Launching software components & playing back datastreams

The purpose of this entry is to provide a short video clip of a few simple playing techniques and the Datastream file that was generated by these techniques.  After watching the video and downloading the datastream file, you will want to play this file back.  By playing the file, you will be able to ‘emulate’ the t-stick gestures seen in the video.  Before playing back the file, you may want to review some set-up procedures that have already been posted on the workshops website.

Software setup for “power of one” – How to set up the t-stick and mapper and load mappings
Datastream record & playback – Description of patch for playing back t-stick gesture data
DOT Mapper – Introduction to the mapper (e.g.,  making mapping, loading, saving, etc.)

Software setup

Follow the instructions shown in the video, entitled Software setup for “power of one”.  You can open my programming for my piece, Everybody to the power of one, but later you will obviously want to open your own ‘performance patch’ and also your own synthesis (e.g., in Logic, Battery, Max/MSP).

To facilitate a move to your own programming, instead of opening my Power of one ‘performance patch’, open up the generic workshops performance patch, entitled workshop_performance.maxpat.

In the T-Stick Repository, go to:
MaxMSP Components/performance/workshop_performance.maxpat

This performance patch contains the t-stick programming and also my signal2midi patch for converting data from the t-stick into standard MIDI messages.  In addition, the performance patch allows you to call up an instance of DOTmapper in order to make, load and save your own mappings.  It also allows you to open an instance of Datastream for playing back (emulating) t-stick gesture data.  Click on “Mapper” and “Datatream” in to top righthand corner of the GUI.

In addition, you may eventually want to have more editing capabilities over the t-stick Max patch, in which case you will have to open up individual patches and initialise them, instead of opening up a ‘performance’ patch.  Contact me if you want to try this option.

Video and Datastream file

The main reason for posting this video, and accompanying datastream file, is to give you some material to work if you want to emulate t-stick gestures using my Datastream Max patch.  I hope you will be encouraged to send me your gesture ideas.  In turn, I can record the datastreams of these gestures and send them back to you to work with.

This short 35-second video clip illustrates a few simple playing techniques.  The playing techniques in the video are:

–  Framing and then fingering a couple of ‘notes’ with the right hand
–  Tilting
–  Releasing the ‘notes’

Crtl-click and “Save linked file…” the accompanying Datastream text file:
