VerbPRO Technical specifications : -True stereo, with a slightly different algorithm for the left and right channels to enhance the stereo image result.¿ -Smooth truly stereo, each channel is processed separately.¿ -ROOM/PLATE/LARGE/CATHEDRAL/GARAGE/METAL/VINTAGE etc more than 20 type of reverbs.¿ -You can change the Reverberation time, the Damping, the pre-delay and the reverb color from the front panel. -The Diffusion, and Density button can change the reflections to simulate warm reverb, metallic reverb, wood rooms, or delay reverbs. -GATE effects for doing the typical "Phil Collins" gated reverb effects. Great on heavy drums. -a 4 points parametric graphical equalization to change the reverb color. -low pass filters, high pass filters. -pass band filter with Q. -access to the reverb modelisation parameters. 8x2 comb filters and 3x2 allpass reverbators This feature add some very interesting and subtile effects to change the reverb sound and simulate hardware units. More parameters will be added soon such and the random walls -32 bit internal calculation power -uses only 1 DSP. - internal 32 bit calculation.
