Hi,

I've noticed that the decay does not behave as expected when setting the decay curve to +50% (255). At the end of the decay period there is an extra hump right before the envelope enters the sustain phase. Can someone else confirm this? Is it a bug or is it just my DeepMind 12 that is acting up?

Steps to reproduce:
1. Create a default program
2. Set VCA sustain to 0
3. Set VCA decay curve to 50% (255)
4. Play a note and let it decay fully.

I've attached an audio example.

I use Logic X and have had this interface for a few months.  All of a sudden when I was trying to record some tracks, I was getting a digital frequency ringing that comes and goes as I test my input levels.  I have switched usb cords, I have made sure there are no other wires touching the interface.  I have tried switching out XLR and quarter inch input cables and they still give me this weird intermittent frequency buzzing sound.  When I try and record in Logic the buzzing sound was actually recorded and you can see the wave form of the noise.  Does this sound like an internal hardware malfunction in the interface?  Thanks for any help in advance.    

 I attached an audio sample of my snare drum but you will hear the high pitch frequency interfering with the track.
