Aalto vs Vital

Aalto is a semi-modular software synthesizer by Madrona Labs, built around a patchable interface. Its complex oscillator offers FM, timbre, and waveshape controls, calculating sound dynamically rather than using static wavetables. Every voice has a built-in sequencer with independently controllable, patchable rate and offset. Voice modules include a lowpass gate with vactrol emulation and a patchable waveguide or delay whose feedback loop contains a waveshaper and peaking EQ. A state-variable filter provides simultaneous mixable outputs. Aalto runs on macOS and Windows as a plug-in: Mac provides VST and AU installers, while Windows provides VST. There is no standalone app. A free trial is available, but demo mode plays a reminder sound about every minute and disables patch saving. The listed Aalto license costs $99 as a one-time purchase. It permits installation on any number of computers, though simultaneous use requires one license per computer.

Vital is a spectral warping wavetable synthesizer for Linux, macOS, and Windows. Its oscillators reshape wavetable harmonics through stretching, shifting, smearing, and skewing to create timbres. Users can make wavetables by converting samples with pitch-splice or vocode, editing tables, or generating them from text. Modulation includes drag-and-drop assignment, audio-rate modulation, stereo-splittable and keytracked LFOs, and custom envelope curves. Sound tools include two routable voice filters, eight routable effects, an oscilloscope, and a spectrum viewer. Vital supports MPE and microtonal tuning files, with VST, VST3, AU, and LV2 plugin formats listed. Requirements include 64-bit operation and OpenGL 3 or higher; the listed systems are Windows 10+, macOS 10.15+, and Ubuntu Linux 18.04+. The free Basic plan costs nothing and includes 75 presets, 25 wavetables, and full synth features. Plus costs $25, paid once and includes 250 presets and 70 wavetables. Text-to-wavetable requests are limited to five per day unless a plan unlocks unlimited requests.
