waveform cursor and mouse question.

Jul 23 2011 | 11:03 am


Can anyone tell me how to drive the waveform objects "cursor" from the transport object? I can find no specific references or examples of the two being connected, or any connection methods outlined in the help, sorry but if it’s not spelt out for me I just won’t get it lol.

Secondly, I was wondering if it’s possible at all to convert the waveform zoom features from a mouse toggle wheel?

erm.. here’s the roughing out patch, it at least has most of the work done if anyone would have a look a it for me I’d be grateful.

Hi coda
I looked at your patch, and you seem to have the usual [waveform~] GUI stuff sorted. Before I respond, can you clarify why you need to use [transport]; I guess to sync to other time/beat-critical stuff, but in your example, [transport] isn’t really doing anything. If you’re asking for a simple GUI representation of loop-selection for user-control then you seem to have that sussed, if it’s for something more complex then let me/us know and we’ll try to help. As for the scroll-wheel question, I think I’ve seen this come up before, so search here for "scroll wheel", "mouse scroll" etc. All I can tell you in this respect is to look at stuff you prob already know, i.e. [hi] and [mousestate] helpfiles and ‘see also’. Sorry not to know more…

ahh, noob your granular patches are pretty insane man, indeed I’m attempting to patch together a granular type tool, well an editor and basic sequencer for video that can also be granular using stretching and loops to build up rhythms etc..

It wont run like a step sequencer though (I’m hoping) more like a self playing timeline, with loops being sequenced using "go to" type timeline markers and slip editing features too, that would allow (once a sequence is composed) the video to be slipped out to different frames without having to disturb the patterns.

The ‘go to" markers will indicate where on the timeline to loop and the amount of times to loop before continuing to the next marker. It will need to handle 3 or 4 gig sized video files at around 720p 35 fps at times, has to be stable and all that what-not.

Thanks for your help DEvo, I’ll have a shot at it and get back.

Hey DEvo that’s cool of you, thanks this is plenty for me to be getting on with, :) You guys are top notch.
