Aalto vs Bespoke Synth

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.

Bespoke Synth is modular synthesizer software for Linux, macOS, and Windows. Users connect modules in custom layouts to create sounds, with documented tools for sequencing, synthesis, audio effects, sampling, and modulation. The maker describes its DAW-like workflow as focused on jamming and exploration rather than a global timeline. The library provides access to more than 190 modules, and listed capabilities include MIDI controller support, VST plugin hosting, and Python livecoding. Python scripts can control notes and modules; documented integrations include Ableton Link synchronization and OSC message output. Users can import samples, save and load layouts, and write the last 30 minutes of audio to a recordings folder. Bespoke is open source under GPLv3, and all versions are described as identical. A free plan is listed, alongside optional Bespoke Plus at $20 per month and Bespoke Pro at $40 per month. The maker says payments go to the NAACP Legal Defense and Educational Fund. Online documentation and Discord are listed for help and discussion.
