kraken has become a dad now …( without being sarcastic )
About optimised for speed …;;hm .;
This reverb ( imho the best ou there ) uses the exact amount of cpu as convolver , an is also realtime …and sounds superior .
In the end …;al off of renoise effects are, sorry to say …inferior to even freeware stuff .
A bit sad , because they have potential ,.
I started a topic , charge more money for renoise , hire some seasoned dsp developers
