 ## Filter order (type)
 
 You can also use the <ic>ftype</ic> method to change the filter type (order). There are two types by default, <ic>12db</ic> for a gentle slope or <ic>24db</ic> for a really steep filtering slope. The <ic>24db</ic> type is particularly useful for substractive synthesis if you are trying to emulate some of the Moog or Prophet sounds:
