To Resample the Wave
1. Enter the Sample Manage module
2. Select New.
3. Select resample 16 bit as the source.
4. Turn Off the right side to make this a monaural sample.
5. Press Arm (F5), then play A3 (the 4th A from the bottom of the key-
board). The following screen will appear.
SOUND DESIGNING
6. Set the Automatic Parameters as shown above: Truncate: both,
Normalize: relative, Loop: 1/8.
7. Press Keep (F4), to keep the sample. The E4K will perform automatic
truncation, gain boosting and looping on the sample you just recorded.
The sample will be named, “Wavemake#00”. You now have a single cycle
wave ready to use in building up a preset.
8. Press Sample Manage twice to go out of the module, then back in. Your
new sample will be selected and you can play the keyboard to hear it.
Wave Sequencing
Presets 003~006 also use a layered set of 32 partials, but in this case the
partials are dissonant or the faders have a more complex effect. Experiment
to find the sound that you need, then resample it.
1. Turn the right channel on since these presets are stereo.
2. Set the sample length to 2.4 seconds or longer.
3. Set the automatic loop parameter to: 1/2 + xfd. This should produce an
acceptable loop. (See the E4K operation manual for more information on
the automatic parameters.)
Additive Synthesis
Preset 007 is a special case and here, the 32 harmonics are laid out along the
keyboard white notes, starting with harmonic number one on key A1. Play
the harmonics to get the desired wave timbre before resampling it.
Preset 008 uses a layer of four complex waves to generate new waves for re-
sampling. The faders move the sample loop points around to give different
timbres and fader D adds a chorus effect. Again, when you have the desired
basic sound, use the resampling technique to capture the new wave.
