Do you have sample patch for this? cheers, Dario PS: your work Egregore is fantastic 2017-02-10 12:00 GMT+01:00 <[email protected]>: > Send GEM-dev mailing list submissions to > [email protected] > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.puredata.info/listinfo/gem-dev > or, via email, send a message with subject or body 'help' to > [email protected] > > You can reach the person managing the list at > [email protected] > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of GEM-dev digest..." > > Today's Topics: > > 1.
