RME Digiface USB – what latency did you manage to run? – Page 2 – Hardware (Instruments and Effects) Forum

I have one also. It’s great.

I run the phones/line out to active monitors and S/PDIF out to a headphone amp if I want to use phones.

Haven’t tested RTL but those figures already mentioned seem usual. Reaper reports “~0.7/1.7ms” 32smp 48K. Likewise in FL Studio. Cubase says 0.73/1.77. No surprises as it’s what is being reported. But RME units are known to report accurately.

Essentially I don’t have to fiddle around to get usable MIDI keyboard input, I can leave it on 256smp and I can’t really hear or feel any lag – which is why I bought the unit. The benefit is that at 256 I don’t typically run out of CPU after adding VSTs.

Only exception is if I’m using my MIDI drum pad, in which case I usually take the buffer lower. Seems I notice delay more with drums for some reason. Even then I never need 32. 128 or 64 is just fine.
