Nice little Synth Module But worry with OS updates!

I bought this App while the OS was Maverick and it worked fine and actually wrote a few songs until I updated the OS to El Capitan. The app became useless. Months have passed and finally an update for the synth app. I was back in business. Now there is another OS update so, here I go and hope it does not kill this little nice app.
