Topic: New iteration of version 3.05 gives me much better performance

"btw we have updated v3.0.5 today in order to fix a small performance regression, so if you are using the "old" v3.0.5 you should also notice a small improvement."

Julien,

I don't know what changes were made, but this new revision that you released yesterday (7\28\09) gives me a very noticeable improvement in performance. With the previous iteration, my system sometimes locked up when polyphony was high. With this new iteration of 7/28 I'm only very rarely going above 48% demand on the cpu when playing series of big, sustained chords and never locking up. Huge difference. Thanks so much.

Yes it took us some time to find out the problem despite a few reports of performance issues. We have been shuffling a lot of code for v305 and the mistake was hidden into a huge pile of harmless and boring changes. Sorry for that. But I'm glad that everything is back to normal.

Re: New iteration of version 3.05 gives me much better performance

I had noticed about a 7-10% increase in reported usage on the piano models (especially the C3s), and they ramped up more steeply with higher polyphony -- glad to see things are "back to the future!"

(I was feeling suspiciously like I was in 2.3 land again.  ;^)

Re: New iteration of version 3.05 gives me much better performance

My original post mistakenly overstated the cpu load used by the new iteration. I've corrected it now--I'm rarely getting more than a 49% hit on the cpu running at 44100, and that's only when trying to cause problems by banging chords.

I'm looking forward to hearing about how the revision affects the netbook and Linux netbook situation.

Today I updated from 3.0.4 to 3.0.5 (released on 28/7/09) Linux 32bit, platform eeepc 901 netbook. I played with Grand C3 Solo (most demanding) a little and feel no difference. I had no issues with 3.0.4, so I don't know, if 3.0.5 becomes better (or worse, or equal) with 3.0.5. Alas I don't remember, how high the load percentage was with 3.0.4.

I use 44,1 kHz, 64 samples, performance index 6 (whatever this index means). I have reverbation in my small Yamaha mixer, so I win performance by switching it off in Pianoteq.

Re: New iteration of version 3.05 gives me much better performance

It is possible that I can hit only 29% playing the demo Chopin Waltz running at 192KHz??  I must be doing something wrong.

AFAIK 192khz is very taxing on your system. I once tried running 96khz on a demo song and it hit 60%!

I'm just back from a few days off, and am testing the latest 3.05 right now, but the first thing I notice is that this version has the same "bug" on my computer - the main screen is a hog - whenever I click on the Options screen, the main screen remains "on top" of the Options screen.

You had made a small change to version 3.04 for me which solved the problem, and now I need the same assistance for 3.05.

I usually use Pianoteq in conjunction with Goldwave (wave editor) and using Alt/Tab, to go from Pianoteq to Goldwave, always leaves the Pianoteq screen over top of the Goldwave screen.  The only way I can hide the PT screen is by minimizing PT.

Just for reference:  with my current standalone configuration, I'm running the Chopin Waltz, Op.70-1, and getting 16-20% usage at 96kHz and 128 samples, with the internal sample rate at 48kHz.  (Performance index = 25, polyphony = 256)

I have the exact problem... Not a huge one, mind you. But sure can be annoying.

Re: New iteration of version 3.05 gives me much better performance

Oh, and while we are at it, here's another problem:

After you play a midi file in the standalone, the player (the timer) just keeps going, even when the song is over. I am not sure if this could be a problem (memory leak?), but can't it stop automatically, or is it some kind of feature that is ill-presented?

Re: New iteration of version 3.05 gives me much better performance

True, during playing it should stop upon the end of the file (the timer, that is).

During recording, the user is the only one who should be able to stop it. How about a quick fix of that for 3.06?

Hard work and guts!

Yes the problem was that I could not figure how to reproduce that issue. It happens when you go into a sub-menu of the standalone , for example "file/recent midi files"

We have updated the v305 for windows, the bug should be gone (latest windows version should display : v3.0.5/20090805)

Regarding the midi file player will we fix that later -- however it is not at all a problem that it keeps going, no leak or whatever.

The bug is gone - thank you - may it stay dead.
