Hi !
I changed from my Roland Octa-Capture to iRig Keys i/o for portability, but it does not seem to work as it should. (iMac 2,66 GHz with 8gig of memory running El Capitan)
First - when I play videos from Youtube, after couple of minutes the sound gets distorted (as if the buffer size is not correct) and the playback is slowed.
No such problem with Octa Capture.
Second - when I use iRig keys i/o with Logic Pro X, the same slowed and distorted sound appears with Sample Tank 4 even with only two or three instruments loaded. And then the error message pops up (audio - midi sync alert) saying something like "Samplerate 33-.... something is detected, please check samplerate of your external interface are the same (I have 44.1 16 bit in Logic)
The i/o buffersize is already set to 1024 but with Octa Capture it was 256 with no problem
