All our violin frequencies have changed - in particular ETMX has moved up quite a bit (see alog 43331). The lowest frequency is 501.553HZ, and the highest frequency is 516.778Hz. So our frequency spread is about 3 times bigger than before. I designed new violin stop filters for DARM (DARM2 FM6,FM7,FM8):
- The fundamental is now 6th order (was 4th). This gives similar phase at lower frequencies.
- The 2f and 3f harmonic are wide enough to catch both actual violin modes and mathematical up-conversions (from possible DCPD saturations).
- For the 4f and 5f I only cover the actual violin modes - they get too wide otherwise. The 6f again catches all of them. Note that the 5f and 6f (FM7) is usually not engaged.
