When it comes to free autotune VST plugins, Graillon 2 is one of the best. The first thing you’ll notice about the plugin when you open it is its user-friendly layout and industrial-style interface. Due to its GUI design, it’s so easy to navigate. In addition, it has a central waveform display, which shows you the note played and displays the various sound alternatives.
The sounds it produces is impressive and can be inspiring.
When you use Graillon 2’s Correction module, the vocal track starts to snip certain notes. It allows you to control the speed, smooth the note span, edit the range and strengthen the correction. Even though Graillon 2 sounds good without all the controls, you are given even more creative freedom with them.
With the correction amount and smooth knob feature, you can produce an array of vocal pitch correction effects that will work for your music. Beyond this feature, the program has many other vocal processing effects such as pitch shifting, bitcrusher, etc.
When it comes to autotune VST plugins that you can get for free, Graillon may be the best available.
GSnap was the first free autotune VST plugin available and still is regarded as one of the best pitch correction plugins. GSnap offers many of the same features as MAutoPitch and Graillon 2 have to offer, but it has one distinctive feature that the other two do not have. It allows you to adjust notes based on the MIDI signal.
For instance, using other autotune plugins means you need to rely on the plugin’s programming to determine the vocal melody and make adjustments to the pitch. On the other hand, if you’re using GSnap, you input the MIDI notes into the plugin, and it’ll tune the sound using those sequences.
With this method, the plugin gets clear instructions on how the sounds should be tuned, reducing the possibility of mistakes. GSnap automatic pitching functionality ensures fantastic results.
There are two drawbacks to this plugin:
This autotune plugin was developed by the Japanese in 2010 and is helpful in fine-tuning your vocal’s pitch. Being an older autotune VST plugin, it doesn’t look the best. However, it does offer outstanding autotune functionality. KeroVee will let you choose the notes to correct, and you can input the MIDI notes in real-time.
KeroVee offers the Nuance parameter feature so that you can keep the subtle pitch changes, ensuing the autotune is hidden.
Two negative aspects to KeroVee:
MeldaProduction created its MAutoPitch plugin that can be downloaded for free. Its main pitch correction module provides you options for base, depth, detune and speed. Its speed knob can control how quickly the plugin responds to the input signals’ pitch changes. If you use a low setting, it produces a subtle autotune effect.
MAutoPitch comes with an effects module with options for formanting, width and dry/wet. Fomanting works by lowering a sound’s perceived pitch while keeping its true pitch. For instance, a vocal recording can become more masculine without affecting the melody’s integral pitch.
This is a feature that Graillon 2 also provides with its user-friendly design, but it’s MAutoPitch that goes beyond with its limiter and stereo adjustment.
This free plugin was created to help with minimal pitch correction on vocal recordings and samples. X42 Auto-Tune will resample a signal and loop it, designed to correct minor errors. It’s not for producing heavier robotic effects.
Similar to GSnap, it can input signals using certain MIDI notes or where you can specify a set of fixed notes for it to use.
It’s not entirely user-friendly but has features that make it worthwhile compared to other autotune VST plugin programs.
