Modulation mappers in Falcon let you modify the response of a given modulator. A mapper can be used for numerous purposes, here are a few examples:
Creating exponential modulation curves, or curves which only start at e.g. 50% of the modulator range.
- right clicking on the mapper will open the mapper library which also contains a variety of exponential curves (positive and negative) with different slopes.
- you can also draw your mapper curve free hand with the mouse.
Scaled modulation responses
- E.g. the modulation wheel is assigned to oscillator pitch with a total range of 1 octave, the mapper is set to a size of 3 steps with a total range of 12 semitones, interpolation deactivated, “Integer Output” engaged, step 1 at zero, step 2 at +7 semitones, step 3 at +12 semitones. Moving the wheel will then only create a perfect fifth at middle position and an octave when fully engaged.
- Harmonic scales can also be created, e.g. a bipolar pentatonic scale with a 2 octave range, set total range to -12/+12, size to 10 steps, then edit the steps/pitches to -12/-10/-8/-5/-3/0/+2/+4/+7/+9/+12 – this mapper can now be used to scale a modulator like a tempo-synced random LFO which will generate random pentatonic melodies synced to host tempo.
- Chromatic scales which can then be applied to e.g. a step modulator. As the step modulator in Falcon is not scalable and only works by entering percentage values (not pitches), this is a very helpful feature when creating re-triggering pitch sequences on keygroup level.
- Note that when assigning a modulator to oscillator pitch, the modulation range slider needs to be set to 1 semitone (the smallest possible step size), the non-interpolated mapper will then take care of the rest.
- To edit the mapper scales, double click on each step and enter the value numerically with your keyboard, dragging the values with your mouse will not get you very far.
