I cleaned up the patch and made a presentation view for easier interaction and I added three new instruments. The first is a take on FM synthesis and clipping effects that resulted in a harmonized growling sound. For the second instrument, I took the same clipping effect and applied it to a long resonance filter over a click to create a kind of rounded square wave. For the last instrument I took the resonant click and filtered it in a new way to create a sound similar to a church organ.

Here is a sample loop I created using the new instruments and the drums from my old patch.

and here is the code

I separated out the keys into distinct regions and assigned them midi values based on where they were on the keyboard. I then used these note values in different modes to produce different sounds. I also included a boomerang effect that allows the user to record a short piece of audio and then the patch loops it and repeatedly plays it. I created ten drum sound effects by filtering noise in different ways. The main instrument portion is a square wave filtered in a similar way to make the note sound less harsh. The last mode is a saw tooth tremolo that repeated plays the same not so long as it is held. The launch pad is polyphonic and can export the sound in the loop buffer.

The red cubes fluctuate in size with the orchestra, and the green polyhedrons fluctuate with the opera singers.

It will use impulse signals to generate different tones and noises and filter or convolve them to create different effects. I would also include a time-shifting component allowing users to create loops and then play over them as a sort of controlled infinite feedback.  The pad will also have a basic record function so people can export the music they create.

The signal I chose to convolve is a sound clip of me running with a backpack on.

I took my two real world impulse recordings from the entrance to Baker Hall and my classroom in Wean.

I then decided to use a snippet from a song called “Prom Night” by Anamanaguchi for its airy sound to emulate  the sound of running in a dream.

I tried to use the sound of a toilet flush as my last sound to create the sound of running in a cave but it ended up sounding more stuffy than originally planned so I decided to call the last convolution Running in a Nightmare.

For recording, I used the convolution patch we studied in class with an sfrecord~ object to capture the audio.

The first creates negative echoes that trail behind any movement resembling ghosts. The second takes these echoes and rotates them constantly to create a kaleidoscope effect around the center of the video feed. The third filter creates a spiral effect that trails off in to the center of the image. The last filter flips every other frame, resulting in all the positive colored frames and all the negative colored frames aligning. These effects were created by rotating the feedback to varying degrees and subtracting the feedback from the original video feed.

The results of the varying effects.

I started with a close up photo of my friend Miles and I repeatedly put it through the editor.  The photo editor has multiple simplistic sliders such as contrast,shadows, and sharpness. In order to keep each individual jump relatively small, I turned each of these sliders only halfway up. The entire process took 45 iterations to reach the final picture.

The sharpness slider definitely had the most impact on the picture overall as its attempt to remove “blurriness” often resulted in the colors blending later on in the sequence. It is also interesting to see how the sliders changed as the photo changed. Towards the end of the process, the shadow slider which usually makes the darkness in the photo much more prominent, actually enunciated the whites in the photo.
