Aalto vs SynthMaster 3

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.

SynthMaster 3 is a modular software synthesizer available as a standalone app and plug-in for macOS and Windows. It offers VAnalog, additive, vector, wavetable, granular, phase modulation, phase distortion, frequency modulation, pulse width modulation, ring modulation, physical modeling, and SFZ sample playback. Each instance can contain up to 16 layers, with each layer holding up to 16 modules and 32 modulation sources. The software includes waveform, wavetable, and multi-sample editors; multi-samples can be imported from WAV or AIFF files and exported in SFZ format. Each layer has a MIDI output channel for routing arpeggiator or sequencer output to different DAW tracks. Plug-in formats are VST2, VST3, AudioUnits, and AAX. The product includes 3150 factory presets. SynthMaster 3 costs $99, paid once and includes 6 free expansions. A free player and demo are also available. The demo stops after 30 minutes, adds noise every minute, and disables WAV wavetable and SFZ multi-sample export.
