ok I hope my next question will not be so dum... dum dum. dum.
Im reading up on filters and see that IIR and FIR filters are differentiated by 'feedback' (re:
DSP GURUs FAQ)
Quote:
1.3 What is the alternative to IIR filters?
DSP filters can also be "Finite Impulse Response" (FIR). FIR filters do not use feedback, so for a FIR filter with N coefficients, the output always becomes zero after putting in N samples of an impulse response.

Am I to understand this 'feedback' described is much like 'feedback' for a 'traditional' delay/reverb.
In other words - if I re-send output of one samples filter operation back into tram - and use that instead of a 'non-fed-back' but 'delayed' value - I would now have an IIR filter.
Other than coefficients - is that the only 'programming' consideration I need to be aware of?
In other words - Can I tell by the lack of such feedback operation in existing KX filter plugins - that they are FIR and not IIR? Or vice versa? (If there IS feedback - its definitly an IIR filter ??)
*hopes that made more sense , than me sounding dum*
Thanks,
Mark
