I've had a Wasp filter for a few weeks and it's started behaving strangely. With the level control turned to full and all the other controls set to zero, listening to the LP output I would expect to hear nothing - but I now hear the input signal coming through clearly. Turning up the resonance seems to have no effect any more, and opening up the filter there is some timbre change but nothing like what I was getting before. Prior to this I had a few instances of unusual behaviour from the filter, in which the level would suddenly drop or increase. But now it doesn't seem to be behaving as a LP filter at all (when listening to the LP output). I have seen in various posts on the web that these filters can be unreliable - any thoughts?


I'm new to modular. Is an "active" mult the same as a "buffered" mult?


Thanks Lugia, that's very helpful.


Hi, I am new to modular and my first purchase has been an Arturia RackBrute 6U housing. Even with just a single module installed the unit is creating an annoying 1.5kHz tone, which is clearly apparent when monitoring and in audio recordings. I suspect that this is being generated by the Arturia power supply unit and must surely be a hardware fault. Has anyone else come across this? I have seen one or two comments on the Arturia forum about this and wondered if it was a well known problem in this community. Thanks!
