Quadraverb Patches

The “Quads” longevity is a testament to its outstanding sound quality and highly editable effects.
The Quadraverb can squeeze out an awesome amount of sonic bliss in the hands of the right programmer.
Editting may be done via the frontpanel or via midi.

Quadraverb Plus, GT, Q2, Q20

Charlie Hall has developed patch sets for these Quadraverb units and some others over the years.

The sounds are very close to the original sounds of many vintage echo tape units from the past.

Compared with modern digital fx boxes, the sounds are warm and very close to reallity

Midi Interface

To connect the Quadraverb to the PC, a Roland/Edirol UM-One Mk2 or equivalent midi interface is needed

Many cheap units fail to do the job!
