Key Features

  • Exposes individual harmonic partials in a dedicated Harmonic Oscillator section for direct additive tone shaping.
  • Uses a harmonic envelope alongside an amp envelope so the spectral balance and loudness contour can move separately.
  • Includes frequency modulation, a filter section, vibrato, and LFO controls for adding motion to otherwise static partial setups.
  • Provides glide, pitch-bend range, and mod-wheel routing for more expressive keyboard performances.
  • Includes an onboard delay for immediate space and repeats while keeping the signal path compact.
  • Supplies 64-bit VST2 and VST3 builds for Windows plus an AU build for macOS hosts.

Description

RE-AXT is Krakli Software's additive virtual instrument for shaping a note from individually controlled harmonics. Its Harmonic Oscillator section places the partials directly in front of you, making it a focused option for producers who want to build bright organ-like colors, bell tones, wiry leads, and changing digital textures by adjusting the harmonic balance rather than choosing a preset oscillator shape.

The interface pairs that partial control with frequency modulation, a filter section, vibrato, LFO, glide, pitch bend, and separate harmonic and amp envelopes. Those controls give a simple additive core enough scope for animated sustains and expressive melodic parts, while the included delay can add space without requiring a separate effect immediately.

RE-AXT is intentionally a compact, old-school-style synth rather than a giant preset workstation. Independent coverage found it easy to tweak and light on CPU, but also noted that the bare sound often benefits from external effects when a more polished or dramatic finish is needed.

Krakli hosts a public RE-AXT product page with a visible DOWNLOAD control and no listed price, trial period, coupon, or expiry language. The official page identifies Krakli as a creator of free VST plugins and lists 64-bit VST2, VST3, and AU builds, so this entry retains the supplied VST-plugin category and uses Krakli's exact product page for the external download flow.

Frequently Asked Questions

What type of synthesizer is RE-AXT?

RE-AXT is an additive synthesizer. Instead of relying on a single fixed oscillator waveform, it lets you set the balance of individual harmonic partials to construct the timbre.

What sounds does RE-AXT suit?

Its direct harmonic controls suit bright organ-like colors, bell-like tones, vintage electronic leads, and changing digital textures. The result depends strongly on the partial balance and envelope settings, so it is best treated as a sound-design instrument rather than a genre-specific preset machine.

Does RE-AXT include modulation and effects?

Yes. The interface includes frequency modulation, filter controls, vibrato, an LFO, harmonic and amp envelopes, and delay. These provide movement and space around the additive oscillator before any external processing is added.

Which plug-in formats does RE-AXT support?

Krakli lists 64-bit VST2 and VST3 for Windows, plus AU for macOS. The official page does not publish more detailed DAW or operating-system requirements, so those are not inferred here.
