Another possibility is that instead of using the Oticon proprietary fitting formula, your HCP might have chosen one of the standard fitting rationales in the General for you. These standard rationales are known to emphasize sharper frequencies in order to help focus on better speech understanding, but that might cause a detrimental effect on boosting up the highs for the violin sound too much.
So just make sure that the VAC+ Oticon rationale is used to avoid this possible side effect, and if it’s confirmed that it’s the VAC+ in the General program, make a copy of it to a customized music program for you, turn off all the special processing as mentioned in the previous post, then go to the Fine Tuning section and judiciously turn down the gain values in the high frequency channels in appropriate places to tone down the high overdrives that you hear with your violin.
Assuming that you only find it sounding bad on the highs for when playing the violin, but it sounds OK overall for normal use, then apply the high frequency gain reduction to the custom music program only. But if you find it helpful to reduce the highs for normal non-violin use as well, then you can ask your HCP to apply the high frequency gain reductions to the General program 1 as well.
Sometimes, playing the violin might have hit a resonant frequency of some sort somewhere in the high range for the whole Oticon Intent setup, but it just doesn’t happen on the Widex setup by luck. This might be the case if you find that the overall use of the Oticon Intent aids is OK, just bad only when you play the violin.
