Hi Asmodis. I'm not too familiar with the Cells module, but if I remember correctly it's a sequencer that comes with the Nifty Case, right? I don't know if you have any other external gear for sequencing, but you may want to look into something that gives you a little more precise control over pitch/triggers/gates/etc. I know random works pretty well in generative ambient and drone stuff, but at some point you will probably want to impose some order and structure.
And, as far as random goes, the Wogglebug and Marbles do some similar things. Do you need both, or could that space be better utilized with something else (maybe a filter)? Just a few things to consider.
Have fun and good luck!
