 2 listed. • If I add an audio channel, load the synth app, and try to use AUM’s built-in keyboard, I also don’t get any sound. • Oddly, I do see Digitakt 2 as a MIDI source option in some menus, but selecting it doesn’t seem to do anything.

I feel like I’ve followed the guides I found, but I must be missing something.
