Not often, but meets. At import instrument from SF2, all samples have it Global volume = 4. It is necessary to correct manually on 64. I do not know, it is error OMPT or SF2. Meets, both in single SF2, and in multibanks.
In multibanks happens 5-10 instruments Global volume = 4, and the others - it is normal.
