Christopher, Thanks for listening, and I'm glad you enjoyed it!
Once I have cleaned up up a bit of the code to be more stable and presentable, I will gladly share it. I owe a lot to Julius O. Smith in another thread on this list for his advice on using `fi.fb_comb`, and his suggesting that I use that library code definition and extend it to be a higher-order filter (in my case, I went to 2, which was enough). This mitigated some overly bright resonances I was experiencing for all C# notes for whatever reason relating to delay line resonance, I guess. As I go through this Bach project, ongoing tweaks and alterations are likely to continually happen, making the instrument hopefully always evolving and improving. There are many avenues for exploration with this algorithm. Some of them I have explored include things like: using different colored noise for excitation: using a mix of noise and oscillator energy for excitation; sloping parameter relationships across the instrument range to make things like decay realistic (sometimes it's a natural consequence of certain designs, such as when you lowpass filter _inside_ the feedback of the delay), how to best wrap envelopes and global filter envelopes around the core string signal, etc. etc. When I publish the code, I can dig deeper into my process... Thanks again!
