If none of these items applies the MIDI IN socket remains unconnected.
Note that if extremely large Sys-Ex dumps are passed through the Pocket Dial then it is advisable not to
move any Pocket Dial knobs whilst this transmission is taking place, as the merge abilities of the Pocket
Dial were not intended to work whilst this kind of intense transmission is taking place.
If multiple Pocket devices (Pocket Dial/Control/Fader) are being used then the MIDI connections can be
chained together so that all the Pocket devices produce one composite data from the last MIDI out in the
chain.
Operation
Power On
The Pocket Dial is switched ON by plugging the AC adapter into a wall outlet and connecting the DC
output cable of the adapter to the appropriate jack on the rear panel of Pocket Dial. There is no separate
ON/OFF switch.
After power on the four LED's at the upper left side light up one
after another ("running light"). Then the first LED turns on indicating
that bank #1 is selected. If this does not take place the power
supply used is defective, unsuitable or has the wrong polarity.
After power on the 4 presets defined by the DIP switch setting are
transferred into the four bank memories, the MIDI master channel
and the Thru mode options are called up from the non-volatile
memory.
LED Display
Under normal operation the LEDs indicates MIDI in activity, and also MIDI out activity when moving
the knobs on the Pocket Dial. Thus the LEDs can be used to check the basic functions of Pocket Dial,
i.e. to test if actually MIDI data are received or transmitted.
The LED's are also used to display certain conditions:
•
Which of the four banks is selected and consequently - .
•
Which of the four buttons can be used to call-up a snapshot (i.e. transmit the 16 absolute values
corresponding to the 16 controls, works only if absolute MIDI data are transmitted)
•
Master channel mode for adjusting the MIDI master channel of Pocket Dial
•
Program change mode for transmitting program change messages with control #8
•
Storage mode for storing the present absolute values of the 16 controls non-volatile in the memory
•
MIDI In error
Details about these subjects follow in the next chapter "Functions of the buttons".
