triggered envelope for biquad

February 5, 2008 | 1:49 am

Haven’t touched max/msp for a while and it feels like I forgot a bunch of stuff :P

If I want to make envelopes I can trigger to do smooth filter sweeps and I use the Function object and biquad, what else should I use?

A bang will trigger the Function object output in line format. I could use a line~ object and then use number~ to convert it to a floating point value but then I need to convert it to logarithmic values.

Feels like I am forgetting an easier way to do this. Any tips?

All I want is to send a bang to the function object and then it will adjust filter cutoff based on the functions values over the domains duration.

thanks!

If your envelope requirements are simple, there’s adsr~

As you want to be enving frequency or q, rather then the a-coefficient, you will be needing the filtercoeff~ object as well. Log values are for instance produced by the mtof object.

Hmmm… I thought that adsr~ was a standard MSP object. You might want
to look on maxobjects.com
