opcode studio 4 ユーザーズマニュアル

If you’re using only one serial cable 
between the Macintosh and the 
Studio 4, try using two. Use the Net-
work Routing window in the 
Studio 4 menu to route timecode 
into one port and all other MIDI data 
into the other.

Make sure the power cord is firmly 
inserted into its connector, the power 
switch is on, and that the SMPTE/Power 
indicator light is lit.

Check all the cables between your com-
puter and the Studio 4, and between the 
Studio 4 and your tape deck.

Verify that the SMPTE/Power indicator 
light blinks when it is receiving timecode 
from the tape deck. If not, you may have a 
bad cable or connection between the 
Studio 4 and your tape deck. Also, your 
SMPTE level may be recorded too low. If 
so, you may need to use a preamp or 
mixer to boost the SMPTE level before 
sending it to the Studio 4. See Chapter 10 
for proper SMPTE record levels.

Choose SMPTE Reader from the 
Studio 4 menu, then start the tape. If it 
displays timecode correctly, the problem 
is with your application setup, not the 
Studio 4.

The Routing, Channelizing and Muting 
window, OMS patches, and MIDI applica-
tions (such as sequencers) all control 
MIDI routing. Most likely, two or more of 
these settings may be routing the input to 
different devices.

If the above isn’t the cause, then...

•

you may be using an OMS patch that 
contains a splitter routed to more 
than one device on the same MIDI 
channel.

•

you may be using an OMS patch that 
references a Virtual Instrument con-
taining a splitter routed to more than 
one device on the same MIDI 
channel.

•

you may have one input routed to 
more than one output in the Routing, 
Channelizing and Muting window.

When you use the Studio 4 with non-OMS 
MIDI applications, you must enable input 
devices in the Network Routing window’s 
Input Compatibility column. See 
Chapter 6 for more information.

The Studio 4 does not work with Sound 
Designer II and samplers (such as E-mu’s
