A Guided Tour of the NN-19 > Loading Patches - Pg. 244

Figure 11.11 These waveforms show the same sequence with the Sample Start knob at different positions. SAMPLE START VIA VELOCITY For added effect, the Sample Start feature is linked to the Velocity section of the NN-19 Play parameters. By using the Velocity section to control your Sample Start, it is possible to achieve a wide variation of dynamics with percussive samples. Below the Sample Start knob is the High Quality Interpolation button. This button is used to optimize the sound quality of the loaded samples. This button was discussed in past chapters. To review how it works, see the note in Chapter 7, "Redrum--Close Up," called "Algorithms? Interpolation?" for more information. To the right of the Sample Start knob are the NN-19 pitch controls. These manipulate the pitch of your sample patches using any of the three main parameters: Oct--Shifts the sample pitch by octaves. It has an 8-octave range with a default setting of 4. Semi--Shifts the sample pitch by up to 12 semitones, equaling one octave. Fine--Shifts the sample pitch by 100ths of a semitone and allows for very precise pitch adjustments. This knob has a range of ­50 to 50. Located in the lower-right corner of the main pitch parameters are two additional controls that can be used with them. The KBD.Track button specifies whether the sample patch you have loaded contains variable pitches or a constant pitch. For example, a violin has many pitches, so you would want to make sure that the keyboard tracking button is active. But if you are using a sample that is not pitch specific, such as a snare drum, you can turn this button off, and the pitch of the snare drum will remain constant, no matter what key you play on your keyboard. The Env Amt knob links the pitch of your sample patches to the Filter Envelope, which is discussed later in this chapter. When assigned a positive amount, the pitch of the sample will raise
