This is an article culled from archive material, circa 1997.
Pretty much the first of the multi-effects boxes, featuring versatile
programming options and a respectable realtime control via MIDI with
irritating pressure-sensitive buttons on the front panel and a
syntax which could best be described as inconvenient. A firmware
upgrade converts a QuadraVerb into a QuadraVerb Plus
provides more algorithms, including tunable resonators and a one-shot
sampler. The upgrade is (or was) basically free, so most QuadraVerbs
circulating should already be Plusses.
The QuadraVerb is rather long in the tooth these days (having been
superceded by various other Alesis products, most obviously the
), although the UK Distributor Mafia still sells them
for $500 or so each. The sound quality is not stellar,
but the grainy sound quality has a certain charm and does have its uses.
Word of warning: the QuadraVerb has a "soft" MIDI Thru feature. I have
never come across a Soft Thru which worked properly. This one is no
exception. Place nothing downstream of it.
Major bummer: enormous inline power-brick with nonstandard
connectors. Alesis take pride in such details.
