[. . . ] Following along the Morph axis you can see that the filter response smoothly interpolates between the two filters. Morph B Filter Amplitude A Filter Morph Frequency The Z-plane filter has the unique ability to change its function over time. 46 Orbit V2 Operation Manual PROGRAMMING BASICS This is the essence of the Z-plane filter. Through the use of interpolation, many complex parameters are condensed down into one manageable entity. Consider, as an example, the human vocal tract, which is a type of complex filter or resonator. There are dozens of different muscles controlling the shape of the vocal tract. When speaking, however, we don't think of the muscles, we just remember how it feels to form the vowels. A vowel is really a configuration of many muscles, but we consider it a single object. In changing from one vowel to another, we don't need to consider the frequencies of the resonant peaks!You remember the shape of your mouth for each sound and interpolate between them. Filter morphing can be controlled by an envelope generator, an LFO, modulation wheels or pedals, keyboard velocity, key pressure, etc. The Q parameter on the Orbit filters can only be changed at note-on time but can control various parameters such as boost/cut and mouth cavity size and of course, resonance or Q. Chapter 4: Programming Basics 47 PROGRAMMING BASICS ORBIT SIGNAL FLOW Going back to the block diagram for a single channel we can re-examine the complete signal path. Z-Plane Filter Morph Q Volume Instrument Pitch Sample Start R DCA Pan Tone L Aux. DAHDSR Velocity Volume AHDSR Instrument This is the sampled sound wave. The pitch of the instrument can be modulated by any modulation source. The sample start point can only be modulated by a velocity or key source (see the next page). Tone Tone is a simple tone control which can be used to brighten or mute the sound. Tone can only be modulated by a velocity or key source (see the next page). Key velocity is commonly used to modulate the tone so that the harder you play, the brighter the sound becomes. Morphing Filter The Morphing Filter is used to shape the harmonic content of an instrument. The auxiliary envelope is commonly used to dynamically shape the harmonic content over time. See page 61 for complete descriptions of each filter type. DCA Digitally Controlled Amplifier. Together with the Volume AHDSR, the DCA is used to shape the volume contour of a sound. Key Velocity is often used as a modulation source for the DCA so that the harder you play, the louder the sound becomes. Pan Adjusts the balance of sound to the left and right channels. Pan can be modulated by any realtime or note-on modulation source. 48 Orbit V2 Operation Manual PROGRAMMING BASICS LFO 1 Amount Rate Primary Instrument Pitch Sample Start Tone Z-Plane Filter Fc Q R DCA Pan Keyboard Modulation Sources Key Number, Key Velocity Destinations Off, Pitch, Primary Pitch, Secondary Pitch, Volume, Primary Volume, Secondary Volume, Attack, Primary Attack, Secondary Attack, Decay, Primary Decay, Secondary Decay, Release, Primary Release, Secondary Release, Crossfade, LFO 1 Amount, LFO 1 Rate, LFO 2 Amount, LFO 2 Rate, Auxiliary Envelope Amount, Auxiliary Envelope Attack, Auxiliary Envelope Decay, Auxiliary Envelope Release, Portamento Rate, Primary Portamento Rate, Secondary Portamento Rate, Filter Fc, Primary Filter Fc, Secondary Filter Fc, Filter Q, Primary Filter Q, Secondary Filter Q, Sample Start, Primary Sample Start, Secondary Sample Start, Pan, Primary Pan, Secondary Pan, Tone, Primary Tone, Secondary Tone L Volume LFO 2 Amount Rate Portamento Rate Volume AHDSR Atk Dec Rel X-Fade Auxiliary DAHDSR Atk Dec Rel Amt Secondary Instrument Pitch Sample Start Tone Z-Plane Filter Fc Q R DCA Volume Pan L Volume AHDSR Atk Dec Rel KEYBOARD CENTER VELOCITY CURVE KEY NUMBER VELOCITY Keyboard and Velocity Modulation Sources KEYBOARD AND VELOCITY MODULATION The Keyboard and Velocity Modulation diagram shows the possible routing of Key Number (which key is pressed), and Velocity (how hard the key is pressed).
