Filtergraph/ preset emergency!

February 16, 2011 | 8:20 am

Hi all,
I am a student due to hand in a series of max patches today!!
One of my patches is a straightforward feedback delay patch with presets.
I then have to extend this to include a filtergraph.
The problem is late last night I realised that selecting the presets makes the filtergraph behave erratically (one of the bands disappears out of visible range).
I connected the ‘exclude from presets’ outlet to each of the used inlets on the filtergraph. But this does not seem to sole the problem.
Does anyone have any suggestions?
Thanks for your time everyone..

You can only exclude _all_ of filtergraph’s attributes from the preset object.
To do this connect [preset]‘s exclude outlet to [filtergraph]‘s first inlet.

If you include/exclude objects _after_ having already stored presets you need to update all presets. Simply recall and store each of them.

You can also change filtergraph’s parameters in the inspector window.
If you have more than one filter, change "Currently Selected Filter" to the filter number.
Then reopen (!) the inspector window and change Frequency, Q, …
Otherwise, the filter parameters won’t get updated.
