This manual is a quite accurate copy of the original manual. A guy from Waldorf was so kind to send it to me before Waldorf left the market. I scanned, OCR´d and worked it over. I tried to reproduce everything as original as possible. I only corrected some minor mistakes in writing, left out the blank pages and so on.
1. General 1. General Warranty Waldorf Electronics warrants the MIDI BAY for a period of 6 months. This applies solely to flaws in material. Any claims can be made within this period only.

5. How It Works 5. How It Works How It Works If you own several MIDI devices - probably some of them sending and receiving data on several MIDI channels - you're probably vexed regularly because the connection cables have to be rearranged all the time: when controlling several sound expanders from one keyboard, you would like to control the same expanders by the sequencer and play along on a second...

5. How It Works 5. How It Works The MIDI specification determines that one MIDI OUT is assigned to each MIDI IN. However, if you want to transmit one MIDI signal to several instruments, there are exactly two ways to do so: either you connect these instruments to each other via their MIDI THRU connectors (already with three units this might lead to signal delay and...

5. How It Works 5. How It Works The MIDI BAY integrates both functions - copying and merging MIDI signals - and additionally offers the possibility of programming any "set" of inputs and outputs, and of selecting them at the touch of a key or with a MIDI instruction, at any time.
6. Controls 6. Controls Controls The MIDI BAY features the following controls and female connectors: The upper portion of the front panel is reserved for the assignment list. The two notches on the plexiglass frame serve for pulling out the assignment list. Entering the connected units in that list will facilitate setting up of MIDI BAY programs.
Page 10
6. Controls 6. Controls The front panel of the MIDI BAY also accomodates four connectors: <MIDI Aux.> offers two MIDI connectors that are identical to the connectors [Source 15] and [Destination 15] on the rear. The MIDI IN connector on the front has priority: as soon as you hook up a MIDI instrument here, the corresponding MIDI IN connector on the rear is switched off.
7. Installation 7. Installation Installation set up the MIDI BAY at a place where it is not ● exposed to strong vibrations, dust or extreme humidity. Connect the unit to the mains. the MIDI BAY may also be installed within a 19" ➔...
8. Operation Modes 8. Operation Modes Operation Modes The MIDI BAY places seven different operation modes, or function levels, at your disposal. Switch over between the individual modes using the [Mode] key. At each key press the unit changes to the level "next in rank". the selected operation modes after each key press ●...

8. Operation Modes 8. Operation Modes In Channel Mode, the MIDI channel on which the MIDI BAY receives program change instructions can be adjusted. Activate the DUMP Mode to send the MIDI BAY's entire memory contents (the 99 programs) via MIDI - at the simple touch of a button.
9. Creating Programs 9. Creating Programs Creating and Editing Programs switch on the MIDI BAY. ● Now the unit is in PLAY Mode: the display indicates the number of the selected program memory location, the green "Play Mode" LED is lit. using the [Up] and [Down] keys, select the program ●...

9. Creating Programs 9. Creating Programs However, it will be most useful to program a simple standard configuration before. select memory location #1 - as described above - ● and activate the EDIT Mode. The display changes from When using this kind of representation, the right display half shows the selected [Destination] connector and the left display half the assigned [Source] connector.
Page 16
9. Creating Programs 9. Creating Programs all changes are accepted immediately. So you can ➔ check - while running the sequencer or playing on your master keyboard - whether the desired connection has actually been established. Of course, you should also observe that both sending and receiving units are set to the same MIDI channel.
9.1 The Merge Function 9.1 The Merge Function The Merge Function As you have already noticed, you may not only send MIDI data package several connectors simultaneously, but you may also combine two data packages and subsequently send them to one or several outputs.
Page 18
9.1 The Merge Function 9.1 The Merge Function using the [Down] key. select connector [Source 5]. ● Thus, [Source 5] is defined as second merger input. Now, you just have to determine to which [Destination] connector(s) the data shall be routed. Proceed as follows: using the [Up] key, select connector [Destination 3].
Page 19
9.1 The Merge Function 9.1 The Merge Function coming from any two [Sources], simply change this connector's assignment. The only disadvantage of this procedure is that now you only have 14 inputs and outputs at your disposal. Another example to clarify the facts: connect [Destination 15] to [Source 1] via a short ●...

9.2 The Merge Filter 9.2 The Merge Filter The Merge Filter Merging MIDI signals leads to specific problems, above all if "system overlapping" messages are concerned. For instance. ROLAND keyboards send the MIDI message "All Notes Off" as soon as all keys are released, which switches off all notes played.
Page 22
9.2 The Merge Filter 9.2 The Merge Filter The following types of data may be filtered out: <cM> Channel Mode Messages are special controller messages and are used to set MIDI instruments to certain operation modes. Furthermore, they mute all voices sounding at the moment. To avoid unpleasant results - described at the beginning of this section - they should be filtered out.
Page 23
9.2 The Merge Filter 9.2 The Merge Filter switch off the Running Status for the merger output. Simply depress the [Up] key. Having effected all settings as desired, you may return to the Play Mode by depressing the [Mode] key. However, if you do not want to store the changes you made, leave the Merge Filter Mode by hitting the [Panic] key.
10. Selecting Programs 10. Selecting Programs Selecting Programs There are three ways to switch over between the programs of the MIDI BAY. The unit must always be in PLAY Mode. Changing programs on the unit: use the [Up] and [Down] keys to select a MIDI BAY program.

10. Selecting Programs 10. Selecting Programs please note that when changing the configuration ➔ while playing, you might also change the assignment of a certain [Destination] connector, even if notes are still played. To avoid hanging notes, an "All Notes Off"...
11. The Panic Key 11. The Panic Key The PANIC Key Hanging notes are not as usual as you would suppose when reading relevant articles, leaflets and brochures, however, if they occur they are always good for a large- scale panic. There are two reasons for hanging notes: due to a (mechanical) interruption of the MIDI connection while some notes are still on, or due to a certain instrument...

12. Copying Programs 12. Copying Programs Copying Programs Every now and then, you might wish to copy a MIDI BAY program from one memory location to another. Especially, if you need an already existing program a second time, in a slightly changed version, this function will be very useful.
13. The Dump Function 13. The Dump Function The Dump Function Like any other advanced MIDI device, the MIDI BAY offers the possibility of transmitting your program data as a so-called Sys Ex Dump via MIDI, of course, Sys Ex data may also be received.
13.1 Changing The Unit ID 13.1 Changing The Unit ID Changing the Unit ID If you own a VERY extensive MIDI system you might also have two or even more MIDI BAYs. In this case, it will also be possible to send Sys Ex data to one of these MIDI BAYs only.
14. Assignment List 14. Assignment List This list will be your note-pad when creating and using MIDI BAY programs. Enter the units and instruments used and draw the programmed connections by hand or with a ruler. Program: __________________ Date: _____________ Instrument Instrument (merge in 1)
