opcode studio 4 Manual Do Utilizador

From the MIDI Format pop-up menu, 
choose the MIDI sync format your soft-
ware uses. This pop-up menu duplicates 
the Format pop-up menu found in the 
SMPTE Reader window. The Studio 4 
converts SMPTE timecode into the MIDI 
format set in this pop-up menu. The 
choices are:

•

No Sync: The Studio 4 ignores the 
SMPTE input signal. Also, it doesn't 
show timecode when striping.

•

MTC: The Macintosh uses MIDI 
Time Code to read the value of the 
SMPTE signal.

•

DTL: The Macintosh uses Direct 
Time Lock to read the value of the 
SMPTE signal.

•

DTLe: The Macintosh uses 
Enhanced Direct Time Lock to read 
the value of the SMPTE signal.

The pop-up Level menu lists eight set-
tings for the SMPTE output level. Choose 
one that provides the best input signal for 
your particular tape recorder. The follow-
ing guide covers the optimum input levels 
for various types of machines. Adjust the 
Level command to give a SMPTE input 
value closest to the following.

•

If your tape machine operates at -10 
dB, adjust the SMPTE output level for 
a tape input of about -3 dB.

•

If your tape machine operates at +4 
dB, adjust the SMPTE output level for 
a tape input of about -7dB.

•

If you are using a -10 dB machine 
with LED metering, adjust the 
SMPTE output level for a tape input 
between -1 and -2 dB.

•

If your audio recorder uses dbx noise 
reduction and you can’t defeat it, 
adjust the SMPTE output level for a 
tape input between -1 and 0 dB.

•

If you have a mixer in the SMPTE 
signal path (and you shouldn’t), make 
sure that the equalization is either 
switched out or flat. Any filtering of 
the SMPTE signal will render it 
invalid.

The Studio 4 has a Jam Sync mode. In this 
mode, it generates a fresh SMPTE signal 
from the SMPTE OUT jack in sync with 
the signal received at the SMPTE IN jack. 
You should always use Jam Sync mode to 
regenerate a SMPTE track when you 
copy tapes; a copied SMPTE track may 
degrade enough to make it unusable.
