Two demo patchers for this post: waveformGroove.maxpat and waveformGlitch.maxpat. Look at the waveformGroove patcher first. waveform~ The waveform~ object is a graphic editor for buffered audio. The easiest way to make use of waveform~ in a patcher is to copy and paste from the help file. This implementation is copied from the subpatcher for multi-channel…

Demo patcher: RecordNGroove.maxpat Today’s demo patcher is based on grooveplay, from the buffer~ and groove~ post. Some minor changes, before diving into the new stuff. The buffer~ object (in the green section) is getting audio from the record~ object. I’ve deleted the read messages. You can put them back in, of course. In the groove section…

I included the example patcher (grooveplay.maxpat) in the zipped soundfilepatcher archive from Monday. buffer~ Preliminary stuff first. buffer~ allows you to load a sound file into RAM. You can play it back with a number of objects, get information about it, etc., but it is in effect like sampler memory. The object takes arguments for…

I’ve zipped the example patcher, CtlnAssign, and a couple of sound files into one downloadable folder. sfplay~ MaxMSP has an excellent tutorial and help patchers. My example doesn’t try to recreate everything you can do with sfplay~. I’m focusing on basic playback, the loading of files, and how to create a useful start/stop mechanism with…

As indicated, this is a scaled-down post so that you have the demo patchers from class. To use the PolyAudioDemo.maxpat you also need to download SimpleSynthKeith~.maxpat and place both patchers in the same folder. Highlights The poly object The poly object takes incoming noteon and noteoff messages (note number and velocity), tracks them so as…
