Hi Faustian-folk, I wish to announce the latest video in my series showcasing the fruit of our wonderful DSP software:
Bach, WTC Bk II, #3 in C-sharp major, BWV 872. Super-sunny and joyous/optimistic piece, a standout for me in the collection. The prelude has a joyous serenity followed by a burst of energy in a new tempo near the end, and the fugue is a combination of humor and nobility simultaneously as only Bach can do. https://youtu.be/KyiaagcLhZg?si=k_-UOwX0N8mk-Dg- You can peruse the superclav faust code here, if interested: https://github.com/akjmicro/superclav_code/ I've made some changes since the last iteration: * removed any oscillator (saw) driving signal * implemented a simple lowpass in the feedback chain, and removed the "outer" filter/env. The result has a better naturalistic decay, I think * pink noise is the raw excitation * vastly reduced the number of controls and hard-coded values I found to be nice..."set and forget" * corrected the temperament data values to be the actual ones I wanted/thought they were all along. I hadn't realized I had old values for Niedhardt III temperament in there, and the comment implied it was my own (and the late Geoarge Secor's) temperament. Now, it is that temperment, which takes advantage of the nice rational but wide (noo too wide, but wide enough to be within the authentic 18th century bounds) 24/19 interval. (A pure JI major third being 5/4). In the process I learned the real reason for a subtraction of N samples delay inside the delay-line expression, and its effect on tuning. This gave me knowledge and confidence on how to fix tuning issues in any string-model-based-on-delay in any code anywhere. A nice lesson. Thanks again to the wonderful devs for bringing Faust DSP our way! If anyone has any questions at all about this project, including the DSP code, the music, the tuning, let me know, I'd love to discuss and answer them. Comments also welcome.
