ESSENTIAL PROCEDURES 4. Set the Filter's Velocity Sensitivity & Gain Use Knob 1 to highlight the second function line on the display, then use Knobs 3, 4, and 5 to set the filters velocity-to-cutoff sensitivity, velocity-to-width sensitivity, and gain. Velocity→Cutoff →Q/Width FltrGain With this parameter the filter can set so that its cutoff frequency varies according to keyboard (or other controller) velocity. In other words, the filter cutoff frequency, and therefore the timbre of the sound, will vary according to how hard each note is played. This parameter can be set to both positive and negative values: positive values produce higher cutoff frequencies in response to higher velocity, while negative values produce lower cutoff frequencies in response to higher velocity. Similarly to the "Velocity→Cutoff" parameter above, the "→Q/Width" parameter causes the bandwidth or resonant peak of the filter (depending on the selected filter type) to vary according to keyboard (or other controller) velocity. Although it is on the same function line as the velocity sensitivity parameters, the "FltrGain" parameter simply adjusts the overall gain of the filter - normally to compensate for changes in loudness produced by the filter's response. • In addition to the dynamic filter settings described above, the A5000/A4000 also provides a static filter section which can be set up via the parameters on the lowest function line on the display (EQ). See page 135 for details. • Scroll below the bottom function line for the filter scaling parameters which allow filter response to be varied across the range of the keyboard or other controller. Details on page 135. Step-by-Step EG SETUP The A5000/A4000 actually has three independent envelope generators which control different aspects of the sound: amplitude, filter, and pitch. In this section we'll take a quick look at the basic procedure for setting up an amplitude envelope. Full details on all envelope generators can be found in the section beginning on page 137 of this manual. 1.
