Topic: Ambience Reverb
The Ambience Reverb (mentioned in the thread about the Garritan piano) has two piano reverb presets that sound good with PianoTeq: The Piano Body preset and the Piano Bright preset. The defualt settings may be a little too rich--you may want to bring down the Wet a little and raise the Dry. (For some reason, all of the presets have this problem of being too wet by default.
Notice that clicking on Variation at the bottom of the interface will give you slight variations on these presets. If you find one that sounds particularly good, you can then save it as fxp for future loading.
