Sound Parameter

Blofeld User´s Manual 40

like the modulation wheel or aftertouch can create nice

effects as well.

✻ To create a thick oscillator sound, use a triangular

LFO as PWM Source with full PWM Amount and a

Pulsewidth of around 80. This basic setting is useful

for very big string and lead sounds. When you play

different notes on the keyboard, you might notice

that bass notes sound more detuned than higher

notes. To avoid this behaviour, set Keytrack of the

used LFO to a positive setting between 50% and

100%.

✻ To create a Bass sound, use a decaying Envelope as

PWM Source with negative PWM Amount and a

Pulsewidth of around 80…127. This results in a fat

attack phase, especially when only one oscillator is

used for the Bass.

✻ When you want to create a sound with a wave

sweep, you should set the startpoint roughly

(Pulsewidth) at the desired wave, before you apply

any modulation. This will help you to find the basic

waveform, before the effect of modulations. Note

that you can apply unipolar and bipolar modulation

sources. For example, set Pulsewidth to 64, which

is almost the middle of the wavetable and apply a

slow running LFO to PWM Source to sweep

through the whole wavetable.

PWM Amount -64...+63

PWM stands for pulsewidth modulation. This parameter

determines the amount of modulation that is applied to

the pulsewidth of the oscillator’s square wave. If a

wavetable is selected, PWM Amount determines the

amount of the wavetable modulation. If you select any

waveform other than Pulse or the wavetables, this

parameter does not have any effect. The modulation

source that affects the pulsewidth is selected by the source

parameter described above.

Limit WT on, off

Determines, if the classic wavetables (from Resonant) are

played with or without the additional analog waveforms.

The analog waveforms are a relict from the former PPG

Wave and Microwave synthesizers. If you don´t want to

use these waveforms, use Limit WT to mask it.

• on masks the analog waveforms of a wavetable.

• off plays the analog waveforms of a wavetable.
