You're using a class variable, not a class instance variable. Class variables also need to be initialized when created.

A class variable is shared among all classes and subclasses, even its own class construction. Try doubling your code:
@ylist=Destination.new("")
%w[W A S H I N G T O N].each{|l ...

Thanks for the clarification tulamide. :D

I sort of expected all DAWs to respond to all possible dialogue with plugins. And if the plugin doesn’t offer some information, I would have expected the DAW to set a default. Goes to show how expectations can lead to disappointment!
Oh, another slip I ...

I wouldn't even mind the manual way (micro view for 3rd party plugins only exist since the last update in S1), if there were a way to save such settings. But there isn't, and so this work to setup a switch is only available in the current project. I know without even being at that point yet, that I ...

I did some searching on Google and didn’t find a way to visualise a float automation as a switch in Reaper. I’m impressed that it’s possible in Studio One! Or maybe it’s a common feature in many DAWs but not Reaper. Dunno.

The thing that caught my eye was that S1User said other plugins showed ...

Use math! You're multiplying a number, so 1 is unchanged and therefore 0 dB.

The formula for dBFS is 20 * log10(abs(value))

That tells you, that for -12 dB to +12 dB, the range has to be 0.25 to 4 (a quarter to a quadruple). Since it is a logarithmic scale, I would use the actual dB values for the ...

As far as I know, only Presonus' own plugins come preconfigured for the micro view!
You're welcome, have fun with your plugin

Switches from Flowstone don't show up as switches in my DAW, in the automation system. Is this something I can change in the preset manager? See the image below where the switch from FS on the second plugin shows up as a slider, and can't be linked to a button in the automation system.

Is there a ...

If anyone here can come up with a more convincing physical algorithm, I would LOVE to see it!
I don't have anything useful to say or add, but this:

In a complex (chaotic) system like a Mark Tree, you can only go OOP. Instead of trying to keep track on why and where which pipes collide, you define ...

Very interesting.
I might not have the full picture, but could the issue be related to other programs on the PC hogging memory? I imagine that Windows should prevent that but I’m no expert on such things.
Your instincts are correct. The issue is not related to other programs. It is the plugin ...

One notable thing is that after playing for more than an hour one synth stops responding to knob changes and other things.
This is an important detail to know! My brain is already warming up. Some background:
At the heart of programming is memory allocation. Every programming language has a stack ...
