The synthesizer is controlled by a JAM STAPL program executed by the JAM STAPL Player. The reference divisor (m) and VCO output frequency (f) are specified using command line parameters:
D:\JAM>jam -df=19876543 Data.jam
D:\JAM>jam -dm=104 -df=19001000 Data.jam
jam.exe JAM STAPL Player version 2.3
-dm= Define variable m (default: 100)
-df= Define variable f
