Horrible overload issue with MusicLab RealStrat VI

[csansom]

I sent this in an email to MusicLab, but in case it's a DP issue I'll repeat it here (edited to remove the obvious DP info):

=====

I’m suddenly having terrible trouble with RSE [RealStrat Elite] in DP 11. I’ve opened a project I completed recently, just to check something out, and it’s doing something it’s never done before. And I’m sure I successfully completed this project /after/ I upgraded all the Real instruments.

In DP’s Audio Performance window, the ‘Real time’ bar is completely full with red. It’s usually maybe a quarter to a third full with green, and I rarely see any red at all.

In the Effect Performance window the two instances of RSE I have running (lead and rhythm) are top of the list, with Lead's bar full and Rhythm’s about 80% full. (Rhythm is RealLPC, but the behaviour’s the same.)

There’s a nasty crackling overlaid on the audio from all the VIs (not just RSE) when I play it back, and the tempo’s noticeably slower than it should be.

The signal is getting from DP to the plug-in, similarly from the music keyboard: RSE’s dummy keyboard is responding as it should.

Earlier on I did tinker with the sample rate for the project, mistakenly changing it from 48k to 44.1k, then changed it back again when I realised my error, but it doesn’t seem to have affected what RSE’s doing.

What on earth is going on? I expect it’s something terribly obvious that I’ve missed - something to do with output? Some serious incompatibility seems to have arisen somehow.

You might try Saving a Preset for the problem plugins, removing and re-instatiating the plugins, then restoring the Presets.

Another possible fix: Load the entire project into a new, blank project file using DP's Load command in the File Menu.

Sorry - been detained by other matters for the last 24 hours or thereabouts.

I've tried all the things you suggested, HCMarkus (I'd already tried most of it before your post), but to no avail. All as horrible as before, so for now, to get the basics of this piece done I'm using a couple of cheesyish sounds from Kontakt's default library.

I have, however, had a reply from MusicLab, who asked me to Sample DP in Activity Monitor and send them the result. We shall see.

At the risk of covering the obvious, you do reboot before a session, yes? If not, do so and see if anything changes.

Well thanks Mike, and I have to confess that I don't often reboot before a session. But then I don't really have 'sessions' per se, it being a one-man MIDI operation. More of a question of going to my studio to tinker for a bit until it all comes together in the end.

However, now I have and sadly it's just the same. So I wait for MusicLab to get back to me having examined the sample I sent.

Ok, good to know.

Memory leaks are ever present and the 'whack-a-mole' of every developer — which is why one must reboot now and then. If, however, rebooting didn't change anything, that rules it out as being the cause of this particular behavior.

One trick in my diagnostic arsenal is the following Terminal Command,

sudo purge <return key> followed by your Admin password.

It frees up any cached RAM. Not as good as a reboot which also clears RAM held by your apps but, if it changes anything, again, you know that you're dealing with a memory issue.

Thanks Mike, but given that parting shot I had no expectations when I tried the purge command. And my expectations were met in full - no difference, in other words.
