Re: [sc-users] Scope question

[Scott Wilson <sdwilson@xxxxxxxxxxxx>]

With the internal server, you can do Server.scope in SC3. This will pop open a window and all the Buffer stuff, node allocation etc. is taken care of for you. The arguments are numChannels, startingChannel, bufsize, but for most cases the default works.

Again, this only works with the internal server.
