Actuate

Actuate is a subtractive 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, and Tilt 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.
• 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.
• 10 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.
• 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.
