This product has been discontinued now, which is a shame because it's a remarkably versatile effects plugin that lets you do a lot of stuff and is very powerful in the way it can be triggered and modulated. It has a multitude of waveforms, four filters, delay and a rhythmic modulator thing for creating trance gate effects etc. One particularly interesting use is that you can stick it on your track's master bus with a ramp-up waveform and use that to modulate the gain in perfect tempo sync with your song; creating the house sucking/pumping effect absolutely perfectly. I wonder if Antares will ever reboot the line and create a new version? It seems they're too busy playing catchup with Melodyne at the moment, and selling mini versions of auto-tune designed explicitly to recreate the Cher effect that looks like it will never go away! I guess if Filter isn't ever relaunched, there are alternatives such as Fabfilter's Volcano 2 but it doesn't have the charm of this old product by Antares. I guess if they don't ever relaunch then technically, eventually it will become abandonware. Make of that what you will!
