Level of effect2 send, in percentage (chorus in Cakewalk sfz).
Effects handling varies across SFZ versions. In SFZ v1 only effect1 and effect2 opcodes were available and only at ‹region› level. In SFZ v2 the ‹effect› header was added, and effect3 and effect4. ARIA uses the effect header as well, with the MDA effects built in and the possibility to support vendor-specific effects as well.
