Take another look at Volhout's link on the first page—it was implemented in a similar way: https://github.com/keredson/chimes?tab=readme-ov-file ... Frank Hi Frank, I watched the YouTube video (Hark, the herald-angels sing, https://www.cpdl.org/wiki/images/5/54/AMNS_35_Mendelssohn_Harmony.pdf). You're right. The tubes move less than I would expect. That's probably due to the weight of the tubes, as well as the low impact energy. Something you should take into account. The spring tension probably needs to be considered in particular. However, the sound isn't good to me - as a non-musician, a bit off-key, not to say wrong. But that has its charm, too. I should perhaps add that I like "keredson's" (Derek Anderson's) project and respect his work. I downloaded the YouTube video as an MP3 and fed it into Cooledit. It looks like this: I'm curious to see what you find out... I've also ordered two microphones:   Quote   The SPU0414HR5H-SB is a miniature, high-performance, low-power, top-port silicon microphone. Using Knowles’ proven high performance SiSonic™ MEMS technology, the SPU0414HR5H-SB consists of an acoustic sensor, a low-noise input buffer, and an output amplifier. Perhaps the Pico can record and analyze short samples? Kind regards Michael Edited 2025-12-01 19:49 by twofingers
