Installation

The package contains the folder JCself with the program, a start file each for Windows and Mac, and the manual. In full detail with all notes: Manual › Installation.

Windows

  1. Install Java 8 or newer if it is missing, for example Eclipse Temurin, free of charge.
  2. Unzip jcself-gipfel-en.zip and put the folder JCself somewhere you are allowed to write, such as “Documents”.
  3. Start JCself by double-clicking JCself-start.bat.
  4. For the Csound sounds, also install Csound (recommended). For the orchestral instruments – piccolo, flute, clarinet, horn, trombone, timpani, bass drum, violin, cello – you also need the unpacked folder of the free VSCO 2 Community Edition, see Manual › Instruments.

Mac

JCself has not yet been tested on the Mac. We welcome feedback (contact).

  1. Install Java 8 or newer, for example Eclipse Temurin as a .pkg (Apple silicon: aarch64, Intel: x64).
  2. Unzip jcself-gipfel-en.zip and put the folder JCself in “Documents”, for example.
  3. Start JCself by double-clicking JCself-start.command. If macOS stops the file the first time: right-click › “Open”, or choose “Open Anyway” under “System Settings › Privacy & Security”.
  4. For the Csound sounds, also install Csound for macOS.

Older version

The Gipfel version replaces the earlier package jcself.zip with the folder PHS. Both can exist side by side. If you put your old jcself.sav into the new folder JCself before the first start, JCself takes over its settings.
