XY Screen / XY section

  • The XY pad is a combination of a live, interactive control, and an automated programmable modulation source.
    Use the mouse to control the  6x Free parameters simultaneously, by moving the XY dot around the XY Pad. It is also possible to record these movements as paths and use the XY pad as a programmable two-dimensional LFO.
  • Modulation Destinations
    Inside the XY section are the modulation controls. There are 3 destinations for the X movement and 3 destinations for the Y movement including an amount control.
  • Modes
    The XY pad operates in Free or Mono mode. The Free mode is automatically selected if the Sequencer is active.
  • Loop
    When Loop is On, the XY dot will jump from the end of the path, back to the start of the path, and keep moving. In the < > mode, the XY path loops but travels back and forth along the path. When Loop is Off it travels the XY path one-way only once.
  • Sync To
    By default, when the XY path is replayed, it plays back at the speed with which it was recorded. However, if you want to alter this, the Sync To menu enables you to set the time period the XY path takes to playback. This is set in quarter-beats and is synced to the host's tempo.
  • Points
    Paths are stored as 128 points and the in-between connections. You can change the number of points stored, using the Points menu. The minimum number of points is 2 points, suitable for very straightforward paths. If you return the resolution to 128 points (Off), the original points will be restored.
  • Space Quantize
    Space Quantize restricts the points in the current path to a set of grid lines. The default setting is off, but when you select a grid of 32, 16, 8, or 4 grid lines, Blade-2 will snap all the points to their nearest grid point. The Quantize setting is non-destructive. Disabling Space Quantize will return the points to their original position. 
  • Time Quantize
    Time Quantize sets the update frequency of the XY position. Use this in conjunction with the Sync function to find the optimized balance between update frequency and the number of points in the path. 
  • Play Speed
    The Play Speed control alters the playback speed of the recorded XY Path. It ranges from 1/16 of the set time to 16 times the set time.
  • Smooth
    The smooth control will soften any edges and corners in a path. Use this control if you want to avoid sudden changes (which may sound harsh) in modulation signals. 
  • Speed Control 
    This allows you to set a modulation source (via the menu), and how much this source changes the speed.
  • Edit
    The Edit button located near the XY pad puts the XY path in edit mode. While in edit mode, you can move the path's points around and thus edit the XY Path manually.
  • Commands
    A right-click on the XY display or the command button opens the XY Menu with the following options: Load XY Preset, Save XY Preset.
    The XY commands menu also shows all the previously saved XY Presets. Clicking on one Preset does load it in.

String section edit screen

  • SubBoomBass 2 includes a physical string model to help create string-based sounds, including plucky guitar timbres and metallic hits.
    The model uses a version of the Karplus-Strong model to create sounds. It starts with a short burst of sound, known as the Impulse. The impulse is usually a noise-like component, but SubBoomBass 2 allows you to use other waves too. The impulse is passed through a short delay. The delay is part of a feedback loop. The delay time thus determines the pitch, when the feedback levels are turned up (think of a string resonating). The loop incorporates a low pass filter to simulate the damping of the string.
    Both Oscillators support the string model. Select the Oscillator Model as a String to start the physical model. The main String controls are available in the oscillator screen. The more advanced ones are part of the String screen in the multi-tab screen.
  • The main String Controls are:
    Color, Length, Damp, Wave A/B, Vel>Color, Vel/Key > Length, Vel/Key > Damp, and Vel/Key > Pluck.

    Top - the top MIDI keys sets which sequence is played, MIDI notes 91 selects the Sequence A,  until MIDI note 94 that selects Sequence D.
  • Steps amount 1-16
  • Speed
    The Speed control sets the speed of the Arpeggiator relative to the Host's tempo, for example, 2 x tempo or ¼ x tempo.
  • Sequences A, B, C & D have their own Step & Speed menus, all the other settings are shared settings.
  • Retrigger On/Off
  • Mute / Unmute (per step)
  • Tie (per step)
    Tie links the step to the previous steps and as such extends the note lengths.
  • Slide (per step)
    Slides the pitch from one step to the next. The sliding rate is set by the Slide control.
  • Tune (per step)
    Each step has a range of -3 octaves to +3 octaves in semitones.
  • Vel (per step)
    Vel defines the Velocity value of the step.
  • Oscillator 1 and 2 waveform select per step with the up-down feature, menu features, and pop-up screen as an indication of what waveform/sample is used.
  • Free (per step)
    The Free rows value can be used in the Modulation Matrix as a modulation source. 
  • Ratcheting (per step)
    This allows the step to be ratcheted (i.e. repeated). When it's off the note plays as normal, when set to '2' it's repeated twice, '3' repeated 3 times, and '4' repeated 4 times. When ratcheting occurs depends on the “Ratcheting Menu” / “Vel > Ratcheting” knob (see below). 
  • Tie Mode
    Tied mode lets you select whether tied steps use their own programmed values for Tuning, Velocity, etc, or use the values of the step they are tied to. The following options are:
    Normal - Tied steps do not have an individual slide, tune, velocity, and free settings.
    Special - Tied steps do still have an individual slide, tune, velocity, and free settings.
    Toggle 1 - The Arpeggiator alternates between Special Mode and Normal Mode (Special Mode on the first cycle).
    Toggle 2 - The Arpeggiator alternates between Normal Mode and Special Mode (Normal Mode on the first cycle).
  • Command Menu
    The command menu allows you to Edit, Copy, Paste, Clear, Save, and Load Sequencer settings. A right-click in the Sequencer field or the Command menu button activates this menu. 
  • Step Len
    This controls how long each Arpeggiator note/step is. Note that a 100% setting is needed if you use a tied step!
  • Swing
    Swing is a control that allows you to change the rhythmic feel of the Arpeggiator. It does this by slightly moving every other note relative to a fixed timing grid. Whether it suits your work depends very much on the musical piece you are working on, so we encourage you to experiment with different values here.
  • Slide
    Slide works as an intra-sequence portamento. It sets the time it takes for the pitch to change from the selected step to the next.
  • Vel / Key
    The velocity of the steps in the Arpeggiator sequence can be controlled by their programmed values, by the velocity of the key played that is used to trigger the Arpeggiator or a combination of both. The Vel / Key control sets the balance between these.
  • Ratchet Mode
    Ratchet mode controls how the ratcheting works, the ratcheting can be set to change every time the Arpeggiator cycles (depending on the mode).
    Off -  The ratcheting is always off.
    On - The ratcheting is always on.
    Off / On Cycle -  The ratcheting alternates per cycle, starting with off and then on, and then off, and so on.
    On / Off Cycle -  The ratcheting alternates per cycle, starting with on and then on, and then on, and so on. 
    2 Off / 1 On Cycle -  The ratcheting alternates per cycle, starting with off then off, and then on, and so on.
    3 Off / 1 On Cycle -  The ratcheting alternates per cycle, starting with off then off then off, and then on, and so on.
    1 On / 2 Off Cycle - The ratcheting alternates per cycle, starting with on, then off and then off, and so on.
    1 On / 3 Off Cycle - The ratcheting alternates per cycle, starting with on, then off, then off and then off, and so on.
    Velocity  - the ratcheting is on if the note velocity is below the value set in the Vel > ratcheting knob.
  • Host Sync (Please check back panel for this feature)
    Host Sync synchronizes the Sequencer to the DAW host so that it will start on a quarter-beat. This is enabled by default.
  • Lock Mode
    Lock Mode locks the current Sequence. It keeps it going even when you change Presets. There are 3 modes:
    Off - Lock is turned Off.
    On - Lock is turned On. The Sequence carries over between a change of Presets, but it can’t be modified. It will not change the new Preset.
    Set - The current (locked) Sequence is saved with the new Preset. Locking is turned off in the new Preset.
  • Latch
    Latch frees your hands. When Latch is turned ‘On’ you don’t need to keep holding notes for the Sequencer to continue playing. Tip: you can use a Sustain Pedal to latch and unlatch the Sequencer. Please see the MIDI section on how to set this up.
  • Key Entry
    This switch enables keyboard entry of the notes in the Sequencer. A value of 0 is used as a middle C3.
