Falcon’s edit section is organized into six sections: Program, Layer, Keygroup, Oscillator, Mapping, and Modulation Editors.


  • Gain, Pan, and Oct/Semi: settings are effective for the entire Program. (But Part volume, pan etc. are defined on the left sidebar.)
  • Streaming: if clicked, samples are read from disk (see [Preferences/Streaming]).
  • Polyphony: max. number of voices for each layer (can be overridden by Layer Polyphony, see below).
    Reducing NoV significantly helps reducing CPU load.
  • Note Polyphony: max. number of simultaneous triggers per note. 0 = unlimited.


  • A Program can have multiple Layers. To select the Layer you want to edit, use Tree or List view.
  • You can select multiple Layers in List view. In this case changes you make will affect all selected Layers.
  • Gain and Pan: Volume and Stereo placement of selected Layer(s).
  • Play Mode: determines how Falcon reacts to new notes when a note is already held.
    Options are: Poly, Poly Portamento, Mono Retrigger, Mono Portamento, Mono Portamento Slide.
  • Portamento Mode: Constant (always the same glide time), or Proportional (the more notes are apart, the longer the glide time).
  • Unison Voices: number of voices triggered per note you’re playing. Range: 1 (default) to 256. Besides higher volume, this has no effects on sound timbre; it can be used quite efficiently when using it as a modulation source, e.g. for pitch modulation (External/Other/Unison or /Unipolar Unison).
  • Custom Poly: Range 0-256; 0 = no specific poly setting for this Layer. Reducing NoV significantly helps reducing CPU load.
  • Vel Curve: right-click and choose between constant Velocity (default 127), or various Velocity curves presets (soft, normal, hard).
    You can also left-click and drag constant values and Velocity curves respectively.
    Rules for entering constant Velocity values: -1.00 to 0: Hard>Normal; 0 to +1.00: Normal>Soft; 2 to 127: constant Velocity.


  • Each Layer can have multiple Keygroups. To select the Keygroup you want to edit, use Tree or List view to select the correct Layer, and then the Keygroup itself.
  • You can select multiple Keygroups in List view. In this case changes will affect all selected Keygroups.
  • Gain and Pan: Volume and Stereo placement of selected Keygroup(s).
  • Trigger Mode: the different Off modes are especially interesting in connection with Sample Oscillators and/or Multi or Step envelopes; Adsr envelopes won’t work. Options are
  • On: default setting
  • Off: Keygroup is triggered when note is released.
  • Off + E: like above but current level of envelope will be used as initial amplitude.
  • Off + V: like Off but note-off velocity will be used as initial amplitude
  • Off + VE: like Off but both note-off velocity and current level of envelope will be used as initial amplitude.
  • Trigger Sync: determines whether a note is played immediately, at the beginning of the next beat, or the next bar. Example of use: triggering loops in a live performance, which should be in sync with the tempo.
  • Exclusive Group: typical example: closed / open HiHats. Value 0 = no Exclusive Group. Maximum Exclusive Groups: 32.
  • Latch: Notes are held. When using Falcon as a Vst, notes are held as long as the DAW is running, or the same note is pressed again.
    After stopping the DAW, currently playing notes are stopped too.


  • Each Keygroup can contain multiple Oscillators. With ‘Edit All Oscillators’ enabled, all Oscs will be edited simultaneously.
    Example: If Osc1 has pitch +8, and Osc2 pitch 0, pitch for both will be +4.
  • Pitch (-48,00 to +48,00; default: 0 cents): use this parameter to modulate pitch. For basic tuning, use…
  • …Coarse Tune (-24 to +24; default 0), and Fine Tune (-100 to +100; default 0). Both parameters cannot be modulated.
  • Gain (-∞ to + 6,00 dB; default: 0dB): Osc output level.
  • Note Tracking (-200% to +200%; default: 100%) determines how incoming Midi note values are transposed.
  • Trigger Mode: you have four options. For our examples we use three Oscillators A, B,C.
  • All (default): OSCs A, B, and C are triggered at the same time.
  • Cycle: Round Robin style - first A, then B, then C, then A…
  • Random Cycle: same as Cycle, but randomized within each cycle. This means no Osc will be triggered twice. Ex: C-A-B, B-C-A, etc.
  • Random: no rules here, everything is randomized. Ex: C-C-B-A-B-B-C-A, etc.


In the Mapping Editor you can define how Keygroups of a specified layer are organized. In the simplest scenario, you have just one Keygroup,
containing one or more Oscillators. In this case you don’t have to worry about Mapping Editor settings. However, you’ll lose a lot of Falcon’s potential.
Let’s recap what you can do with Keygroups:

  • Keygroups can have different Fx (Filters, Distortion, EQs), Pan settings, Trigger Modes (trigger one sample on NoteOn, the other on NoteOff),
    Exclusive Groups, and Modulation sources.
  • you can fade between Keygroups, either by defining different Velocity settings, or different Key Ranges (important for Multi-Samples).
  • you can stack Keygroups on the same note, but with different Oscillators or Samples.

After adding a new Part in the Left Sidebar / Parts view, you’ll get an empty Part without any Program, Layer, Oscillator or Keygroup.
First you have to drag and drop an Oscillator onto the Mapping Editor, then the above mentioned hierarchical structures will automatically be created.
As you drag and drop, you can specify the Keygroup’s key range: lower to the bottom of the Mapping Editor, you’ll get small key ranges, above wider ranges.

  • for exact positioning of the low and high key boundaries, click and drag the respective edge, or enter the notes in the toolbar above the Mapping Editor. You can also zoom in and out, using the little ‘+’ and ‘-’ icons at bottom right of the Mapping Editor.
  • for editing Velocity ranges, drag the Keygroup’s edge up or down, or double-click the values in the toolbar above the Mapping Editor to edit them,.
  • to create key range fades, hold the Command(Mac) or Control(Win) key, and drag the left or right edge of the Keygroup.
  • to create Velocity fades, hold the Command(Mac) or Control(Win) key, and drag the bottom or top edge of the Keygroup.
  • all these settings can also conveniently be edited in the List View.
  • many more options are available when right-clicking in the Mapping Editor, or clicking the little Tool button on top left of the Mapping Editor, e.g.
  • file commands like cut, copy, paste, duplicate, undo, select all
  • move Keygroup to another Layer
  • create Keygroup, optional in a new layer
  • extend, auto-fade Keygroup, etc.

The latter functions are especially important for creating Multi - Sample keygroups.
Talking about Multi - Samples:
You can drag a collection of Wave files from a browser (any browser) to the Map Editor to create Multi-Sample keygroups.

  • Velocity Multi-samples: to get them all placed on the same note, but with different Velocity settings, drag them to the bottom of the Map Editor.
    The Velocity of these samples has to be identified by Falcon, by using numbers for the respective Velocity.
    When using more than 10 sample files, use leading zeros like waveVelo01, waveVelo02, etc., otherwise Falcon thinks that a 'waveVelo10' sample would be ranked after 'waveVelo1', but before 'waveVelo2'.
  • Pitch Multi-samples: to distribute them evenly over the keyboard, drag them to the upper ranges of the Mapping Editor. Then right - click the Mapping Editor and select  'Auto Extend Key Ranges'.
  • You can edit multiple samples at once by selecting them (in Mapping Editor or List view, by using the Ctrl key), and clicking the Batch button:

    After editing, don't forget to save the samples if you want to keep the changes.

Source Editor

The Modulation Source Editor gives you important information about modulation assignments.
It's also the place where you can edit mod sources.

If you click on a parameter knob,

  • the topmost row (1) of the Modulation Editor informs you about the name of the parameter.
  • if it is modulated, the row below (2) shows the modulation source(s).
  • if multiple mod sources are used, click the one you want to see in the bottom part of the Modulation Editor.
  • the Ratio slider defines the modulation amount;
  • lets you invert the mod signal;
  • opens the Modulation Mapper;
  • lets you define a sub-modulation source which defines the intensity of the modulation signal. To add a sub-mod source, right-click and make a choice.
  • in the row underneath (3) you can select the various mod sources, either by using the tool icon, or by just clicking on the relevant mod tab.
    Using the tool icon is the ‘safer’ method, because in case many mod sources are shown in this row, there is a certain risk of deleting a mod source: by accidentally clicking the delete icon.
  • Mod sources are arranged in alphabetical order of their original name, so the Amp. Env comes before an LFO. Renaming mod sources does not change this order.
  • The selected mod source itself will be shown at the bottom of the Modulation Editor.
  • To add a mod source, either use the tool ('Add New...'), or the plus icon.
  • To remove a mod source completely, use the delete icon.
  • To deactivate a mod source, use the disable/enable button.
