Thanks for your proposition! I'll have a closer look at it.

Maths was on my list, but couldn't manage to fit it in. I'm hesitating a lot between the Pico DSP and the Black Hole DSP which comes with more controls and effects.

What I like about the Dual ADSR are the extra options (EOD, cycle), but Maths seems to have similar options.

I don't know where you live, but here everywhere I look the Veils is 20 to 40€ cheaper than the Intellijel Quad!! :-P
