This is really simple. Basically just download the project files, load them into Flowstone, and see if they mess up the way I describe.
First Test: Download this, open in Flowstone. IMPORTANT: Make sure you have Fruity Limiter on the master track and that you've turned your volume down low!
Now make sure nothing is selected (click inside the FS interface), and then simply press the delete key. This will probably spit out an infinite signal which will slam into the limiter and make an unpleasant buzzing sound. If not, try disconnecting and reconnecting some wires a couple times. If still nothing happens, cool, just let me know.
Second Test: Download this, open in Flowstone. This one shouldn't make any sound. You'll see towards the bottom a "mono readout" and a float value attached to a M2F. The value of both of these will probably show '20.' Now simply connect the float on the left ('0') to the "Frequency" input on the middle module. The two aforementioned values will probably go to '0.' Disconnect it again and they'll probably go back to '20.' If not, let me know!
I'm using FL 11.0.2 with Flowstone 3.0.2, so if you're using a different version it might be helpful to let me know.
Thanks a bunch!!
