Intelligent Key And Scale Finder Plugin

US zplane development releases TONIC 04/11/21

zplane.development has released TONIC by zplane. They describe it as an intelligent key and scale finder plugin that can show key and compatible notes and chords for any audio recording.

Chad Carrier, Product Manager at zplane development, told us, "Many music-makers may have immense talents for creating unique and artistic music, while at the same time also struggle with some fundamental music theory such as determining the key of a piece of music. We created TONIC as a super easy-to-use tool that will help producers, remixers, beatmakers and performers by letting them know the keys for their music and audio, and show them the notes and chords that work within that key."

Here's the details in the company's own words...

TONIC will show users up to three suggested key, with a graph showing the probability level for each suggestion. Using the built-in preview tool, TONIC users can try out notes and chords in the selected key to verify a perfect fit. Knowing the key of a recorded piece of music makes it far easier to develop songs, remixes or beats further, with the recorded audio as a starting point.

TONIC also takes offset in root tuning into account. Recordings of acoustic instruments or made on analog recording equipment may not be perfectly tuned to A=440Hz. TONIC can detect and show the base tuning for the recording, and suggests keys based on that tuning offset.

TONIC by zplane is available as a plugin in VST3, AU and AAX formats. The plug-in also has an offline mode that can quickly analyze audio files before loading them into hardware or software samplers.

Pricing and Availability:
TONIC is available from zplane and from leading online music software retailers for a standard price of €39 (an introduction offer at €29 is in effect until Nov 15th).
