DeepMind 12: Odd VCA behavior with curves



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.
