Analog Box

Analog Box is a free software synthesizer developed by Andyware. Available format(s): for Windows.

Analog Box is a low level, circuit based, modular software synthesizer. You put sound objects on the screen, connect them together, listen and adjust. When you find something you like, you can record it to a wav file, or just save the circuit and play it again later.

ABox is somewhat like the vintage synth’s of the ’70’s in that there are separate modules with lots of patch cords, knobs, buttons and displays. But you also get the computational ability offered by modern CPU’s. Features like FFTs, Differentials and Digital Control open up realms of sound design never dreamt of before. With the advanced capabilities offered by VSTi, USB/HID, MIDI and DirectShow you could conceivably play your favorite video soundtrack through a plugin adjusted by a glove controller.

With ABox2, editing virtual circuitry has never been easier. Get objects from the palette, put them where you want, connect them however you like. Adjust parameters using one click popup panels then move on. No questions asked. Make a mistake ? Hit Undo, all fixed. Like that section of circuitry ? Clone it, now you have another one. Really like that section of circuitry ? Group it together, create a new object. Now you can paste it anywhere.
