Leapwing Audio RootOne
Multiband Subharmonics Plugin
A Unique Multi-Band Subharmonics Generator and Shaper that Gives Punch to Your Low-End!
RootOne lets you add and shape 3 bands of subharmonic content for the perfect tonal balance. Whether you need to make one part of your mix meet the others, or if you need more low-end overall, you can take the second-guessing out of your workflow when bass matters most. This unique plugin completes your low-end with clean, phase-aligned subharmonics, and you’ll never have to worry about frequency interference or detachment.
The analysis-synthesis algorithm is effective across a far wider range of sources than traditional solutions, which means more applications, more trust, and more bass. The perfect kick, bass guitar, or bass synth pluck are only a few clicks away.
Unique Clean Algorithm
Add artifact-free, phase-aligned bass subharmonics thanks to intelligent analysis.
Full Harmonics Shaping
Add tape-like and tube-like harmonic saturation with low-pass control.
Multi-band Sub Generation
Trust the unique clean algorithm to give you full control of the low-end.
Beautiful Design with Optimal Workflow
Beautiful Retina design with all controls on one screen. Clear metering lets you see the changes as you hear them.
Unique Analysis-Synthesis Subharmonics Algorithm
Phase-Aligned Subharmonics Generator
Relying on pitch-detection rather than pitch-shifting means our plugin has wider applications, a better sound, and can be trusted over traditional solutions.
The analysis-synthesis algorithm generates clean, phase-aligned subharmonics for a subtle and musical addition to your bass that fits your original sound.
Full Control Over Your Tone
Each subharmonic band offers control over dynamics, release, and drive.
Add lower midrange harmonics for the control you need and get the perfect fit for your new bass frequencies.
Overall, this means you’ll never have to worry about the character or fit of your additional subharmonics.
Quick and Intuitive Interface
It looks good and it sounds good, because we were thinking of you when we designed it.
Our algorithm makes it easy to get a good sound and the simple interface lets you visualize the adjustments you make as you hear them.
