I'm not familiar with eTrigger, but a bit of googling led me to etrigger.net, which has a $79 download. Is this what you're referring to? I'm interested b/c I'm attempting to get HH control working with SSD on a PC. I tried the MidiYoke/eDrum monitor trick, which worked, but eDrum monitor slows my system down after about 2 minutes of use. Is there a "lite" version of eTrigger or anything (that won't expire after the trial period is over)?
