enabling dsp (with adstatus switch) only works when max is active application?

April 17, 2007 | 3:11 pm

Hi,

Could it be true that enabling dsp by sending a 1 to [adstatus switch] only works when max is the active (as in focused) application?

I’m sending an event from logic to max that triggers a 0 and 1 second later a 1 to [adstatus switch]. On 0, dsp switches off, but on 1, dsp only switches back on if max is active.

Could anyone confirm this?

Thanks,
Mattijs

Here is a patch to reproduce.

Description: see previous post.

Expected results: dsp can be turned on and off regardless of whether or not max is the active application.

Steps to reproduce are in the patch.

Max 4.6.2. Mac OS 10.4.8.

Is this intended? If so, is there a way to circumvent this?

Greets,
Mattijs

mmm…. not completely true. I can turn off dsp when Max is not the active application as described in my previous post, but the opposite is not true.

Ex.:
Setting toggle on then cmd-tab to another app.; the second toggle is set to on, but dsp is not turned on. Don’t know if this situation is a problem for you, but there’s a problem, for sure.

Best,
Julien.

Thanks for confirming, Julien. This is definitly a problem for me. I need to be able to turn dsp on and off while max is not the active program. Off will work, but on won’t.

Summarizing, two confirmed problems:

1) graphics of the ezdac~ object don’t update at all when max is not the active program

2) switching dsp on doesn’t work when max is not the active program

I would greatly appreciate if someone from cycling 74 could confirm this.

Thanks,
Mattijs

With [adc~] and [dac~] audio does turn off, but not on.

With [ezdac~] happens the same, but the state doesn’t change.

–edit: should have pressed ‘post’ earlier….

Mac only, audio does not turn on when MaxMSP does not have focus.

Also, ezdac~ is not updating correctly.

I can’t think of a sensible workaround Matthis – rewrite your patch? Get a PC?

:)

We’ll have a look at it but don’t hold your breath.

Thanks Andrew,

Is it possible for you to let us know when you had a look? It’s important for us to be certain whether or not this will be fixed. If this proves permanent I’ll have to rewrite a significant part of the progam we’ve been working on this last month. Please let us know your findings..

Looks like it has been fixed in 4.6.3!

The bug exists in 5.19. Audio turns off but not on with adc~ object
