PART 3: EFFICIENTLY COMBINING SAMPLES INTO PRESETS
Part of creating a good Preset is to get into a “rhythm” where you’re punching up
parameters as if the whole process was second nature. The following example shows
the flow of a typical sampling session from start to finish.
I. The Situation
You have a portable, toy synthesizer that has about seven really great patches and no
keyboard dynamics. You’d like to take it on the road, but it’s real fragile; so, you decide
to sample the seven patches into the Emulator II, and add keyboard dynamics while
you’re at it. We’ll suppose that these neat sounds are called “Electric Piano”, “Trumpet”,
“Gong”, “Noise”, and “Synth 1 - 3”.
II. Getting ready
First, let’s do a little bit of planning. We’re trying to fit a fair amount of sounds into
memory, so we’ll minimize the number of Voices per sound. Here are some suggested
ways to divide up the keyboard for different numbers of Voices:
3 Voices
Low Orig Hi
C1 C2 A2 Lower Voice (Voice 1)
Bb2 F#3 D4 Middle Voice (Voice 2)
D#4 C5 C6 Higher Voice (Voice 3)
Because transposing changes the timbre of the sound, sometimes three Voices will not
realistically cover the keyboard. Often you can stretch the lowest Voice to cover two
octaves, and use three Voices for the upper three octaves.
4 Voices
Low Orig Hi
C1 C2 Bb2 Voice 1
B2 F#3 B3 Voice 2
C4 F#4 B4 Voice 3
C5 F#5 C6 Voice 4
For greater bass range fidelity, use octave by octave sampling.
5 Voices
Low Orig Hi
C1 F#1 B1 Voice 1
C2 F#2 B2 Voice 2
C3 F#3 B3 Voice 3
C4 F#4 B4 Voice 4
C5 F#5 C6 Voice 5
