I wrote this small program in Max/MSP, to explore a rhythmical concept i call Wohl Temperiertes Phrasier Apparat, which is about "unequal" or "phrased" microtime,
as in swinging 8-notes, gnawan triplets or so-called brazilian 16-notes. You can download it here. If you don't have Max/MSP installed, you can download the free Max Runtime from Cycling'74.

As the concept is quite unusual, here is a little help file to explain how the program works:

I Settings

1. Start/Stop step sequencers, also works pressing the <space bar> key

2. set tempo

3. toggle metronome on/off

4. select tempo change mode when you change microtime (see II microtime):
- with <tuplets> selected, the tempo remains the same
- with <rhythm modulation> selected, the program does a rhythm modulation, where the microtime remains the same

you must click that button and set audio on, otherwise the program won't work

6. set metronome's midichannel

7. set metronome's midi note

8. select your midiout device (example for mac users: AU DLS Synth)




II Step Sequencers

1. Set program change for sequencer 1

2. Set midi channel for sequencer 1 (default is channel 10 for drums part)

3. Set sequencer 1 velocity, will apply to every note played by sequencer 1)

4. Clear all notes in sequencer 1

5. Presets. store and recall everything in sequencer 1 and 2 + microtime settings (see III microtime)
shift-click to store, click to recall

6. midi notes mapping for sequencer 1

7. Set program change for sequencer 2

8. Set midi channel for sequencer 2

9. Set sequencer 2 velocity, will apply to every note played by sequencer 2)

10. Clear all notes in sequencer 2

11. Set loop range for sequencer 1. shift-click to alter only start or end point

12. Step sequencer. the steps value is set by the settings in section III microtime




III Microtime

1. Set microtime by clicking on the graphics. The exact shape of the tuplet selected will depend on the phrasing bar position (3.)

2. Create your own microtime shape. In order to understand this, see how it changes when you select different tuplets by clicking on the graphics (1.).

3. phrasing bar. the core of this program, and of the wtpa rhythmical concept
- when positioned to the left, the selected tuplet (1.) is "straight", as in the top part of the graphic
- when positioned to the right, the tuplet is phrased as the pattern in the lower part of the graphic
- anywhere in between the tuplet will be phrased in between. The phrasing bar actually sets the amount of the "pattern feel" you want the tuplet to have.

4. Presets. you can store and recall your own microtime shapes, created with (2.)
shift-click to store, click to recall


enjoy :-)
