Jon Grove J-Scope free oscilloscope plugin released


Jon Grove has released J-Scope, an oscilloscope plug-in for Windows.

Whilst experimenting with writing a VST synthesizer plugin, I found I needed an oscilloscope whose behaviour I understood. The synth plugin has not yet made it to a state where I feel it’s worth releasing, but I think the oscilloscope may be useful to someone.

I’ve tried to make it fairly similar to a real oscilloscope, although the fact that the waveform is fed to it in bursts which don’t necessarily synchronise with the computer’s display refresh rate or with the oscilloscope’s sweep rate makes it hard to accurately model a real screen.
