For our project we are trying to create a normal timeline, where multiple curves are actually being controlled by one cursor. an illustration:
maybe it is possible to control the position of the other cursors, with the x location of the timeline-cursor?
would be a blast if this is easily possible 🙂
Well, we thought about this case but it’s not so easy (what about polyphony, when there are multiple y positions for a given x-position?).
But you can have a look at the example « Xenakis Metastaseis linear » that is very close to your question (thanks to the messages arguments collision_curve_id, collision_xPos, collision_yPos, collision_value_x and collision_value_y, cf documentation).
Hope it can help you!
thanks for the quick reply!
the example shows indeed a single timeline cursor 🙂 but now the different curves have the same mapping (because of the single cursor). Is it possible with osc to control other cursors with a timeline cursor?
Well Charlie, it is not possible with this version. Cursors works with their progression on a curve (so with time), not with absolute x or y-position (because of conceptual problems like polyphony…).
But if is juste a question of mapping, maybe you can make the mapping in your connected software, which are you using (Max, Pd, SC…)?
i think that may be the answer for our problem :)! using one cursor with multiple curves, whose value then will be mapped into it’s right region 🙂 ! we are using processing (oscP5) for the visuals, and puredata for the audio.
I haven’t splitted incoming osc messages yet in processing, but that wouldn’t be much of a problem I quess 🙂

Splitting and routing messages to select destinations is at the heart of OSC, and largely its raison d’être.
hmm, we used a timeline cursor like in the example « »Xenakis Metastaseis linear », but that delivered us two problems in a processing sketch who was recieving the information:
is it possible to bundle these messages, and send only that one message accros the network? (for better synchronization)
Sorry I don’t have a lot of time this week to answer you.
1. well, in our todo list, this is included because we want to provide TUIO protocol that works with OSC-bundle. However, I don’t think it will be before 2/3 monthes…
2. do you have more information about the « jerky » problem? Screenshots or more explanations?
Hi, I have recently started working with Iannix, and I love it.
I wonder if you could help me with this problem:
is there a way to link the main time counter to the curve/cursor start?
I understand the cursors are relative to the curves.
and curve’s X positioning is just a spatial location (please correct me if I am wrong).
If I could link the general time to cursors, to command them to start walking through the lines/curves, I could in fact use positioning of the lines/curves for 3D sound trajectories mapping in Ambisonics, which would be so exciting and finally the first platform to do it so nicely.
Please let me know if you know a way to do that or
if you have any thoughts or comments
Yes, you can start cursors at a specific timecode using « initial offset » parameter (1st parameter near « CURSORS OFFSET / BEGINS FROM »)
If you specify a negative initial offset, cursor will start at the given time!
