I attach two jconvolver config templates that will allow using the reverbs provided in the Hybridreverb database with jconvolver. BTW, Christian Borss' convolution processor is really very well designed. It uses some clever tricks to optimise the 2x2 and 2x4 cases with all convolutions having equal length. Zita-convolver can't use such tricks as it is meant to be general-purpose.
