Filter Design

[Allan]

For my Synth(its a Uni. project), my lecturer has suggested these filters:

MF10
MF5
LMF100
LMF100C1
LTC1068C

Should I use any of these or are they not suitable for this purpose?
If not any suggestions for readily available alternatives?

Also How many filter banks should i use/are commonly used?  Do i need a
number of diffrent types i.e low,high and band pass?

Cheers

Allan
