This version is a beta version to fix a small bug in the begining of the ODF code. This version allows you to save each ODF with a different name. The error was that all organs had the same name : MYCO 2013" Here are the lines: 08 890000 09 Myco Organ [Make Your Custom Organ] 10 Myco Organ 11 MYCO 2013 In the previous version of MYCO, all four lines remained the same. You need to change them for each organ definition by editing the Custom Organ Definition. The file name also needs to be modified (Myco Organ-(890000).CustomOrgan_Hauptwerk_xml). Without these changes, the generated full organ definition file is being overwritten by subsequent custom organs.
