This is a tiny introduction to me, Eric, for scratch day.

conductomatic v4

this doesn't seem to be working correctly on the web right now- download to check it out. This version of the conductomatic was created during a jam session, following the first live performance which used version 2 (see that version for a description: http://scratch.mit.edu/projects/ericr/388671 ). The basic rules are the same as before: you improvise repeating patterns, and change your pattern at the moment a vertical line reaches "now." In this version there are also three different colors. When a line arrives, the background color changes. You are supposed to remember the pattern that you played, for example, on blue, so that when blue comes again, you play the same thing. And when orange comes again, you play your orange pattern. The "next" box shows the color coming next (like the thing showing the next block in tetris). It's a challenge for the memory- three seemed like the most different colors we could use comfortably, at least on the first few tries.

conductomatic v2

This scratch project was used, less than an hour after its completion, in perhaps the world's first live performance of improvised music conducted by a scratch project. We played a short set of several three minute "pieces," played by different groupings of a pianist, drummer, saxophonist, clarinetist, and trombonist (me). I pressed the start button at the beginning of each piece, and we would wait for the first vertical line to cross "now." At that moment, everyone would start improvising a repeating pattern, melody, texture, silence, sound, or whatever, trying to listen and lock in with each other. When the next vertical line reached the "now," we had to suddenly change to playing something different. The dotted lines mean an optional change. The amounts of time between each line's arrival are randomly chosen from a list of fibonacci numbers. After 3 minutes, "the end" arrived.

conductomatic v1

This is a first try at building an automatic conductor for improvising musicians. It simply displays vertical lines, which move across the screen at random intervals. When the line arrives at "now," the musicians are supposed to change what they are doing. The rest of the time, they improvise repeating patterns or grooves. The solid line means everyone has to change; dotted line means it is optional. The sliders let you change a few parameters. the duration divisor lets you make the durations between lines faster (the durations are actually chosen from a list, and they are meant to be used in performance with a divisor of one). The movement speed is just the speed of the lines. The dotted percentage controls how often the line is dotted versus solid. Press the start button to begin.

Bloom Tribute 3

Click to play notes. The notes repeat in a loop, gradually fading. Then they return, slightly changed.

Tribute to Bloom 2

This is my tribute to Bloom, an iPhone app I really like. Here's its website: www.generativemusic.com Just click on the stage to play notes. They will repeat in a loop, slowly fading out. Relax and enjoy!

Auto-Mosaic2

This is an automatic mosaic generator. It's based on craftcomputing's project- I was wondering if it would be possible to make a version that builds a mosaic based on an image. The result is a bit like using the "pixel effect" block but with a fixed set of colors. The stamper sprite checks the background color to see if it's touching one of four colors, then switches to a square costume of that exact color and stamps it.

hugo and friends

this project was uploaded as part of a demo- it uses the "loudness" sensor block, so it will only work when downloaded.

happy b-day mitch!
