Freq shift~ bug /
I think I discoverd a serious bug where the frequency shifter outputs audio without any input
Easy Steps to reproduce
-Create saw~
-Route saw into live gain~ ( let's call this gain A ) into ezdac~
-Create freqshift~
-Route ( same ) saw~ into freqshift~ and create a new livegain~ ( let's call this one B )
-Route freqshift into livegain~ "B" into ezdac~
-Apply freqshift value to freqshift~
-Enable both live gain mixers and now disconnect saw~ from freqshift~ ( while audio is running ) and also mute livegain 'A' ( dry saw~ ) .
Result : freqshift~ still outputs a signal , and what 's even more weird , altering the frequency of the saw~ is reflected in the output of freqshift ( while gain A is totally muted )
There is some kind of invisble connection and it sounds pretty horrible .
Sounds like a buffer issue
Nice find. There's some weird stuff going on perhaps related to the right outlet (negative frequency shift) of freqshift~.
Steps to repro:
Open freqshift~.maxhelp
Set the source file to loop (this just helps in hearing the issue)
Turn on audio
Start the 'demosound'
Change the frequency shift so you can hear it (this is optional)
Unlock the patch
Select and delete the cable between the Source: bpatcher and the freqshift~ object
Expected result: sound stops (no longer heard)
Actual result: sound continues but is 'distorted'
Continuing:
Select and delete the cable between the right outlet of the freqshift~ object and the gate~ object
Expected result: presumably 'distorted' sound would continue
Actual result: sound stops!
Note: using the 'clear' message to freqshift~ while the sound source is disconnected doesn't seem to do anything. I was thinking it would clear the buffer but apparently it does not.
clear
Clears sample memory (in case the filter is blown up).
Thank you for the clear report. I am able to reproduce and we'll work on a fix for a future version.
