Testing a Bug - Help Please! (Quick & Easy)

[Perfect Human Interface]

Hey there, I need a hand testing out a couple bugs if you could spare a minute to do so.

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:

Evil Buzz Noise.fsm

(31.21 KiB) Downloaded 800 times

Download this, open in Flowstone. IMPORTANT: Make sure you have a limiter in place 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 (triggers a recompile). This MAY 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.
EDIT: I'm not sure what environment people normally use FS in or whether some just run it standalone, but alternatively you could just connect a "mono readout" to the output of this module and see if it shows a NaN (should read "-1.#IND" or something like that), and possibly turn your speakers off for safety.

Second Test:

wireless 20 bug.fsm

(5.93 KiB) Downloaded 813 times

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 either show '20' or '0.' Now simply connect the float on the left ('0') to the "Frequency" input on the middle module. The two aforementioned values should go to '0.' Disconnect it again and they may go back to '20.' If not, let me know!

I'm using the FL version of Flowstone (3.0.2); if you're using a different version please let me know what.
Thanks a bunch!!

You are writing values to an input, that's causing troubles. Here is an excerpt:

Code: Select all

streamin freq;      // frequency of input (Hz)
...
freq = max(freq,20);   // no less than 20 Hz
T0 = samplerate/freq;


Never write to an input! Do it with temporary variables when required, or just inline like this:

Code: Select all

streamin freq;      // frequency of input (Hz)
...
T0 = samplerate/max(freq,20);

Ouch! That's my fault. Thanks MyCo, fixing that makes the "wireless 20 bug" disappear.
As to the "evil buzz noise", I haven't been able to see it here (FS 3.0.3).

Thank you!

So far, the people at the FL Studio forums seem to get the NaN bug (the "buzz noise"). Still looking for data points as to whether non FL Studio users get the same behavior.

Hi folks, giving this a bump because I still need at least one data point on whether the NaN bug (the "Evil Buzz Noise" one) shows up on non-FL Studio versions of Flowstone. TIA
