(replying to myself)

this is only an issue with readsf~.
An [unpack] with 120 arguments and outlets works and saves fine.
Seems to be sth. within readsf~.
Initiating that object as [readsf~ 120] does not give an error msg. But 
is seems it is only created with 64 outlets. The multichannel-wav format 
seems to allow for more channels than that, i was able to create a file 
without errors, with its channels getting displayed in audacity (before 
that software gracefully crashes)
