From af057f48f833744b9d20eb536e220b6df247f7e7 Mon Sep 17 00:00:00 2001 From: Harald Eilertsen Date: Mon, 7 Dec 2020 12:50:00 +0100 Subject: Begin parsing of Arrangement1 chunk. This is the meat of the file, and the majority of the data. Don't expect this to be trivial, or how much of it I really need to understand.
