I should clarify 'noise'. I don't mean pink / white etc. I mean off specific pitch and sequences. For me this generally happens by overloading modulation to the point of breakup.

I use the Echoz and the A-143-4 because I already own them, like them and don't have unlimited budget to spend. Morphagene looks good but I'd really want to try one out for a time before committing to £500

Cosmix has always been really handy as being able to mix sources and mute immediately is very useful in love performacces. It also has the drive feature which significantly warms up and boosts the output sound

I'll check out Nautilus and mimephon :-)
