Outsim SynthMaker v1.1.7

SynthMaker is an audio programming tool that allows anyone to create their own sounds, virtual instruments and effects without having to write any code. These instruments and effects can then be used for playing live via MIDI or as VST plugins for use in making music using any of the popular recording software. Program without writing code, see the results in an instant

Program without writing code, see the results in an instant

SynthMaker allows you to program without writing a single line of code. This is achieved by linking together components.
Components are simply building blocks that perform some action. All changes take effect instantly with no build time.

A level for everyone

SynthMaker's components allow you to go to the lowest possible level. This gives you ultimate control over behaviour.
Of course you don't need to make use of this ability all the time, quite often mid-level and high-level modules will do the job nicely.
