USB Audio Interface not operating correctly
Posted: Fri May 27, 2011 7:13 pm
Hi,
I'm having trouble using a new USB audio interface and I'm out of things to try. Hope someone here
can help.
The problem is with the midi i/o. The usb interface has ports for midi in/out. MTS playback
operates normally with no errors, my USB interface says it's sending midi out, my synth
apparently receives it, but reports "midi buffer full" and "midi communication error".
Initially, MTS reported a problem with my "mixer" when I tried to record using the new
interface. It recommended using the control panel to add hardware - this message was
generated when I clicked the MTS Input button.
So, I installed asio4all V2.10 thinking it might be a driver problem. After this install, the
MTS error stopped. The Input dialog now shows the channel order. MTS reports no errors.
The USB Interface is an Alesis IO2 Express. I'm running Win XP on an Acer laptop. I mention
that because the ASIO site says Asio4all v 2.10 has a workaround for a full-duplex issue with
Acer laptops and the Realtek HD drivers that are installed on my machine.
My synth is a Roland xp-50 that works well with my old usb midi cables. The only reason for
using the USB audio interface is to record xp-50 voices (driven by MTS midi) into MTS audio
files for mix-down.
Thanks for your help.
