Ardura Actuate (Synthesizer Sampler Granulizer) v1.3.1 VSTi3 CLAP Win Mac Linux [FREE]

Synthesizer, Sampler, Granulizer written in Rust with Nih-Plug and egui
Actuate is a subtractive synthesizer, Additive Synthesizer, sampler, and granulizer made in Rust with Nih-Plug and Egui.
Actuate follows a philosophy of „limited but creative options“ for making sounds.

Features:

Two SVF Filters, a VCF inspired filter, Tilt inspired filters, and two other analog-inspired filters that can be parallel, serial, or bypassed with ADSR Envelopes.
Two pitch modulations with ADSR.
FM Options with an envelope.
12 Oscillator shapes:
The standard: Sine, Triangle, Saw, Ramp, Square, Pulse, Noise.
WSaw – Saw with noise variance to create crispyness.
SSaw – Saw with small variance to create shimmer.
RSaw – Rounded saw wave.
RASaw – Rounded saw wave with random variances.
RSquare – Rounded square wave.
Additive Oscillators with up to 16 harmonics.
FM Supported between Oscillators/samples/granulizer.
3 Different stereo algorithms.
5 Main Filter Algorithms
SVF – 7 Filter resonance approximations for different sweeps in SVF filters
Default – Allegedly the „ideal“ response when tying Q to angular sin response.
Moog – Allegedly a Moog Ladder Q approximation further modified.
TB – Allegedly an approximation of a TB-303 LP further modified.
Arp – Allegedly an approximation of an Arp 2600 further modified.
Res – I made this up – kind of a hyper resonance while still being gentle.
Bump – I made this up – a gentle bump resonance different from the others.
Powf – I made this up – Curves based on Powf math function as it scales.
Tilt Filter.
VCF Filter.
Analog inspired filter idea (Ardura’s V4).
Analog inspired filter idea (Ardura’s A4I).
11 Different FX for post processing.
3 LFO controllers.
2 Pitch Envelopes that can be multilinked to different oscs.
4 Modulators that can be linked to multiple things.
Sampler with pitch shifting or resample stretching.
Sampler supports single cycle waveforms for wavetable-like functions.
Sampler unison and random seek.
Granulizer with ADSR and crossfading between grains.
Any generator can go to any filter.
Samples can be saved into presets.
Stereo width and ultra wide controls.

Hover over any knob (or some labels) for an explanation!

Troubleshooting:

Since Actuate 1.2.8 the new file browser and UI use native text editing. This created some issues in some DAWs outlined here:

FL Studio: No issues!
Ardour: No issues!
Bitwig: When using text input you need to use for space key input
Reaper: VST3 and CLAP text input works if you use „send all keyboard input to plugin“ in the FX menu
Ableton:
Text input works if you add „-_EnsureKeyMessagesForPlugins“ to Options.txt in preferences. See https://forum.ableton.com/viewtopic.php?t=97318
Unfortunately I don’t know where this would be on Linux or Mac so I’m open to help from Ableton users!

Roadmap:

Create an additive module
Create filter release bypass toggle
Find more things to add here
(old items pre 1.3.0)

Create a Preset Browser
Add more reverb styles
Fix some bandpass glitching on certain filter types
Create different stereo spreading algorithms
Make the GUI nicer – see Discussion #26
Look into making the preset loading more reliable
Fix text input not working (right now it’s a OS safe workaround)
Fix file dialog in the process thread (right now it’s a OS safe workaround)

DAWS and compatibility:

Compatible with Windows 10 and up

Compatible with Mac
DAWS
FL Studio tested compatible
Ableton tested compatible
Reaper tested compatible
