8.4 MIDI connections
The MIDI standard (Musical Instruments Digital Interface) was
first developed at the beginning of the ’80s, with the goal of
enabling mutual communication between electronic instruments
of various manufacturers. Over the years, the number of possible
MIDI applications has increased substantially; nowadays, it is
perfectly normal to connect entire studios via MIDI.
At the center of this network is a computer with a sequencing
software, used to control not only keyboards but also effects
processors and other peripheral equipment. In such a studio,
you can control your BASS V-AMP/BASS V-AMP PRO in real
time from a computer. Using a MIDI footswitch presents itself as
a great idea, especially in live applications, because it allows
you to control not only the effects but also selects the presets.
Your BASS V-AMP/BASS V-AMP PRO is equipped with
standard 5-prong DIN MIDI connectors. To connect your unit
with other MIDI equippment, you will need a MIDI cable. Pre-
packed cables available at stores are usually used for this
purpose.
MIDI IN: Used to receive MIDI control data. The MIDI channel is
set up in EDIT mode by pressing the A key and subsequently
using the arrow keys.
MIDI OUT/THRU: MIDI OUT lets you send data to another
computer or another piece of MIDI equipment. Preset data as
well as parameter changes are transmited. When you reroute
the connector to MIDI THRU, your BASS V-AMP/BASS V-AMP
PRO sends no MIDI data of its own; instead, it merely forwards
the data received at MIDI IN (see chapter 2.1, A).
8.4.1 Receiving/sending MIDI-Sysex data
The BASS V-AMP/BASS V-AMP PRO can receive a SysEx
dump from another MIDI unit as long as MIDI function in EDIT mode
is activated (A key). However, this also automatically overwrites
all BASS V-AMP/BASS V-AMP PRO presets. You can also send
MIDI data to another MIDI device (total dump). While in EDIT mode,
keep the MIDI key pressed until you get “d” shown in the display.
Sending a “total dump“ lets you transfer the entire memory
contents to another MIDI sequencer and save it there.
It is also possible to send just one selected preset to another
MIDI device: switch into EDIT mode by simultaneously pressing
both arrow keys on the sending device, activate the MIDI function
and tap the MIDI key briefly. Preset information are then located
in the temporary buffer, and can be saved at a desired preset
location.
8.5 AES/EBU and S/PDIF standards
In general, there are two different standards when the subject
is digital signal processing. AES/EBU is the professional, balanced
connection with XLR jack connectors. This interface is based on
two identical protocols published in November 1985 by the
European Broadcast Union (EBU Tech. 3250-E) and in December
1985 by the Audio Engineering Society (AES3-1985). Sony and
Philips oriented themselves around this standard and developed
an additional interface with unbalanced signal routing and several
important differences that primarily have to do with allocating
channel status bits. This standard, named after the two com-
panies (S/PDIF = Sony/Philips Digital Interface) uses either cinch
jacks or a digital connection with optical cables. It is relevant
mostly because of the attempt to introduce copy protection
embedded in the IEC 958 norm. This norm describes both the
re-worked AES/EBU interface that has been modified to work
with the S/PDIF format and described as IEC 958 Typ I
(Professional). The formal description of the S/PDIF interface is
IEC 958 Typ II (Consumer).
