No Filters!? Bolt Harmonics Synthesizer from Nektar Tutorial ① Basics & OSC Section

About Bolt’s Oscillators (OSC)

This plugin has a main OSC and a second OSC, allowing for sound changes made with OSC2.
Harmonics are added to edit the sound, and the filter section included in most synthesizers is not built in.

There’s a variety of preset waveforms as well.
You can select a preset waveform and use the OSC parameters to edit the sound.

Edit the following parameters to make changes:

• HARMONICS: Adds harmonics to add characteristics to the sound
• ROLLOFF: Enhances high harmonics and raises high frequencies
• NOISE: Adds noise to the sound; useful for sound effects

The harmonic types can be changed from the top of the OSC section.
These work similar to a synthesizer’s filter section.

• ODD: Removes even harmonics and creates a Pulse/Square type sound
• INV: Inverts the waveform; used for FM and OSC mixing sounds
• DEEP: Lowers high harmonics, and increases the low end sounds. Has a low-pass filter like effect.

This section is used to control the OSC pitch functions.

• SHIFT: Edits the OSC in half-step (semitone) increments
• DETUNE: Adjusts the OSC pitch in Cents
• SUB-OSC: Adds in a -1 octave sound and thickens the sound

Volume/Pan Control

Each OSC’s volume/pan can be adjusted individually, allowing for nuanced sounds.

The red fader next to the volume fader controls the [Drive], allowing you to add a saturation like effect to the sound.
This works great for fattening the sound and blending it into the mix.

The [MAIN VOLUME] allows you to control the overall volume.
Keep the balance between OSCs while adjusting the master volume.

Using FM to modulate

An [FM] is included in Bolt modulate sound.

Turn on the [FM] button, and turn the knob below to adjust the amount.
By changing the [SHIFT] of each OSC, you can modulate using your OSCs.

In addition, by using the [XM] button, you can cross modulate OSC1 using OSC2.
When doing this, the OSC2 volume can be set to 0.
