Hivetune’s FM software synthesizer Delta6 is being given away for free right now.
In this article we cover the giveaway details and an overview of what Delta6 can do.
1. What Is Hivetune Delta6?
Delta6 is a six-operator FM synthesizer built around a completely open modulation matrix.
Rather than making you choose from a fixed list of algorithms, it lets you route operators into one another freely and see visually how modulation flows through the patch while you shape the sound.
The free version has no feature restrictions and comes with 20 presets. A $4.99 Complete Edition is also available, expanding the factory library to more than 100 presets.
Key Features
- Modulation matrix lets you route the operators freely, so you can build any FM structure and experiment with your own signal paths
- Six FM operators, each with its own tuning, level, waveform and ADSR envelope
- Five operator waveforms – Sine, Triangle, Saw, Square and Noise – for sound design that goes beyond traditional FM
- Feedback control on operator 6
- Drift adds subtle analog-style pitch movement for a warm, organic sound
- Built-in reverb with adjustable reverb size and mix
- Built-in chorus effect inspired by classic hardware chorus circuits
- Velocity sensitivity for a dynamic response that follows your playing
