OAT A
STORAGE
The playback head azimuth of the tape recorder may be out of
alignment. This wil
only affect recordings made on other tape
reorders. A minor head adjustment may be
required.
There Is a bad spot (dropout) on the tape.
The tape heads are dirt. Clean and degauss the tape heads
, and clean the tape cap-
stan and pinch roller.
Sometimes tape errors are caused by poor reordings. Use a
LINE or AUX input If
available. MIC inputs seem to work better if the DX "
TO INPUT" signal is attenuated
approximately 10-2Odb before recording. Many consumer electronics companies sell
cables with built-
in attenuators.
Hints
The cassette interface can be very
ustratjng
at first. Some trial and error is usually
required to get the cassette interface to read data reliably with a particular tape deck.
But once you get your recorder to work
, the interfce is very
reliable. Exp
eriment with
the recording or playback levels
, tone controls
, and type of tape. Some users like to
use computer grade cassettes beause of their lack at dropouts. Others prefer high
bias (CR02) tapes because of their extra high frequency response. Once you have
arrived at the proper settings for the controls. you may want to mark them to ease
future use.
The DX is designed to work with data recorders and profesional walkman-type
recorders as well as standard home cassette decks.
One cassette recorder that is used at Oberheim is the Superscope C-
200 LP. This
recorder seems to work well and does not invert the
catte
data.
MIDI DATA TRANSFER
The OX can also transfer its memory via MIDI. This is especially useful for sending
data from one OX to another
, or to a MIDI storage device.
Connection
The only connection required is a MIDI cable from the MIDI OUT at the source unit to
the MIDI IN of the destination unit.
Access
Enable DATA STORAGE with the switch on the rear panel. The display wil read
CASS:' Both source and destination units must be in Data StoraQe Mode to transfer
data.
..
REMEMBER: The DX will not receive a data
trnsfer
its MEMORY PROTECT
switch on the rear panel is ON.
Sending All Sequences
To send all of the sequences
, press MIDI SEND ALL. The ALL button will light during
the data transter. If a DX is used as the destination unit
, its ALL button will light as well.
When the data has finished the light will go out and the display will once again read
CASS:'
Sending One Sequence Or Song
To send a single Sequence or Song, press MIDI SEND ONE. The left side of the dis-
play wil show the sequence to transterred from the DX. Select the desired sequence
(or Song, by pressing the SOng button), then
pres ONE
again. The right side of the
display will show the location that the sequence will be transferred to. Select the
desired destination
. then press ONE again. The ONE light will be on while the data
transfer is taking place (short time). The light then will go out and the display will again
read "
CASS:' .
BATTERY BACKUP
The OX contains a lihium battery that maintains power to the memory even when the
OX is unplugged. This way you can turn off the
poer and
not lose your sequences.
With normal use, battery should last 5 years before needing replacement. However
you should always save important sequences via Cassette or MIDI
, using the Data
Storage function of the DX.
