Thank you Peter. I started to modify the original using the IC you provided. I didn't start from a blank breadboard, I copy and pasted the schematic so as to preserve the design. I deleted the breadboard so I can see the rats nest cables unhindered.
After having done this I still see a huge number of rats nest lines. Is this the bug you mentioned?
How did you create this file you uploaded? Did you use the existing components or did you have to recreate the schematic from a blank project in order for the file not to be corrupted?
Thank you for all your help, I hope to soon have a booming Bass Kick and that this will help others trying to learn percussion synthesis.
