I use a Apogee Mini-Me which has great converter but the latency is awful.
Using it with guitar rig, even when putting the lateny to 5ms it is much more!!
And after playing a while it is even getting worse! Interresting.
When connecting the Mini-Me via Spdif to my Motu 828, the latency is no more audiable, but I don't want to carry the 828 with me.
Can anybody help me? Is this a usual USB-Interface Problem??
Not sure if this is applicable, but when using an outboard converter (Rosetta 200) with my old Mbox via SPDIF, there was no way of direct monitoring of the signal. In other words, the only monitoring option of the recorded signal was the latent return from the software. The way around this was running one of the analog outs from the converter to the Mbox for monitoring options. The analog signal was not being recorded as my inputs were set to SPDIF, but this did allow direct monitoring...with the track muted there is no latency at all.
Unfortunately, the Mini-Me does not have analog outs, so perhaps you could run the headphone out as a line in to your interface and accomplish the same thing?
