Prototracker-modular is a modular synthesizer fork of Prototracker. The idea is that the user can define his/her "sound chip" using basic modules. Each channel has its own "sound chip". Otherwise, the tracker is exactly like any Prototracker fork.

Double click on synth area to add a new module. Left click to connect inputs/outputs (right click cancels). Drag to move modules. See for basic info about modules.


See the releases for binaries.


Simply do make mingw where "mingw" is your platform of choice. Do make to see the supported platforms.

Building for OSX

To install SDL/SDL2 on OSX(using brew), type brew install sdl2 sdl sdl_image sdl_mixer sdl_ttf portmidi. If you are getting the fatal error: 'SDL_image.h' file not found error, type apt-get install libsdl2-image-dev. You should then be able to run make linux.

The binary needs the files in the assets/ directory to work properly.

Using the Xcode project to build on OSX (10.9+)

Recommended to use at least Xcode 6.2 with command line tools installed. Requires SDL2 and SDL2_image framework bundles to be installed in default location (/Library/Frameworks).

You can’t perform that action at this time.
