MIDI configuration software such as OMS
(Open Music System) and FMS (FreeMIDI Sys-
tem) are commonly used to facilitate use of
third party controllers such as HUI. Therefore,
it’s important to make sure that HUI is defined
as a controller device in your OMS or FMS soft-
ware, and also as a controller in the DAW
environment.
First, answer the following OMS/FMS-re-
lated questions before pressing the
PANIC
button (not included on HUI):
• Is AppleTalk off? The computer uses
AppleTalk to operate through its printer
port; AppleTalk can block MIDI transmis-
sion.
• Does OMS/FMS “see” the MIDI interface?
• Is the interface speed set the same in both
the OMS/FMS setup and the hardware inter-
face? MIDI won’t transfer information if the
interface is set to one speed and the soft-
ware is set to another.
• If you have multiple setups, is the setup
document being used the most current one
(or recommended)?
• Are the MIDI instruments connected to the
appropriate port?
• Are all MIDI connections made properly?
(See page 20 for connection diagram.)
• Are your MIDI cables OK?
Many MIDI interface boxes provide indica-
tors to let you know when MIDI data is being
sent and received. If HUI passes the MIDI test
in it’s self-test routine (see page 7), any MIDI
communication problem must lie elsewhere.
Touch one of HUI’s faders and move it a little.
Does the MIDI interface “receive” indicator
light? If it doesn’t, check or replace the MIDI
cable between HUI’s MIDI OUT jack and the
MIDI interface’s IN jack.
Now move one of the faders in the DAW
software. Does the MIDI interface “transmit”
indicator light? If not, check or replace the
MIDI cable between the computer and the
MIDI interface “To Computer” connector.
• Is the device information configured properly?
• Is the correct MIDI channel defined to the
proper MIDI port? (HUI operates on MIDI
channel 1.)
• Is your MIDI interface working properly?
Is it connected to the correct port on your
computer?
• Ummm, is the MIDI interface turned on?
SERVICE
Service for HUIs bought and residing in the
United States is available only Mackie Designs.
(Do not contact Digidesign.) HUI owners out-
side the U.S. should consult their local Mackie
dealer or distributor for service.
Now then, please follow these instructions:
1. Review the Troubleshooting section of
this reference guide (pages 25-26). Assuming
you’ve done so, and used up your voluminous
reserves of common sense…
2. Have your HUI serial number ready —
hopefully you copied it down in the front of this
manual (page 3).
3. Call Mackie Tech Support at 800-258-6883
(8 AM to 5 PM, Pacific Time) to explain the
problem. If it can’t be solved over the phone
you will be issued an RA (Return Authoriza-
tion) number.
You must have an RA number
before you can obtain service from the factory.
4. Set aside the power cord, reference guide,
and anything else you want to keep. This may
or may not include half-eaten sandwiches and
large sums of money. Mackie will only send
back your HUI.
5. Pack the HUI in the original box, with the
original foam innards or other packing materi-
als. You DID save that stuff, didn’t you? If you
didn’t, you’ll need to purchase a new box and
packing materials from Mackie.
Mackie is not
responsible for any damage resulting from ship-
ments of product in “non-original” packaging.
6. Include a legible note stating your name,
return shipping address (no P.O. boxes of
course), daytime phone number, the RA num-
ber, and a detailed description of the problem,
including how we can duplicate it.
7. Write the RA number in
huge letters
on top of the box.
8. Ship the HUI to Mackie. We recommend
UPS (United Parcel Service), and suggest you
get insurance on the package. Send HUI to this
address:
Mackie Designs Inc.
Service Department
16220 Wood-Red Rd. NE
Woodinville, WA 98072
9. When we’re finished taking care of HUI,
we’ll try to send it back to you within three
business days. Ask Tech Support for current
turnaround times when you call for your RA
number. We normally send packages via UPS
Blue (second-day air). But, if you rush your
HUI to us via air mail, we’ll do the same for the
return trip. This does not necessarily apply to
non-warranty service.
