Here's an updated screenshot:

After doing some updates ,optimizations and tweaks to Puppy Studio Pre-Alpha,here's the result:

JACK is now running stable without Xruns at 0.4 ms (20 frames x2 buffers @ 32bit/96kHz ,realtime) - without an RT kernel Smile


Sounds very promising Smile Cant wait to preview it ! Smile

Synth

As a guitarist with some usb recording gear I have a bazillion questions, I am by no means an expert in guitar or recording!

LINUX

    As I understand you intend to use RT kernel... yeah?
    Are the results in your screenies on a stock 412 with stock kernel?
    I assume wine is necessary for ASIO driver... yeah?
    What distro will you base your woof Studio Puppy on? (a, d, s, u)
    When can you upload something for testing?
    What wine version?
    Doesn't Linux have an alternative to ASIO? (If not it should!)



RECORDING

    Will latency improve much with RT kernel? (assuming you are using stock now, and 2ms is negligble anyway.)
    I have a Zoom effects device (works fine in doze) for my guitar, do reckon it will be supported?
    I have a Behringer usb sound device which I hook my mixer up to, same?
    Midi? (not that I use it much, drum samples maybe)
    Drum machine app?
    I have not used JACK, does it support playthru recording, like Audacity?
    Audacity is handy for quick edits, is it part of the package?


That will do for now.

Very keen! Mr. Green

Cheers.... Mick

Hello there!

I am new here and I as MIDI based musician am very interested in the "Puppy Studio" but I am a bit confused by what you wrote synth and have a couple of questions:

synth wrote:

RT mode in JACK is useless without a Realtime kernel. It's extremely unstable. You're forced to use the non-RT mode which can give you 4~5ms latency in the best case with a monster PC Sad

Windows XP performs much better than Puppy with a standard kernel. You can get latencies down to 1~2ms with ASIO output and an optimized XP.

With a RT kernel,you can finally use the RT mode without fear that your app will disconnect or crash.The results are amazing:
Much better than XP Smile


Is now XP performing better than the turbopup with standard kernel?
Is RT mode in JACK really useless without RT-Kernel? A few posts later I understand:
synth wrote:

But I found a nice workaround - setting the timeout in JACK from 500ms to 8000ms solves the problem Smile
Now you can use the RT mode but you'll get Xruns from time to time because of the lousy 2D performance of WINE.

synth wrote:

That sounds good to me Smile

Will the turbopup stuff be included in Puppy Audio?

Since I am a beginner with Puppy, I would like to know how difficult it would be to make a RT-Kernel based version of Puppy Audio or turbopup and if a RT-Kernel is really needed for getting say 5ms latency for JACK with MIDI triggering a VSTi through wine-asio.

As a start in "Puppy-doing" I plan on doing a Puplet which is turbopup based with:
-latest Firewire : FFADO and FreeBob (latest from svn)
-WINE-ASIO
-FST (latest from git)
-jackdmp (latest from svn)
-VSTi-Plugins (like Pianoteq piano)

Thank you synth for the great things you do for audio on Linux!

Regards,

JazzyPuppy

Puppy Studio is not a puplet based on Puppy 4.2

It's a next generation (woof-based) Puppy with the latest kernel and the optimizations of Turbopup.

It will include the latest (stable) versions of everything needed for pro audio work Smile

Hello synth!

Thanks for explaining me this stuff!

I'd be more than willing to be an alpha tester for Puppy Studio.

Regards,

JazzyPuppy

Hey Synth,

Its long been a dream of mine to get a RAM studio!
At the moment i have tried to do this with Slax, and LiveScripts,
both cool "functions"of linux, but Im not technical enough yet to go insert my
owen real time live kernels..

So i've googled the earth over many times, and this seems to be the
only RAM studio solution!!! Very Happy

So Im available quite a bit to do alpha testing, bug reports, I have a
desktop and a Laptop (single and dual core) can do some comparitive tests for you?

Only if your intrested in help at this time of course!
Cheers, and if there's anything you can think of that
could do with some upgrading (artwork, log in sounds, etc)
i offer my help.
-Harry
