Render Selection To Sample

I was just wondering …I am using the render selection to sample function quit alot …especcialy on (cpu hungry) vst 's …But I wonder if I render the part like a dozen times or so ( adding new effects and stuff ) is there gonna be a loss of quality on the rendered sample ?Or can you render the selection as many times as you want without losing quality ?

Hardly any loss.
Renoise renders the selection to 32bit samples. So you should not worry :)
It’s then more about what different vst’s might do to the quality of the sample.

However if you do a lot of pitching on the samples between renderings, then the resample and interpolation can be better if you render ‘offline’ (render to disk option) and use a better interpolation algorithm.
