JBT Tones
From an empty project to a finished vocal stack.
Four tools for songs in rock, metal, punk and post-hardcore: a vocal plugin, a plugin for tight vocal stacks, a rhythm guitar generator and a launcher that turns a song into a Logic project.
The four tools
The tools
JBT VoxVocal plugin for rock, metal and punk: tuning, harmonies, doubles, scream engine, delay and reverb in one window, with 34 presets.
JBT VoxLockARA 2 plugin that automatically aligns doubles, backings and gang vocals to a guide track. No capture, no transfer.
JBT Riff BuilderWrites complete rhythm guitars as MIDI for 21 genres, with real chord shapes, palm mutes and double-tracked takes.
JBT Logic LauncherDetects a song's tempo, tempo changes, key and tuning and turns it into a ready-made Logic Pro project.How the tools fit together
Each tool takes over one step that otherwise eats up time in production. Together they cover the path from a reference song to mixed vocals.
