First of all I am not really that far into my physics knowledge (I'm still in high school). I have a projct to design an instrument and explain how is sound produced by my instrument. I was planning to make an electric instrument such as a synthesizer using my computer engineering course knowledge. I just need some help getting started off with this. Can I build a signal generator such that it could be used as an instrument. I wasn't really sure how to start this off. I thought I should search online for a schematic to use.
