Je Cherches Un Sequenceur Midi Orienté Live Options

[chabb]

Je cherche un sequenceur midi tournant sous Mac OS X (10.2.8 ou 10.3) orienté live pour jouer avec d'autre musicien (batteur, bassiste, guitariste)

Pour l'instant je dispose du sequenceur integré au sampler K 2000 KURZWEIL qui est une petite merveille à part le fait que l'edition en est un peu delicate. et que je suis arrivé au bout de sa memoire (dont l'augmentation est trés chère)
Ce sequenceur permet de programmer des patterns qui peuvent eux même devenir des Songs incluants d'autres patterns.
Ils peuvent être lues en boucle un nombre de fois programmable, ou peuvent s'arreter à la fin du pattern, ou peuvent être enchainé à un autre pattern afin de demmarer dés que le precedent à fini. Ceci autorise donc la lecture lineaire de plusieurs patterns les uns derriere les autres, un peu comme Cubase ou Logic.

Tous les patterns inclus dans ces songs peuvent egalement et c'est le point qui m'interresse, être declenché par un n° de note issue d'un clavier midi.(ou par n'importe quel controleur midi)
Je peux donc programmer une song dont chaque pattern sera declenché manuellement en live au moment decissif (par ex: debut du couplet, debut du refrain, intro, extro, intermede...) avec des pauses possible au milieu et la possibilité de laisser les autres musiciens improviser le temps qu'ils veulent sans être enfermer par une timeline lineaire et et non modifiable en temps réèl.

Tous le logiciel sequenceurs midi que je trouve sur internet sont des sequenceurs lineaires. On programme des patterns les uns derrieres les autres sur des piste, on appui sur Play et on attends que ca passe sans avoir vraiment de controle Live sur l'enchainement de ces patterns.

Je connais bien aussi les sequenceurs du type MPC AKAI ou Roland ou Emu...qui permettent parfois cet interactivité Live, mais je prefererai utiliser mon PowerBook.

quelqu'un connais-t-il ce genre de soft ?

merci.

Je viens de trouver çà dans l'aide Logic ...

The Environment > Environment Objects > Touch Tracks



Touch Tracks turns Logic into an interactive live sequencer. A touch tracks object allows you to trigger MIDI sequences or folders with single notes.



You can not use Touch Tracks to trigger audio. In the following section, any references to sequences means folders as well.



To create a Touch Tracks object, drag a sequence or folder from the Arrange window into the Environment window or select New > Touch Tracks. To use a Touch Tracks object, simply assign it to an Arrange window track, or put it anywhere in the MIDI signal path.



Here are some things to remember:
Only the Touch Tracks input has meaning-the trigger notes must appear here. Although there is an output triangle, it has no meaning-no events ever appear here.

Sequences triggered by Touch Tracks play exactly as they would from the Arrange window. In particular, they play back through the instruments assigned to their tracks.

Logic's Transport must be running for Touch Tracks to work.






The Touch Tracks Window




You open the Touch Tracks window by double-clicking on the the Touch Tracks object. This window is set up similarly to the mapped instrument window-the input note is selected using the keyboard on the left, and the output sequence assignment and parameters are set in the columns of the corresponding row.




Sequence Note Assignment




Dragging a sequence into the Environment initializes a Touch Tracks object, so that initially all notes trigger this sequence. (Middle C plays it at its original pitch, and all other notes transpose it relative to middle C.)



In the Input column, you can see the input notes, and to the right, in the Sequence/Folder column, the names of the assigned sequences or folders. On the vertical keyboard to the left, you can select individual notes or whole pitch ranges, by grabbing and dragging. If you then drag a sequence from the Arrange window, it will only be assigned to the selected note(s).



Remember that with the following parameters, all settings also apply to multiple selections.



A vertical gray line means that the setting is the same as the line above. If you change a vertical gray line that is above another vertical gray line, the lower one will change to display its previous value, (i.e. it will no longer be the same as the line above.)




Group




To the left of the sequence name is the group column. Groups work the same way as they do in the Hyper Editor-when you trigger a sequence, any other sequences in the same group that were playing will stop.



The off setting means that the sequence is not assigned to any group.




Transposition




When you drag a sequence to a key in the Touch Tracks window, that key triggers the sequence at its original pitch (i.e. without transposition). If you want the sequence transposed, you can set the amount in the Trp column (± 99 semitones).



If a key range is selected when you drag the sequence to the Touch Tracks window, then incremental transpositions will automatically be set for adjacent keys.
When you create a Touch Tracks object by dragging a sequence into the Environment, C3 triggers the sequence at its normal pitch, and all other keys trigger it transposed relative to C3.




Velocity Sensitivity




In the Velocity column, you can set how much the velocity values of the played sequences are affected by the velocity value of the trigger note: by 100% (meaning a lot), 50% (meaning a little) or off (meaning not at all).




Trigger Modes




The Trigger column sets how sequence playback is handled:



- Multi
Playing the trigger note starts the sequence. Playing it again starts the sequence again, without stopping the original version.



- Single
Playing the trigger note once starts the sequence. Playing it again stops playback, and starts the sequence over.



- Gate
The sequence plays until the trigger note is released (or until the sequence ends).



- Gate Loop
The sequence loops until the trigger note is released.



- Toggle
Playing the trigger note starts the sequence. Playing it again stops playback.



- Toggle Loop
Playing the trigger note starts the sequence looping. Playing it again stops playback.




Start




In this column you can quantize how sequences start and stop. Free means there is no quantization. The next 1/16, 1/4 or 1/1 settings start or stop the sequence at the next 1/16 or 1/4 note or at the start of the next bar, after a trigger note is input.




Delay




In this column you can assign the sequence a delay. As in the sequence parameter box, the delay is set on the right side of the column in ticks, or on the left side in note values.



You can use Delay and Start together to make sequences start at any position in the measure. (e.g. Set Start to 1/1 and set Delay to 480 ticks to start playback at the second 8th note in the measure.)
