This week brings a number of new free effects for both Mac and Windows:
Mac OS X / Now in VST (previously AU-only): Expert Sleepers
has a Multitap Delay with filter and saturation, Phaser, Ping-Pong
delay, and a delay called Meringue that runs both forwards and
backwards. Simple, straightforward controls, but handy tools and you'll
find other free and shareware OS X goodies at the same site.
Windows VST gets a brand-new four-pole analog modeled Auto Filter by Kjaerhus Audio. This one looks near-perfect with full automation and syncable LFO, and clean, vintage-style controls.
