OSC_TUNE.PRG is a program which determines the current tuning of the two oscillators of the Chroma Polaris. With any mouse click (left mouse button) the program newly determines and indicates the tuning.

The program runs on Atari 1040 ST. The Polaris and the ST have to be connected with two cables for Midi out and Midi in.

You may terminate the program by pressing CONTROL-SHIFT-ALTERNATE simultaneously, and then click the left mouse button.

The program runs on my Atari ST and with my Chroma Polaris well and without any harm. But please be aware that I can't give any guarantee that it works on any other system as well and also without harm.
