I start to believe that is something like a bug in OS4, couse I'm using hardware and software sequencers from 1993 I'm really familiar with all this.Yes , I did change all the IRQ, same story.I've tried different software seq...all the same.
Interesting, in Cakewalk, if I open Midi Devices window and choose USB Audio (Midjay USB MIDI) than ok..everything normal..for a while..few minutes.But when I retry to record something on a certain track the latency is there.All I can do is to renew midi settings before each take..that sucks BT!!
I have an old paralel MIDI Interface from M-audio, and I'll instal it in a old Compaq lap laying in my basement for years to see if is the same.
