open-nsynth-super | Open NSynth Super is an experimental physical interface for the NSynth algorithm

open-nsynth-super is a C++ library typically used in Internet of Things (IoT), Arduino applications. open-nsynth-super has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

There are several distinct components to each Open NSynth Super unit: a custom PCB with a dedicated microcontroller and firmware for handling user inputs; a Raspberry Pi 3 computer running Raspbian Linux and an openFrameworks-based audio synthesiser application; and a series of scripts for preparing audio on a GPU-equipped Linux server using the NSynth algorithm. In addition to the software, firmware, and hardware, there are files for creating a casing and dials for the unit. The electronics are built around a Raspberry Pi 3 running Raspbian Linux, and a custom PCB used to read the inputs and control the outputs. A microcontroller on the PCB manages the physical inputs: there are four rotary encoders on the four corners for instrument selection; six potentiometers below the interface to control the position, envelope, and volume settings; and a capacitive grid on the surface of the PCB (exposed through the top layer of the case) used to select the mixing point of the four instruments. More information on the electronics, hardware, and firmware can be found here, and here. A complete bill of materials for the case and electronics is available in this Excel spreadsheet. Open NSynth Super runs a multisampler audio application built on openFrameworks to process incoming MIDI note data and generate sound output. More information about this application can be found in the software readme file. We designed a case for the electronics that can be easily manufactured with a laser cutter, and held together with standard screws and fittings. This design is easily customisable using different materials, colors, dials, and shapes. Read more about this in the case readme file. Audio for the Open NSynth Super instrument is produced by the NSynth algorithm. Because generating audio requires a great deal of processing power, this repository includes a set of scripts that you can run on a server which will take any audio recordings of your choice and convert them into a format compatible with the instrument. For more information, see the audio readme file or the audio creation overview in this document.
