I think revisions of Linneleum were discussed here:
I briefly looked into the Linnoleum scripts and I found nothing about choking. Though in can be typically done really quickly. I’d say you put different hihats under different group opcodes and silence them each by the off_by opcode. Finally off_mode and off_time would be another interesting opcodes.
As far as I can see the keyswitched script only lets you chose between the Rev.2 and Rev.3 version.
