OSU Online CS capstone project. The goal of our project was to build a digital synthesizer application, with a visually stimulating display and user interface. After a full term of work, our team is ready to present: The Rorschach Synth. Built primarily with the JUCE C++ framework, the application can run on Windows 10 and Mac OS X 10.11+. A user can craft sounds by mixing three oscillator waveforms, adjusting envelope and filter parameters, and applying a variety of effects. The randomly generated, ever-changing display is based on the Rorschach inkblot test and provides some creative inspiration to the player. Notes can be played via the on-screen keyboard, computer keys, or external MIDI device.
Located in this repository are two files, rorscharch_synth.pkg and rssetup.exe. rorscharch_synth.pkg is an installer for MacOSX 10.11+, and rssetup.exe is for Windows 10. Follow prompts to install application.
Alternatively, you can download the app from our landing page: https://sjudkis.github.io/rorschach/
JUCE must be used to create the necessary environment files.
The synth has been tested and runs on Windows 10 and mac OSX 10.11+.
Installation on both Windows/MacOS is basically the same.
- Clone this repository.
- With juce installed, open
rorschach_synth/rorschach_synth.jucer. - Choose the correct platform, and click VS2019/Xcode icon to create platform-specific code.
- Build project in your IDE, and the synth should open.
Press info key at the top left of the synth to see labels of buttons and sliders in the blot region.
This section gives a brief, high level description of each effect.
When clicked, spawns a slider and a button that control the tempo and note pattern of the arpeggiator. Hold down multiple notes and the synth will cycle through them. The cycle can be from low to high, or randomly selected.
Adds a delay that successively plays note at lower and lower volume. The greater the slider has traveled, the longer the delay. It is a combination of a ping-pong and tap delay.
Modulates attack, decay, sustain, and release of the sound. Controlled by the A/D/S/R rotary dials, and the modulation is represented in the graph below.
Sets the overall output level of the synth.
Adds a TV-static-like effect to the sound.
The high pass filter allows only frequencies above the chosen threshold to be heard. Low pass allows only frequencies below the threshold.
The Low Frequency Oscillator slider controls the frequency that a parameter changes and has two modes:
Frequency Modulator (FM) - This manipulates the frequency of the Oscillator waveforms. Amplitude Modulator (AM) - This manipulates the gain applied to the waveform.
The synth contains three oscillators to generate the sound: sine wave, square wave, and saw wave. Each oscillator volume can be adjusted independently to create unique waveforms.
Adds a reverb effect that simulates the sound echoing off the walls of a room. The dial controls how much of the effect is applied.
