Swivel Audio Knocktonal

Note-based resonant drum tuning

Overview

Knocktonal is a note-based resonance enhancer, allowing users to boost (or cut) resonances as well as their corresponding overtones. Simply put, Knocktonal allows you to tune your drums without the need for destructive re-pitching.

Resonance EQ

The resonance EQ section is where the power of Knocktonal really shines. This is the primary place where usage will occur. The resonance EQ is designed to push a root note, and all accompanying harmonic overtones, both even and odd.

Subtractive EQ

The subtractive EQ section of Knoctonal is designed to remove any unwanted resonating frequencies that preexist in the audio you’re working with. This is useful in order to achieve a “blank slate”, before enhancing any new resonances.

More Control

• MIDI In: MIDI Channel 1 controls the frequency of the resonance EQ, and MIDI Channel 2 controls the frequency of the subtractive EQ.
• 2 MODES: Knocktonal allows you to work in overtones mode, or octaves mode. Overtones mode enhances both the even and odd harmonics of your root note, and gives you control over which of these overtones are more present. In Octaves mode, Knocktonal will push all octaves of your root note, ignoring the overtones.
• Built-in Limiter: When turned on, this will limit the volume of the signal to prevent unwanted distortion caused by larger resonance boosts of the signal.

Features

• Resonance EQ – Push or cut a root note along with its harmonic overtones, allowing precise tonal tuning without destructive pitch-shifting.
• Subtractive EQ – Remove unwanted resonances from your audio to create a clean foundation before enhancing new tonal content.
• MIDI In – Control the Resonance EQ and Subtractive EQ frequencies in real time using MIDI Channels 1 and 2.
• Built-in Limiter – Prevent distortion from extreme boosts with an integrated limiter that keeps your signal clean and controlled.
• Overtones Mode – Emphasize both even and odd harmonics of your root note, with control over which harmonics are most present.
• Octaves Mode – Focus exclusively on octave multiples of your root note for a more tonal, less harmonic-rich enhancement.
