This piece uses two different patches (on the same computer) :

• one for polyrythm machine (called PRTM),
• and another patch for electronic treatments. This second patch is the master patch, and control the other via local OSC.

Audio is sent and received via soundcard loopback or via your loopback solution of choice from one patch to another.

Audio from microphones is sent to computers through the mixing desk. A midi keyboard on stage is used to trigger events. Master and Spare computers receive the same inputs

Initialization routine

• Open patch in one Max8 instance /AntPolyRyt-Score/AntePolytRyt/AntePolytRyt.maxproj
• Click "ALL.INIT bang" button
• start DSP

• Open patch in a second Max8 instance /Tutti-Main/PATCH_TUTTI_2016_MAX7/Tutti-MASTER-1e.maxpat
• Check in "p BUFFERS" that media are loaded
• if not load them (located in Tutti-Main/SOUND)
• click RESET button
• start DSP
• click RESET button again
• Load score to follow : Tutti.asco
• configure midi keyboard reception and activate midi reception (blinking button in (6) )

At this point, the patch is ready and is waiting the first midi keyboard note to start. the main patch control the PTRM via local OSC

Mix and control is achieved via Mira web or LEMUR on Ipad. open and edit patcher "p MIDI/OSC". Interface for Lemur software is in /Tutti-Main/PATCH_TUTTI_2016_MAX7/LEMUR/lemur1e.jzml

PTRM Patch :


Controled by the main patch and Antescofo

Antescofo :

Antescofo is used to manage and recall effects preset, like an electronic score. Open _/Tutti-Main/PATCH_TUTTI_2016_MAX7/ANTESCOFO/_Tutti.asco.txt in a text editor to see or modify the score. All events are triggered by MIDI keyboard.
To start directly to an event, click RESET, and select the event you want to jump to. Antescofo will wait a "next_event" or the corresponding note from MIDI keyboard to launch the wanted event.

(FYI, "Jump to" launch all events from the beginning of the score to the previous event you choose.)

Click button "repeat" to repeat the same event.

Click button "next_label" to go to the next event (or to trigger event choosen with umenu "Go to Cues"

Click red button "RESET" to inialize all the patch.
