Heavier7Strings is a seven-stringed metal-style virtual guitar instrument with effect rack and MIDI pattern library.

Key Features:

  • Self-made sampler to perform direct disk read and fade-out on read timeout.
  • Infinite sustain.
  • Built-in DSP to provide tone adjustment functions, such as:
    • random timbre and envelope change atop of recorded RR;
    • timbre change on pitch bend, pitch shift and vibrato;
    • digitally emulated string tension, resonance, tone knob and pickup switch.
  • Vibrato by sample-based LFO that are adjustable on both frequency and depth.
  • Automatic determination on string/fret board position and up/down picking.
  • Trigger complete strumming by part of composing notes.
  • Trigger power chord from root note.
  • "True doubling": two guitar playing with individual RR state and randomly disturbed note playing time.

The Heavier7Strings includes a production-level effect rack that has following features:

  • Commonly used modules: AMP, Cabinet, Overdrive, Screamer, Flanger, Ping-Pong Delay, etc.
  • Modules can be freely-assembled.
  • AMP works in 2-8x super sampling to avoid high frequency aliasing.
  • 16 AMP styles from heavy metal to clean sound.
  • 66 Cabinet factory IRs (impulse response) including various speakers and mics.
  • User customizable cabinet IRs via WAV files.
  • At most four IRS can be mixed with different delay, volume and phasing.

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 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.

At first you have to know I'm not guitar player and well I'm not even a musician. I can't and I will not compare it with real guitar but I will rather treat it as virtual instrument since well - it is a virtual instrument.

Sound is very important but UI, workflow, performance and stability is important too. I do enjoy sound design but from sampler I mostly expect usable sound without spending too much time to tweak the instrument. With H7S you can have that but of course you can tweak it to your liking. Versatile and very usable not just for heavy riffs but also for clean sound. Fast loading and better performance compared for example to some similar guitar libraries in kontakt and very stable (for me FLStudio 12.5 64-bit no single issue during testing). Clean and resizable UI that is easy to navigate. Awesome sound and many usable features.

My first e guitar was Shreddage 2 SRP which is nice but it was more suited for heavy stuff so I have added and Evolution Dracus to my arsenal for more clean sound. Both libraries are good and usable but ... Now I have also added H7S to my instruments pool and it will become my main tool for electric guitar sound. It may be more expensive but better sounding, more versatile and it come it very good effect rack that can be used separately. So at the end it is cheaper.

During my first test with H7S I made short and simple track using 3 slightly modified factory presets - instances. One instance for clean, one for rhythm and one for lead/solo accompanied with strings, brass section and some orchestral drums ensemble in middle for some hybrid music experience. It is not best showcase but it was made right after my first use of this instrument. That's really show how easy is to use this beast.

Peacefull Destroyer

I tend to disagree a little bit. When rating an instrument I think all things in the instrument should be considdered. HS is pretty good when playing the keyboard, especially for things like heavy (hence the name) and metal. However there are a lot of guitar instruments that are in that respect. When it comes to other features IMHO others excell. HS presets ranges from very quite to EXTREEMELY LOUD. Annoying. The enclosed presets are not to my liking and the "grooves" or "solos" are mostly unusable in a song (but can serve as an inspiration). If you are after a guitar software that you want to play the whole thing on your keyboard it is worth looking into, but the guitars from Ample Sound, Music Lab (Real Strat/LesPaul/8), Impact Soundworks (Shreddage) etc should also be considdered, especially when combined with a good amp/FX simulator (like S-Gear or similar). If you are looking for a software that kind of helps you as a non guitar player and not so skilled at the keyboard, the other three mentioned are better choices.

I have been using virtual electric guitars for years to reinforce my productions, I like to work with them at an extreme level of realism. Unfortunately no current library is perfect.

Ample Sound and MusicLab has a great range but still sounds a bit "artificial" and lack of sampling, Prominy V-Metal has various chord captures but not enough layers and round robins, plus an GUI from the old last century...

Of all these the best are Shreddage Guitars (especially Jupiter and Hydra) give you endless options to control the sound, they have resonance control, release and pick attack samples (very important)... if there is something bad I would have to point out, it is the handling of the articulations that it's a bit uncomfortable with TACT, as well as some samples that sound very freaky in some frets.. yes, it's a guitar that requires a lot of programming to achieve a good result.

For its part, HEAVIER7STRINGS brings together several of the best features of all the others, the pick attack (although it is not completely controllable) gives great realism both in the leads and in the rhythmic parts. In general, its sound is the roundest and most complete. However, it is not perfect either, it lacks multilayers for the samples, especially the palm mute. You can't manually control which string you want to use either... The interface looks good, but I would improve the visibility a bit and change the font. It lacks a viewer that shows which joint is being used at that moment (super important) as well as better handling of hammer ons and slides... However, as I said, I consider it to be a very complete product... .

Unfortunately, it has fallen into oblivion, either due to lack of marketing or the company's inability to carry out such a complex project. Gone is the promise of a Heavier9Strings that never arrived and a community that long ago stopped seeing updates that could easily solve all the deficiencies of this magnificent software.

If I were the developers, I wouldn't invest time in the riffs or effects section (at least not as a priority)... In the end, 99% of the users will use their dedicated virtual amps and the riffs, more than a demonstrative resource, won't interest them. Focus on sample content, round robins, layers, slide transitions and controls, more FX's samples, pick attack, symphatetic resonance and other little nuances that are needed for create a realistic sound...

Hopefully one day, not too far away, good news will arrive in this regard.

PLEASE TBT!!! Here me!!.
