1. IMPORTANT NOTES OB5 1.1 NOTES ON THE OB5 LOOKING AFTER THE PRODUCT • Do not apply excessive force to the structures and controls (knobs, switches, etc.). • Protect the instrument from heavy stresses during both transport and use. The instrument should only be transported in its original packaging or an equivalent. • Do not place the OB5 close to heat sources, in damp or dusty places, or close to strong magnetic fields.
hazardous signal peaks. 1.2 NOTES ABOUT THE MANUAL • Take good care of this manual. • Read all the information provided in this manual carefully. You will avoid wasting time and will obtain the best performance from your instrument. • Codes or numbers in square brackets ([]) indicate the names of buttons, sliders or trimmers on the instrument panel. For example, the word [REVERB] indicates the REVERB trimmer.
2. CONTROLS AND CONNECTORS OB5 2.1 THE TOP PANEL 1. PRESET DRAWBARS UPPER – LOWER & BASS section. This section contains the buttons for selection of the six PRESETS relating to the timbre of the UPPER, LOWER and BASS manuals (the BASS is the section of the lower manual assigned to the bass, or to the optional pedalboard if this is connected to the rear PEDALBOARD connector), and for manual operation of the Drawbars. 2. VIBRATO & CHORUS section.
2.2 THE PANELS ON THE LEFT OF THE MANUALS 1. [HOLD] button. This switch enables the display HOLD function. When this function is disabled, the display continues to show a given video page for a time of about 10 seconds after the last operation carried out, after which it again displays the main video page. With the HOLD function enabled, each video page displayed remains on the screen until the page is changed. The [DISPLAY MODE] LED illuminates to show that the HOLD mode is activated. 2. [MAIN] button.
Vibrato effects, and display of the pages it contains. 10. [UTILITY] button. Pressing this button gives access to the menu of system utilities such as setting of the MIDI functions, instrument tuning, assignment of functions to the footswitch pedals and adjustment of the display contrast. As for the other menus, this button can be used to display the pages within the Utility section. 11. [MEMORY] button.
2.3 THE REAR PANEL 1. [PEDALBOARD] connector. This connector allows connection of the optional pedalboard. 2. PEDAL [FOOTSW. I], [FOOTSW. II] and [EXPR.] jacks. Two normally open footswitch pedals, to which a function can be assigned using the system Utilities, can be connected to the [FOOTSW. I] and [FOOTSW. II] jacks, while the [EXPR.] jack can be used to connect an expression pedal for control of the organ’s overall volume. 3. MIDI [IN], [OUT] and [THRU] jacks.
3. CONNECTING AND SWITCHING ON THE OB5 3.
1. Before making any connection, make sure that the OB5 and the rest of the equipment are switched off. 2. Then connect the OB5 to the electricity supply socket by means of the power supply lead supplied with the instrument. 3.2 SWITCHING ON THE OB5 1. Before switching on the OB5, make sure that the organ volume is at the minimum setting. 2. Press the [POWER] switch on the front panel of the instrument. 3. Switch on the amplification system and the rest of the instruments connected to the OB5. 4.
When carrying out operations by means of the display, you can use the HOLD function, allowing you to “freeze” the video page displayed at that time until another page is selected, so that the display will not return to showing MAIN after a time of 7-8 sec., as already described in the “Panels on the left of the manuals - [Hold] button” section on page 48. 3.4 SWITCHING OFF When you decide to stop playing and switch off the instrument, follow these simple rules: 1.
4. FUNCTIONS RELATING TO THE SOUND OB5 4.1 WHAT PRESETS AND MEMORIES ARE As we have already mentioned, with regard to the controls on the instrument’s panels, the OB5 has two types of memories: PRESETS and MEMORIES. We will now take a look at the differences between them.
4.3 HOW TO SELECT A MEMORY In contrast with the Presets, a given Memory can only be recalled by means of the display. From the MAIN video page: press the [MEMORY] button; the last memory selected will be activated and the display will show: Alongside the Vol (Volume) parameter, indicating the overall volume of the organ, the screen now shows the Mem. (Memory) parameter, informing you of the number of the memory activated.
informing you that the OB5 is initialising the Presets. On conclusion of the operation, the display will show the MAIN video page. N.B.: When a Preset Factory Settings operation is carried out, the setups saved by the user will be lost irretrievably. To avoid this, save the chosen Presets in specific Memories, and if a Memory Factory Settings operation is to be performed (see next section), carry out a Bulk Dump (see section 7.2) of the Memories concerned. 4.
If you wish to abort the Memory saving operation, press [EXIT] from the previous video page. If you wish to restore the original contents of one or all the memories, locate the cursor on the [Memory INIT] field and press the [ENTER] button. The display will change to: The Memory INIT field displays the memory location on which the Factory Settings operation will be carried out if the [ENTER] button is pressed. You can use the [-/NO] and [+/YES] switches to scroll through all 50 Memories.
Pressing [ENTER] again completes the procedure; pressing [EXIT] aborts it. If the initialisation procedure has been confirmed, on its completion the display will show: confirming that the Factory Settings of all the Memories have been restored. 4.6 CREATING THE SOUND WITH THE DRAWBARS The harmonic bars or Drawbars allow you to set the basic character of the sound you are going to use in your performance. When a Drawbar is pushed right into the organ (i.e.
The Drawbars can also be pressed in or pulled out while you are playing, giving real time control of the timbre and creation of the most widely varying sounds. To play with the real Drawbar positions (i.e. not with the Preset settings) press the [UPPER] and/or [LOWER&BASS] buttons of the PRESET DRAWBARS section.
For activating the percussion, there are two buttons in the PERCUSSION section of the front panel called [2nd] and [3rd]. The [2nd] button activates the second harmonic percussion (the octave of the 8’ Drawbar), while the [3rd] adds the third harmonic percussion (the octave and fifth of the 8’ Drawbar, i.e. the twelfth). N.B.: The [2nd] and [3rd] buttons are mutually exclusive, so the two types of percussion cannot be used simultaneously.
With the Perc. Level parameter you can adjust the level attenuation of the percussion, while Perc. Length sets the decay time rescaling. Obviusly these parameters are strictly correlated with the fuctions enabled by the buttons [SOFT] and [DECAY] located on the upper panel. The TopKey parameter indicates the highest note in the keyboard range on which the percussion is to apply, while DrawbVolAtt (Drawbars Volume Attenuation) allows you to reduce (Yes) the volume of the sound produced by the Drawbars.
In this video page, you can regulate the operating mode of the bass section. The BassMode parameter allows you to play the bass, in monophonic mode, on the lower manual together with the LOWER manual Drawbars, by setting it as Layer. If this parameter is changed to Replace the bass will be played with the BASS section Drawbars only, in polyphonic mode. Finally, if Pedal is selected the BASS section will be played with the optional pedalboard, in polyphonic mode.
The OB5 is able to provide a detailed reproduction of these features of the original organs; at the time, efforts were made to eliminate them, but today they are part of the typical sound of an electromagnetic organ.
5. THE EFFECTS SECTION OB5 5.1 VIBRATO & CHORUS The VIBRATO & CHORUS section of the front panel allows Vibrato and Chorus effects to be added to the OB5’s sound. Vibrato modulates the tuning of the signal in cyclic mode, while the Chorus is the sum of the direct and modulated sound (so that the amplitude of the signal is also modulated).
highest speed in the range available to the modulant of effect V2. 5.2 REVERB Reverb originates from the sum of the various acoustic reflections produced by a sound in a natural environment. When we clap our hands inside a large reflective building like a church, for example, we will hear a strong resonance which gradually fades. The OB5 Reverb effect emulates this way in which sound resonates inside an enclosed environment.
The parameter sets the time interval between one repetition and the next, while Reg (Regeneration) sets the amount of signal which will be reprocessed with the Delay algorithm, and thus the time after which the repetitions die away. Time 5.3 ROTARY The OB5’s ROTARY algorithm simulates the archetypal effect produced by a rotary tone cabinet connected to the organ.
The original electromagnetic organs were equipped with an internal spring reverb system, so the signal amplified by the rotary tone cabinet was already complete with reverb. By means of the parameter described above, the OB-5 allows emulation of this feature (if the parameter is set as Rev~Rot), or selection of a setup in which the signal obtains its reverb from the environment, after it has been emitted by the rotary tone cabinet (if the parameter is set as Rot~Rev).
6. USING A REMOTE ROTARY TONE CABINET OB5 The OB5 allows you to connect a real rotary tone cabinet to the 11-pin rear jack [ROTARY TONE CABINET], as an alternative to the internal ROTARY effect. Thanks to its rotary speakers, this type of cabinet produces a very complex combination of vibrato and tremolo, which changes with every harmonic and every note of the scale. When a remote rotary tone cabinet is used, the internal Rotary effect will be disabled automatically.
N.B.: PIN 11 senses connection of a connector to the ROTARY TONE CABINET jack. If the voltage is not inside a range from 18 to 30 V DC, the tone cabinet might not work correctly. Moreover, sudden current surges might cause malfunctions or breakdowns of the OB5 or of the tone cabinet. You can use the [ROTARY ON/OFF] switch on the panel on the left of the manuals to switch the cabinet motor on or off, while the [ROTARY SLOW/FAST] is used to select the rotation speed (fast/slow) of the tone cabinet motor. 7.
The same type of transfer of information is used to record MIDI sequences. A sequencer can be used to record the MIDI data transmitted by the OB5 or any other instrument. When these recorded data are sent to the OB5, it will automatically play back the recorded performance. CAUTION! Always use top quality cables for the MIDI connections from and to the OB5. We also advise the use of cables no more than 5 metres long.
• Control Change: these are control messages (often associated to sliders or pedals) used to add expression to the performance, by allowing definition (and real-time control) of the timbre parameters, such as the volume (CC n.7) or the amount of reverb (CC n.66), etc. As already mentioned, the system messages are independent of the subdivision of the channels, and once processed, they take effect on the entire system.
which relates to the reception channels for the message arriving on the MIDI IN port. Since this video page is identical to the previous one (setting of the channels for the transmission of MIDI messages), refer to the information above for the parameters found in this video page. When the [UTILITY] button is pressed to move on to the next video page, the display will show: In this page, the user can enable or disable the filters for transmission of MIDI messages.
Pressing [UTILITY] again allows you to display the next MIDI function programming page: This video page allows you to set the Bulk Dump function. As we have seen in the introductory notes about the MIDI, the Bulk Dump makes it possible to send all the OB5’s internal programming to a sequencer or computer (for example, in order to save the contents of the memories, and avoid the risk of losing data).
If for example you have set the tuning as indicated in the display shown above, the result will be as follows: This is what is played: ...this is what is heard. N.B.: when the SEMITONES parameter is altered, the result will not be audible until any keyboard key or keys pressed during the operation are released. 7.
Let us take a detailed look at how a function is assigned. Select the [PEDAL ASSIGN] field and press [UTILITY]; the display will show: The video page contains two fields, Pedal1 and Pedal2, representing the footswitch pedals connected to the [FOOTSW.1] and [FOOTSW.2] pedal jacks respectively. The functions which can be assigned are the following: • Rotary On: • RotaryS/F Activation of the Rotary effect (internal or remote) and switch-on of the motor of a rotary tone cabinet, if connected.
The video page consists of two fields, Upper which identifies the sequence of Presets relating to the upper manual, and Low&Bass which displays the sequence of Presets for the lower manual and the BASS section (or the optional pedalboard). The CURSOR keys [ï] and [ð] can be used to select one of the seven steps in the sequence you wish to program, while the VALUE keys [-/NO] and [+/YES] allow you to scroll through the seven Presets and set the one you require in the step you are editing.
8. USING THE MIDI OB5 8.1 PARAMETERS CONTROLLABLE BY MEANS OF CONTROL CHANGES 1) Volume (CC 07): regulation of the general volume of the organ and of the LOWER manual volume. Control Change #07 can be used to control the general volume of the organ or of the individual sections, by means of another instrument connected by MIDI (such as a Sequencer, Master Keyboard, etc...). The Control Change acts in a proportional manner, i.e. high MIDI parameter values produce larger amounts of volume.
Depending on whether the active effect is a reverb or the Delay, Control Change #103 controls the value of the cut-off frequency of a low-pass filter capable of attenuating all frequencies above the one set (for the reverbs) or the number of repetitions (for the Delay). The higher the value of the Control Change concerned, the higher the cut-off frequency (for the reverbs) or the greater the number of repetitions (for the Delay). 9) Vibrato Speed (CC 76): modulation speed of the Vibrato and Chorus effects.
8.2 PARAMETERS CONTROLLABLE BY MEANS OF EXCLUSIVE SYSTEM Exclusive system messages received by the OB-5 must have the following format: String: Byte n.: F0 31 3n dd vv cc xx yy F7 1 2 3 4 5 6 7 8 9 where: 1- Excl.
