Since last week, I’ve made a few changes to my project. I added the Max object “sm.ladder~” from the built-in Max package “smFilterPack” (you can find the package manager under File → Show Package Manager). The “sm.ladder~” package acts as a high pass, filtering out high frequencies to change the sound. This in combination with the “lores~” object (which changes the harmonic content) creates a more realistic simulation of a wah-wah guitar effect. I am still using the sewing pedal to control the effect.
I also created a simple visualizer in p5. The text moves up and down based on the volume of my guitar playing. This visualizer would be more useful if it could give information about what effect settings I’m using; for example, if it could display which effects are currently on and which ones are currently off, and the settings I have for each effect. This would create a cool graphic interface that would be easier to read than the Max patch. The image below is a good example of what I’m talking about. Unfortunately, I didn’t get that far, but it’s definitely something I want to explore.
I did a short run through of the “wah-wah” effect and the visualizer in the video below.
