Save patcher state upon saving Live set

Jun 20 2010 | 7:08 pm


I built a little M4L MIDI device and want to add the following behaviour: If I save the Live set then all instances of the M4L device should save their state (number boxes, toggles, etc.) as they would do in plain Max/MSP using [autopattr @autoname 1] and upon opening the Live set the state should be restored. What would be the best/easiest way to achieve this?

All live.* objects are saved and restored automatically with the Live set.
(provided that ‘Parameter Visibility’ is not ‘Hidden’)
Other objects must be connected to [pattr] with ‘Parameter Mode’ enabled.

Just wanted to mention that [pattr] in subpatchers is currently NOT working.
It’s supposed to be fixed with the next update.

Thanks, broc. Using pattr with ‘Parameter Mode’ works as aspected. But it is very tedious to use even with a moderate number of control elements. Isn’t there some way to at least partly automate the process like with autopattr? Or is there perhaps some addition planned in a future update to allow autopattr or something similar to work as expected in M4L? Perhaps there is even a way to write an external that does this? I have no problems with writing some C code.

the reason for using individual pattrs is so that the bound objects can be exposed to the LIVE automation system.

using ‘autopattr’ still works fine – it just does not expose its clients to the live system. you can use autopattr to talk to a pattrstorage and then save a recall state of that with the set. be careful with the clientlist of pattrstorage of course. i know ‘cos i’ve done it, using the andrew pask (panukul) method posted here:

personally though i find it usually much more worth the effort to use lots of pattrs – the above method was just a specific circumstance of mine. (bring on max 5.1.5 !)
