i see. i was thinking, that oyu might have only very few file reading
objects in your patch, that it would be easy enough to adapt your patch
in a manner, that it loads all presets in advance. but if you are using
an ready-made, more complex system, then this probably won't be an easy
thing to do.
nice to hear, that it works with a ramdisk. i never used a ramdisk
myself and i didn't know, that it would be so easy to setup.
