Have noticed this morning that with the Steinway Grand in JABB – after updating to KP2 – the sound of the Bb below middle C is noticeably different from that of any of the other notes surrounding it when hit with high velocity (strong attack). It has a very metallic ringing to it, which is absent (as it should be) from all the other notes when struck similarly. Would appreciate if you can verify this on your end. I've compared it here with the GPO Steinway (also after updating to KP2), and thankfully that problem is not evident at all on the GPO Steinway. On the JABB Steinway, however, it is really quite annoying. I'm sure you'd agree that the response of all the keys across the keyboard should be similar. Don't recall this being a problem with JABB in KP1. In any case, hope you can correct this soon. Thanks.
