Three-Body Technology proudly presents Heavier7Strings, a real-time playable sample-based virtual instrument thats brings back Heavy Metal to your productions. Equipped with a complete effect rack and a patterns library, this metal-style guitar library has everything you need!

The love for music, and a desire to create innovative studio technology was the mainspring that made Heavier7Strings possible. With total of 4 years in the making, using only top quality equipment, more than 10.000 samples were painstakingly recorded in 24-bit and 48 kHz. To top it all off Heavier7Strings comes with a self-developed sampler with no compromise on sound quality.

The Effect Rack
What is the first thing to do when one starts a virtual guitar? Usually it is to bypass all built-in effects, as they are mostly too primitive for any serious work. However, the effect rack provided in Heavier7Strings is complete and of production-level quality, not just a toy!

Effects Overview:
  • 19 Heavy Metal Effect Modules: Screamer, EQ12, AMP, Flanger, Pingpong delay, etc.
  • 16 AMPs with styles from heavy metal to clean sound, processing sample rate up to 8X
  • 66 cabinet IRs, four can be mixed simultaneously with different delay, volume and phasing
  • Preset manager allows you to store your own effect presets, along with 200 factory presets

MIDI Patterns Library
Heavier7Strings contains a number of 200 predefined MIDI patterns, together with effect rack configuration. The style of these patterns ranged from metal, rock, pop, clean, and along with non-rhythmic noise and ambient sounds. All these patterns can be dragged into host DAWs, and users can define their own patterns by MIDI clip.

Patterns Overview:

  • 200 factory MIDI patterns together with effect rack presets
  • Various styles: metal, rock, pop, clean, along with non-rhythmic noise and ambient sounds.
  • Draggable into host DAWs
  • Users can define their own patterns by dragging MIDI into
  • Samples and Sampler
  • The sampler used in Heavier7Strings is self-developed, no third-party samplers were used.
  • It has following characteristics:
  • Direct read from disk
  • Shared sample buffer between instances to reduce memory consumption
  • Automatic fade out on disk-read overtime to avoid clicks & pops.

Built-in DSP Engine

  • A built-in DSP engine named THRASH (Tonal/Harmonic Reconstruction and Shaping) is included in Heavier7Strings to provide various tone adjusting functions:
  • +∞RR: in addition to 16x recorded RR at maximum, random timbre and envelope changes are applied on samples to provide more vivid RR playing;
  • True doubling: two guitars playing simultaneously on left and right channel, each has individual random note delay and RR selection.
  • Sample-based LFO: modulate sample pitch with pitch curves extracted from real-world vibrato playing. This technique is adjustable in both degree and frequency, and is more realistic than just modulate the pitch by sine/ triangle wave.
  • Dynamically recoups the formant during pitch-bend.
  • Digitally emulated tone knob and pickup switch;
  • Adjustable tension and resonance.
  • Performance
  • Infinite sustain
  • Hammer-on & pull-off
  • Legato slide in/out
  • Pinch harmonics
  • Tremolo
  • Gliss
  • Palm-mute
  • Picking-noise
  • Polyphonic legato
  • 24 “inspiration keys” to directly trigger specially played sounds/complex performances
  • String and fret board position
  • Up/down picking
  • Strumming: deduce complete chord from part of composing notes
  • Trigger power chords from root note

Heavier7Strings-1.2.1 Changelog
  • Made sounds from AMP and Cabinet modules more similar with those of 1.1.X series.
  • Fixed occasional bad sound in some sound cards.

Heavier7Strings-1.2.0 Changelog
  • Added two new effect modules: HammerMetal and MainTank, which are both distortion modules.
  • Reduced latency of AMP and Cabinets modules.
  • Improved sound quality of AMP and Cabinets by refined resampling algorithm on convolver kernels.
  • Fixed a bug induced in 1.1.5 that different sample rate causes different amount of distortion for AMP module.

1) Install or ReInstall
2) At the first start, specify the path to the library folder, by default in the distribution - Three-Body Tech - Heavier7Strings \ Library \ h7s_samples. When you restart it will not be necessary.

Three-Body Tech wishes you all a Merry Christmas and we do really mean it by giving the present you’ve been waiting for: Ver. 1.5, the major update for H7S!
Besides bug fix, this major update brings you brand new effects and patterns. Please find details below:

Bug fix and improvements:
1. Fixed the bug when you change presets and “You have unsaved preset” dialog shows up. Due to some "multi-thread things", it rarely occurs on some computers and occurs frequently on others, at one time we thought it’s been fixed but recently we got reports and found out it still happens, we feel deeply sorry for the users affected and this time it’s fixed.

2. Improved fret position detection.

3. Lower CPU usage using our updated self-developed sampler.

New features:

New “smooth” parameters have been added to Cabinet, which is rare in most convolution effects. It can flatten comb-like detailed structures in cabinet convolution kernels, and also smooth phase between different frequencies. Adjust this parameter would bring new life to your IR.

Please note there will be some processing time when adjusting “smooth” because it requires quite a lot computation. Please wait a few seconds after adjusting it.

Cabinets also integrated simulation of room reverb. Now you can add some air feeling to your IR.

New effects:

We’ve got tons of emails from users, expressing their love of AMP module of h7s. We won’t stop there. In Ver. 1.5, we provide 4 brand new effects: MetalBall, Perry 65535+, SOLO 1000 and DualRectangle through new techniques of guitar AMP modeling. Perfect match for heavy metal and rock. Combined with two distortion modules added in version 1.2, now you have more options for your tone.

WahX is a brand new wah-effect different from wah-wah. It modeled seven classical wah-wah pedal devices. The pedal can be controlled manually, or by LFO and envelope tracker.

Brand new reverb GoldenPlate. Great for creating a "big and open space" feeling.

New patterns:
We made more than 40 new patterns based on these new effects, hope these patterns will be the inspiration for your new work.

We hope you try it out and let us know any suggestions so we can make them better.

Heavier7Strings-1.5.4 Changelog:

- Fixed the bug that effect rack is not activated before opening UI.

For Update v1.5.4

To enable easy rollback to the previous version,
before starting the installer do
backups of previously installed plugins:

Heavier7Strings (64) .dll
HeavierFX (64) .dll

If you have not previously installed H7S, then at the first start you need to specify a folder with samples.

Added format: VST 32bit
Fixed "A debugger present" error when loading H7S to some hosts.
