Nice Graphics! I realize this is YACS-80 but the sound samples are very convincing. How much is the license? It's not clear on the web site.

It's good to have your own post about your product, but there was this one from before:

The sound is excellent. From what I can tell after matching the settings of the Brass 1+2 preset, this is a major improvement over the previous versions.

Never seen a commercial plugin not be code signed for apple. Pay the 99 bucks man, I don't want to have to quarantine software I buy.

The Unstable demo refuses to load in FL Studio 25.2.5, Windows 11: "There was a problem opening the plugin UNSTABLE for an unknown reason. Please make sure it was installed correctly."

As I already replied in the other thread, I checked it in FL Studio 25.2.5 and confirmed it works fine. Please make sure it was installed correctly - as FL Studio's very own message suggests, before publicly reporting a bug.

Yep this should be the norm.

I have no records of any purchase from you. Allowing unsigned software is a standard macOS setting that takes about 10 seconds. It's documented on the download page and on Apple's own support site. Plenty of indie plugins ship unsigned. If that's a dealbreaker for you, fair enough, but telling me how to spend money you never earned me isn't really how this works.

No, but it will affect how others perceive your brand in the end.

Again: unsigned plugins are very common among indie developers, hence instructions are on Apple's very own website. This is a non-issue. Let's move on.

You may think so, many others will disagree. You are reducing your possible revenue with your own cheapskating.

There are free and open source projects out there that have no problems in providing signed binaries. You have no excuse for this.

Thanks very much! Improvements are still ongoing, we have modeled the four preset cards and are adapting them fairly closely. However the unstable filter is different by design, as we wanted it to be”sing” a bit more. The original CS-80 doesn’t necessarily do a lot of self oscillation.
