Hi hope it's not too late to revive this... I just tried the trial version of Simhaptic, and I think I'd buy it except.... With SimShaker I can get up to 6 channels. I currently have 4 subwoofer boards connected to a usb soundcard. And I have 2 transducers on the left and right of my chair, as well as smaller pucks on my left pedal, right pedal, throttle and stick. Run through 4 separate channels, left and right. I couldn't figure out how to get this to work in SimHaptic all I could get was 2. Thanks for any help.
