I’ve made lots of max/msp and max for Live patches for myself and others. Some of these were part of a collaboration, others were tools people needed for their music and some were just for me. A few things I made:

PreshRingMod for Me - An oscillator based ring modulator with a series of 2 oscillator modulators for M4L. It’s the ring modulator I always wanted

Repeatadome for Tyondai Braxton - A looper that’s somewhat similar to an echoplex

Tiny Little Death for Matt Marks - Matt used this and a Trigger Finger to play backing tracks and control vocal FX parameters

Xylosynth for Shayna Dunkelman - A DSP host that Shayna uses with her Xylosynth (midi xylophone) and foot pedals. It saves and recalls presets for plug-in macros and mixes.

Pulcinella for Zeena Parkins - Playback and mangling of audio files for use with an Evolution UC16

Pipa for Bik Lee - 4 voice semi-random FM synth, filter, one-shot sampler, glitchy sampler, mixer, FX and preset saving/recall

Phalanx for me - An array of 12 simple selectable FX for max for Live that each have 2 knobs. Simple but lots of simple.

Head Turn for Ted Hearn - Play samples from your keyboard. As simple as it gets.

Unmutable for Tyondai Braxton - It takes midi notes in and only lets them pass through once for every x number of times in.

Zodiac Attack for Deviant Septet - This is for a piece I wrote based on the Stockhausen piece Tierkreis. Each player switches between a series of slow ostinatos and playing short phrases into a microphone feeding the max patch that records, mangles and replays their parts.
