Hi Dieter and thank you for the reply.

I can not be to certain to the accuracy of my monitoring of the sound - but, with the settings I mentioned above it is almost touching the -4dB level on my hardware mixer (with no extra gain) and roughly the same in my DAW.... so pretty loud!

I should have recorded a sample with audio input for comparison, but with lower frequency input the sound is fairly noticeable as the LFO cycles... even more so with higher frequencies as the sound is fairly low.... it makes a useful kick drum btw! ;)

I only had the filter for a short period before I sent for the replacement, but I am almost certain that it never behaved this way at first... it seems striking that the replacement would be the same.

Having said that; I have eight filters in my system - five of them being Doepfer and this is definitely one of my favorites - a wonderful smooth sound and I personally prefer its more ''darker'' tone compared to its nearest rival.


Best wishes
