Slew limiter in Max

Setting the  cutoff frequency of a lowpass filter to sub audio frequencies creates a portamento effect when used with control signals.

This Max example was adapted from a Pd jet engine patch by Andy Farnell in “Designing Sound”. Its used as an inertial delay, or portamento to ramp up and down the pitch of the engine.

The LPF needs to be extremely low frequency.

working with audio samples in Max

notes

  • Start with MSP tutorial 13: record and play samples
  • use help file for [play~] object
  • [wave~] plays a buffer using a phasor
  • User [phasor~] to repeat audio sample,
  • [groove~] is good for sustained loops
  • tutorial 14 – is a great example of how to use numbers to work with sample data
  • tapin and tapout for delay
  • gizmo for pitch shift

Pd expr~ object

Helpful for pd->max conversions.

By Graham Wakefield, at the Cycling 74 forum

Hi all,

I’ve just coded up a signal rate version of expr (in the last hour, so
consider it beta!). I’ve named it expr~ since it should be pretty much
backwards compatible with expr~ object that used to be available.

Universal Binary, no Windows version yet (I don’t have a Windows box with
VS near me):

Enjoy!
