Win7 64bit

[Kearley]

Hi! Any official word on Ableton running on Win7 (64bit)

Since Ableton is my main program, I'll really be anticipating this.

However, I figure things out there have been 64bit for a while now, no?

[Froschfinger]

Working, from my experience. Though, you know, it is not a program compiled in 64 bit. Have not used external instruments and didn't use it heavily ever on Win7, but so far it is stable... anyone else?

[h4nc0]

working great here. all your hardwares need to have 64bit drivers tho.

[Kearley]

Ah, but then running it in 64bit offers no advantage if it was compiled in 32bit, right?

[Froschfinger]

Yes and no. As for Live isolated you will not gain a positive effect from it, since, yes it was compiled in 32 bit. However, your whole system should, when running on a 64 bit Win7, be faster, depending on your hardware. With modern processors etc. you then should see and feel a difference when using a 64 bit OS. I myself have currently switched to 64 bit Win7 for my daytime stuff and see a BIG difference to WinXP 32 bit!

[Kearley]

And Ableton will see all 4gigs RAM?

Wait until you try adding in your 3rd party vsts/aus then you will understand why the majority of Cubase 5, Sonar and Reaper users run the 32 bit app inside their 64 bit o/s, it just works, whereas the 64 bit apps are prone to compatibility issues, plugins not working (alleviated to a degree with bitbridge but not eliminated) and especially those with things such as TC Powercore, SSL Duende and UAD DSP based plugins.

The 32 bit app runs really well inside a 64 bit o/s and gives you more memory than 32 bit o/s (4GB minus the ram used by the o/s).

Live offers 64 bit MIX SUMMING which is cool, but is not the same as being a 64 bit coded program.

Yep working for me too, since the RC was released.
No issued at all. Almost no crashes with live 8. No vst compatibility problem so far. Less latency. Yeah far better than XP 32.
And for day to day stuff, Windows 7 is a pleasure, something I think I never said about any microsoft OS.
I got a powerfull PC though (core I7, 6GB mem) so I don't know how it runs on lower end configs, but with such a config , I have more tracks, VST and effects than my brain can manage (which is not a lot ok but still ;o) )

EDIT : yeah and with some simple sets, I can go down to 64 samples asio buffer ... Most of the sets run bellow 50%, even with a 128 samples audio buffer. If you play music on an actual instrument (as opposed as using samples and loops) this makes a huge difference to have a low latency !

It runs better than XP 32 for sure. Plus I got a chance to clean out my VST folder. Keeping it simple this install'round.

I'm running Ableton Live 6 and I'm having a nightmare in Win7 64bit.

The program suffers short freezes every second or so, increasing depending on the session complexity (it seems).

I'm rewiring Reason 4 but I don't think this problem is related.

Anyone got any ideas? Is this reason enough to upgrade to Live 7 or 8?

Running Win7 64- and 32-bit here without any problems. It works much smoother than Vista on both systems.

ASIO buffer size ?
DPC latency ?

ASIO buffer size ?
DPC latency ?

Running E-Mu E-DSP on ASIO - 48000 Sample Rate
Buffer size 2400 Samples (can't change it) input latency 51.5ms, output 50.3ms (can't change them either)

I tried changing to MME/DirectX with the same result (chuggy).

Dunno what DPC latency means.

Looking at Resource Monitor, nothing seems to be spiking unduly... Ableton's processor monitor's reading a normal 13%... Task manager's reading 3% for ableton while playing minimized... and the same while playing maximised...

Confused!

EDIT :

Turned off Windows Aero stuff, no change.

Renamed the plugins folder, so Ableton couldn't find it, and it's still the same, suggesting that it's not a plug-in problem.

Did more prodding around, disabled the E-Mu E-DSP and re-enabled the on board sound. That didn't help, Ableton was just a chuggy as usual. Tried disabling Delay Compensation, and Ableton outright crashed :

Perhaps I should be putting all this stuff in a bug report somewhere?

EDIT AGAIN:

Just tried the Ableton Live 8 demo and... everything seems smooth. Hmm. So... guess I should upgrade?..

[dinaiz]

Or maybe try and resintall ableton live 7 ? By the way, your ASIO buffer is huge (as is the latency !) . Maybe you can try and install ASIO4ALL, so you can change the buffer size.

I'm on Ableton Live 6 - an upgrade to 8 seems to be the only option on that front...

And I've messed around with the ASIO device control panel and got the delay down to a healthy 5ms

Cheers though! I'm coming to the conclusion that ableton live 6 is just not vista/7 compatible... Will try a reinstall before I do anything else though.
