Warning: Weird outdated Java software ahead!
I was digging around on an old flash drive and found many interesting lost things. First, the old Extratone Girlfriend software I made some years ago. It is veryyyy crudely made. Basically just an experiment, as normal DAWs like FL Studio and LMMS clearly werent made for XTRTN. You are much better off using VCV Rack - but I hadn't heard of VCV Rack at the time. Was VCV even a thing then? I don't know.🤷 Download.
Btw, I believe DZKYIN has made a few tracks using entirely XTRTNGF in his Experimentatone series.
