What do you mean by "hard"? Like complex transformations, or...?

Well, one purpose is to mix together some streams. I think I don't have to 
explain you how the reactable works.. :) so.. Like the mixing which has to be 
done in the sink... to get all synth-items together. 

All in all I have to admit that I'm more or less new to the DSP..  I 
understand the technics behind it and stuff,  but I cannot refer to deep 
knowledge. 

I understand that when transforming (like changing amplitudes in 
frequency-domain) errors occour when synthing again the signal. 

So.. what could called to be complex then...? Is mixing together some streams, 
or changing some frequencies amplitude be considered complex?

Or if I just want to build a resonant filter: Setting all amplitudes to zero. 
For, this is nothing "complex"... well..

But I also would appreciate some hints where I can read about this in detail. 
Unfortunately CLAM-Docs are bare informative about this all.
