Thanks. Yes, originally I had also wanted it to be continuous. I settled on discrete pitches to make it a little easier to pick up. I will be adding sliders and stuff so you can change the tuning parameters as well as the other other parameters.
Also, there are a lot of features that I will be working on adding. I started this project without much experience in audio programming (I had an idea for something I wanted to make and decided to go for it and I'm learning as I'm going) so until now I have mostly been researching and planning. Development will be picking up now and I will be adding much more control and customization.
