Crackles and dropouts RP 2.0.2 - memory leak?

Here's an odd one... here are the conditions.

In Sonar all software synths respond really well (such as Kontakt, Reaktor etc) with low latency settings, however for this I've tried this with a low and a high ASIO buffer:

The issue is in stand alone but far worse in Sonar Platinum as a VST3.

If I bring up Rapture Pro and the default program, and then glide the mouse up and down the graphical keyboard in RPro reasonably quickly I get a lot of crackles and even drop outs. With other soft synths that have this exact functionality I don't seem to have this at all. Why?


Whilst this isn't something I would generally as a day to day thing, I wonder about day to day operation as far as general performance goes....
 
If anybody else can repro please let me know

Thanks...

You are gliding the mouse up and down the virtual keyboard are you?
 
Hmmm weird what's going on... Looks like a big latency thing, I don't see any CPU issues or issue with output levels, and like I say I see no problem with other soft synths... I don't really have any performance issues...

Too much vigorous mousing may cause more than just crackles and dropouts :P :).
 
Seriously ... thinking it through - the virtual keyboard would have to be 'listening' for input and it would likely queue input it could not immediately process (too the point of overload(?)). It may be able to handle the most dextrous fingers but vigorous mousing may be sending thousands of input requests(?)
 
Perhaps devs can include an ignore 'trap' (I'll call it a mouse trap) when input signal overload is recognized(?)
 
The test could be 'Flight of the Bumblebee' ... on virtual keyboard.

I believe he is referring to your back and forth with Jim Roseberry (Studio Cat) about custom verses off the shelf PC's :)

Sometimes it is best, and if we are to learn from our leaders (Politicians) even recommended :)

I have changed the default program on Rapture Pro, so I can't test that. But I have tried in on a few random programs. I didn't notice anything odd.
 
But one program that I made - Karplangor  (http://forum.cakewalk.com/FindPost/3234851) - can exhibit this.
 
It happens because I have 6 very long samples in the 6 elements and each element has 'infinite' polyphony set.
It could take several seconds for each sample to complete, so it won't take many key hits to get hundreds of samples playing at the same time.
 
When this happens the load increases until a dropout occurs and Sonar's audio freezes.
 
If you resume playback, Rapture Pro continues where it left off and has some more dropouts.
 
If you stop pressing new notes and continue playback again and again until the sample playback finishes, you will be back to normal.
 
I don't see this as a bug, it is by design.
 
If it bothers you change the polyphony settings and make them lower (assuming that is the problem you see).
 
I guess you can also set the dropout time to a few seconds...
