PULSE WIDTH - adjust the pulse width of the oscillator (when in pulse mode) from narrow, to square (center position), to wide.
SHAPE - select the waveform of the oscillator from pulse or reverse sawtooth.
OSC MOD - select the depth of modulation applied to the oscillator. (5) MOD SOURCE - select the modulation source from the envelope (or an external modulation source), or the LFO.
MIX - adjust the mix between the VCO output and the internal noise generator. If an external audio input is used, then this is added to the mix, instead of the noise.
MOD DEST - select the modulation destination from pulse width modulation, or frequency modulation.

Filter (VCF) Section

CUTOFF - adjust the cutoff frequency of the filter.
MODE - select the VCF filter from low-pass or high-pass.
RESONANCE - adjust the amount of enhancement given to the signals at the cutoff frequency.
MOD SOURCE - select the modulation source of the VCF from the envelope generator or the LFO
VCF MOD - adjust the depth of VCF modulation.
MOD POLARITY- select the polarity of the VCF modulation.

Output (VCA) Section

VOLUME - adjust the overall synthesizer output level.
VCA MODE - select envelope, and the VCA is modulated by the envelope. In the ON position, the VCA output is the last key played, and is independent of envelope.

Envelope Section

ATTACK - control the amount of time taken to reach the maximum level after a key is pressed.
DECAY - control the amount of time taken to decay from the current level to minimum.
SUSTAIN - control the level of the envelope that is sustained after the attack time has been reached.
SUSTAIN ON/OFF - in the OFF position, the level will start to decay after the attack time is over. In the ON position, the sustain level will be held for as long as the key is held.

Modulation Section

LFO RATE - adjust the frequency of the low frequency oscillator. The LED will flash at the LFO rate.
SHAPE - select the LFO waveform from squarewave or triangular wave.

Utility Section

GLIDE - adjust the amount of Glide time (Portamento), between notes on the keyboard. (If SHIFT is held, then the knob also adjusts the "ratchet" during sequencer operation.)
VC MIX - adjust the VC MIX from LO/Mix 1 to HI/Mix 2. This control requires patch cords to operate, as it is outside of the internal sythesizer signal path.

Sequencer Section

TEMPO/GATE LENGTH - this knob controls the sequencer tempo. During step editing, it also controls the GATE length. If SHIFT is held, then the knob also adjusts the SWING.
HOLD/REST - during pattern playback, this allows you to hold the current step. During step editing, it allows you to enter a rest. During ARP mode, it allows you to enter/ exit ARP-Hold mode. During keyboard use, it allows you to hold the keys. (A footswitch connected to the HOLD input will also do this.)
RESET/ACCENT - during playback, this allows you to reset the pattern back to step 1. During step editing, you can add an accent to a step.
ARP (SET END) - In ARP mode, an arpeggio will play, based on the held notes using the CRAVE's 13 keyboard switches. Double-press to play and hold an Arpeggio. In Sequencer mode, pressing SHIFT and SET END together, followed by a STEP switch, will allow that step to become the end of the current pattern.
PATTERN (BANK) - This button is used to access either the current pattern, or bank number, as follows:
PATTERN: Press PATTERN, and one of the 8 LOCATION LEDs will show the current pattern number (from 1 to 8). To change to a different pattern number, keep the PATTERN button held down and press any of the STEP buttons (1 to 8), or press <KYBD to decrease, or STEP> to increase the pattern number.
BANK: Press SHIFT and PATTERN, and one of the 8 LOCATION LEDs will show the current bank number (from 1 to 8). To change to a different bank number, keep both SHIFT and BANK held down, and press any of the STEP buttons (1 to 8), or press <KYBD to decrease, or STEP> to hincrease the bank number.
OCTAVE/LOCATION - these multi-colored LEDS show various details, such as the Octave, PATTERN number, BANK number, current PAGE, and GATE LENGTH.
KEYBOARD/STEP SWITCHES - these multifunction switches allow you to view and select individual pattern steps, select a pattern number, select a pattern bank. They are used during recording of a pattern to show the current step. Active steps are illuminated with a steady red LED, and the current step flashes red. The switches are laid out as a 13-note keyboard. The octave can be moved up and down by pressing the <KYBD or STEP> switches, and the row of 8 LEDs will show the current octave. The switches are used to control the sequencer editing, as well as the arpeggiator operation.
SHIFT - this is used to access the secondary features of some of the other sequencer controls, such as SET END, BANK, SWING, KYDB, and STEP. Hold down SHIFT and the other switch at the same time. For example SHIFT + PATTERN (BANK) will show the current BANK number in the LOCATOR LEDs.
PAGE - each pattern can be up to 32 steps in length. This switch allows you to show each of the 4 pages of 8 steps each. The LOCATION LEDs 1 to 4, show which page you are on. If a pattern is playing, the STEP LEDs will show the steps in use on the current page.
PLAY/STOP - starts or stops the playback of the pattern. If SHIFT is held at the same time, then this is the start of the pattern saving procedure.
REC - press this to begin the recording of a new pattern. This is also used with SHIFT during the pattern saving procedure.
KYBD - press SHIFT + KYBD to change the sequencer to keyboard mode.
STEP - press SHIFT + STEP to change the sequencer to STEP mode.

Getting started

OVERVIEW

This 'getting started' guide will help you set up the CRAVE analog synthesizer and briefly introduce its capabilities.

CONNECTION

To connect the CRAVE to your system, please consult the connection guide earlier in this document.

SOFTWARE SETUP

The CRAVE is a USB Class Compliant MIDI device, and so no driver installation is required. The CRAVE does not require any additional drivers to work with Windows and MacOS.

HARDWARE SETUP

Make all the connections in your system. Use the rear panel MIDI switches to set the CRAVE to a unique MIDI channel in your system. Connect an external MIDI keyboard directly to the CRAVE MIDI IN 5-pin DIN type input.
Apply power to the CRAVE using the supplied power adapter only. Ensure your sound system is turned down. Turn on the CRAVE rear panel power switch.

WARM UP TIME

We recommend leaving 15 minutes or more time for the CRAVE to warm up before recording or live performance. (Longer if it has been brought in from the cold.) This will allow the precision analog circuits time to reach their normal operating temperature and tuned performance.

OSCILLATOR VCO SECTION

The CRAVE has one main voltage controlled oscillator (VCO). The VCO waveform can be selected from pulse or reversesawtooth. When pulse is selected, the pulse width can be varied from narrow, squarewave (center) to wide pulse. Listen to the changes in sound that the waveforms and the change in pulsewidth make. The frequency can be adjusted up or down one octave, and allow fine tuning to other instruments. The VCO may be modulated either in pulse width, or in frequency. The source of the modulation can either be the envelope as detailed below, or the low frequency oscillator (LFO). The VCO can also be modulated using the OSC MOD input in the patch bay.
The amount or depth of VCO modulation can be adjusted using the OSC MOD control.
Use the MIX control to adjust the mix between the internal VCO (fully left)and the internal noise generator (fully right). If an external input signal is present at the EXT AUDIO input, then this will take the place of the noise in the mix.

FILTER (VCF) SECTION

Play with the cutoff frequency, and resonance controls, and listen to their effects on the sound.
The classic 24 dB/octave high pass and low pass filters allow a great deal of control over the sounds created by CRAVE.
The high-pass filter reduces the level of signals that are below the cutoff frequency. It effectively reduces the level of the fundamental, and lower order harmonics. The low-pass filter reduces the level of signals that are above the cutoff frequency. It reduces the levels of the higher-order harmonics.
The resonance control gives an enhancement to the signals at the crossover frequency.
The amount of VCF modulation can be varied with the VCF MOD control, and also the polarity can be reversed. For example, if modulation increases the cutoff frequency, then negative polarity will decrease it.
The VCF modulation source can either be the envelope or the LFO. All these features, in addition to using the patch bay, allows for a great deal of flexibility in sound creation.

MODULATION SECTION

The low frequency oscillator can be used to modulate the VCO and the VCF. The LFO frequency can be varied, and the waveform selected from square or triangular. An LED indicates the LFO rate.

ENVELOPE GENERATOR SECTION

The envelope generator can be used to modulate the cutoff frequency in the VCF section, and the voltage controlled amplifier (VCA). Envelope also can be used to modulate the VCO frequency and pulse width.
The controls for attack time, sustain level and decay time, allow you to adjust the envelope shape through a wide range.

PATCH BAY SECTION

This section allows you the versatility to create many different sounds, with an endless variety of options and configurations.
The VC MIX control is like having a separate mini-mixer or variable voltage source. It operates independently from the main signal path. It allows you to adjust a mix between the patchbay MIX 1 input and MIX 2 input, with possible modulation control from the VC MIX CV input. The patchbay VC MIX output can then be used to connect to other inputs in the patch bay.
If there are no MIX 1 or MIX 2 inputs connected, then theVC MIX output will vary from 0V (fully left) to +5 V (fully right). Experiment with this by connecting the VC MIX output to an input, and varying the VC MIX control.

Do not overload the 3.5 mm inputs. They can only accept the correct level of voltages as shown in the specification tables. The 3.5 mm outputs should only be connected to inputs capable of receiving the output voltages. Failure to follow these instructions may damage the CRAVE or external units.

SEQUENCER SECTION

The sequencer is described in further detail in this document.
It also features an arpeggiator, and a 13-key keyboard.

OUTPUT (VCA) SECTION

Use the main volume control to adjust the sound level in your headphones or speaker system.
Keep the level down low when first putting on headphones.
Keep the CRAVE power turned off when making any connections. Turn on the CRAVE before turning on any power amplifiers, and turn it off last. This will help prevent any turn on or turn off "pops or thumps" in your speakers.
The output can be modulated using the envelope, or it can be on continuously, playing and holding the last note played, until the next note occurs.

FIRMWARE UPDATE

Please check our website behringer.com regularly for any updates to the firmware of your CRAVE synthesizer. The firmware file can be downloaded and stored on your computer, and then used to update the CRAVE. It comes with detailed instructions on the update procedure.

Sequencer operation

OVERVIEW

The following details show some of the basic operation of the sequencer. You can create a short pattern of 2 or 3 steps, before trying more complex patterns. Adjust a single parameter at a time, such as gate length, ratchet, accent, glide, rest, tie, or swing, and then listen to its effect during playback.
It will help to choose a simple setting for the synthesizer, and no modulation of the VCO or VCF.

RECORDING A SIMPLE PATTERN

Press SHIFT and <KYBD to select the keyboard mode.
Initialise the current pattern by pressing SHIFT, RESET, and PATTERN at the same time. This will delete any previous steps of the current pattern.
Press REC, and the STEP 1 switch LED will begin flashing, indicating this is the current step about to be added and edited. (If you cannot select REC, then repeat step 1.)
Press any note on the CRAVE keyboard, or a rest as shown below. The <KYBD and STEP> switches can be used to change the octave. , indicated by 8 OCTAVE / LOCATION LEDs lit red.
To enter a rest instead of a note, press the HOLD/REST switch. When a rest is added, the LOCATOR LED 8 will light.
Press further notes. The next STEP switch LED will be flashing after each note or rest has been added.
The gate length of a step can be adjusted using the TEMPO/GATE LENGTH control. The LOCATOR LEDs will turn red, showing the gate length from 1 to 8. If set to 8, this creates a tie with the next step. If the next step is the same note, this creates a longer note, as the 2 steps are tied.

To create a "Ratchet," hold SHIFT, and turn the GLIDE control. The locator LEDs will show the number of ratchets from 1 to 4, in yellow. For example, with a setting of 4, the single step is split into 4 equal parts. When a ratchet is applied, the LOCATION LED 6 will light.
To turn the GLIDE on for a step, turn up the GLIDE control. To turn off, turn it all the way down. When GLIDE is on for a step, the LOCATION LED 5 will light.
To increase the brightness or accent, press the RESET/ ACCENT switch. When an accent is applied, the LOCATION LED 7 will light.
Press REC when you have finished creating the pattern. It is not saved yet, but it can be played back. Caution: Do not turn off the unit, or create a new pattern, or the current unsaved pattern will be lost.

PLAYING A PATTERN

Press PLAY/STOP to listen to the current pattern.
If you decide not to save it, you can repeat the recording steps above to record a new pattern. Alternatively, press PATTERN and RESET to recall the currently saved pattern, and discard any changes.
If you decide to save the pattern, you must follow the "SAVING A PATTERN" procedure shown below, or it will not remain in memory if a new pattern is begun, or the power is turned off.
To create a SWING for this pattern, hold SHIFT and adjust the TEMPO/GATE LENGTH control. In the center position, no swing is applied, if turned down, only the off-beats will play, and if all the way up, only the on-beats will play. The SWING setting for the pattern is saved when the pattern is saved as shown below.

While playing a pattern, you can: Press HOLD/REST to hold the current step. Press RESET/ACCENT to return to step 1. Press SHIFT and any STEP, and you can edit the gate length, rest, accent, ratchet, glide but not note. Press SHIFT and the same STEP again to exit step edit. (If playback is paused, the same operation can edit the note as well. Press PAGE to view the pattern page from 1 to 4. Press SHIFT and PAGE to return to automatic page turning. Press SHIFT and ARP/SETEND and a STEP to change the sequence end step. PLAY/STOP to pause playback.
Press PLAY/STOP.
Note: To play in reverse, press SHIFT and PLAY/STOP.

SAVING A PATTERN

Press and hold SHIFT + PLAY/STOP for 2 seconds until the LOCATOR LED of the current pattern number begins to flash green slowly.
Press a STEP switch 1 to 8 to select the new desired pattern number.
Press PATTERN + STEP switch 1 to 8 to select the desired bank number.
Press SHIFT + REC to save the pattern and exit the save mode.

RECALLING A SAVED PATTERN

Press and hold PATTERN. The LOCATION LED will show the current pattern number. Use the <KYBD or STEP> switches to move up and down through the patterns 1 to 8, or press a STEP switch 1 to 8. You can also do this while a pattern is playing.
Press and hold SHIFT and PATTERN. The LOCATION LED will show the current bank number. Use the <KYBD or STEP> switches to move up and down through the banks 1 to 8, or press a STEP switch 1 to 8. You can also do this while a pattern is playing.
Press PLAY/STOP to play back the current pattern.
During playback, the LOCATION LEDs will show the current page of the pattern (1 to 4), and the STEP Switch LEDs will show the steps moving.

LIVE PERFORMANCE

During playback, temporary adjustments can be made as follows.
(None of these are saved with the pattern.)

To add Ratchet to all steps of the pattern, press SHIFT and adjust the GLIDE control.
To add SWING, press SHIFT and adjust the TEMPO control.
To mute the pattern, press SHIFT + HOLD/REST.
To add an accent to all steps, press SHIFT + RESET/ACCENT.
Use the <KYBD and STP> switches to change the octave. The LEDs will show the current Octave in red.

EDITING A PATTERN

To edit a pattern in Keyboard mode, press REC. The STEP switch LEDs will light.
Press PAGE to select the pattern page from 1 to 4 to be edited. The green LOCATION LEDs 1 to 4 will show the current page and the PAGE button LED lit to indicate the page is locked (press SHIFT and PAGE to unlock).
Press SHIFT and the STEP switch you want to edit. You can enter a new note, or a rest, and adjust any of the other parameters such as ratchet, glide on/off, and so on.
Press SHIFT and the next STEP switch to be edited. (The steps will not automatically advance to the next step in line; you can choose which steps to edit next.)
Press REC to exit the editing mode.
Press PLAY/STOP to listen to the edited pattern.
Remember to save the pattern using the "SAVING A PATTERN" procedure above.

CREATING A PATTERN IN STEP MODE

Press SHIFT and STEP> to select the Sequencer's STEP mode. The flashing LOCATION LED will turn from green (Keyboard mode) to yellow (Step mode).
Initialise the current pattern by pressing SHIFT, RESET, and PATTERN at the same time. This will delete any previous steps of the current pattern. (If you want to use the current pattern instead, then do not initialise it.)
Press PAGE to move to a desired page of your pattern. Then press SET END and a STEP switch to choose the length of the pattern. For example, if you are on page №1 and press SET END + 8, then the pattern length is 8 steps. If you press PAGE and reach page №4, and press SET END + 8, then the pattern will be 32 steps long (4 pages of 8 steps each).
When the desired SET END is selected, all the STEP switch LEDs up to that step will be on solid red.
Press SHIFT and any one of the STEP switches at the same time. It will begin to flash, indicating it is the current step about to be edited. You can now add a note, or a rest, or any of the other functions described above in the Keyboard mode, such as Ratchet, Glide, Accent, change gate length and so on.
Press SHIFT and the current STEP switch to finish editing that step. It will stop flashing.
Repeat procedure steps 5 and 6 above, until all your required steps are good.
Press PLAY/STOP to play the pattern.
While playing, you can add temporary adjustments as shown in the "LIVE PERFORMANCE" procedure above.

SAVING A PATTERN IN STEP MODE

Save the pattern using the "SAVING A PATTERN" procedure shown above for the KEYBOARD mode.

Do not turn off the unit, or create a new pattern, or the current unsaved pattern will be lost.

Tempo and Assign Mode Select

The tempo input and assign mode may be changed using the following procedure:

Press SHIFT+ HOLD/REST + 8 to enter the setting mode. The LOCATION LED 1 will blink yellow.
Press <KYBD or STEP> to select pages 1 or 2. The yellow LOCATION LED shows the current page:
Page 1 allows you to select the tempo input mode, 1 to 3. (Please see Programming Tempo Input Modes, below)
Page 2 allows you to select the assign output mode, 1 to 16. (Please see Assignable Output Mode, below)
Press STEP switches 1 to 8 to select numeric values from 1 to 8. The current value is indicated by a green LOCATION LED.
To access values 9 to 16, press SHIFT + STEP switch 1 to 8. The current value is shown by a red LOCATION LED.
Note: If a setting is on the same LED number as the current page LED, then the LED will flash alternately between the yellow page color and the green or red parameter color.
