Whatever the case, I don't think anyone here is in need of a basic midi lesson.


Certainly not!

Can anyone tell me why my MIDI sounds 1/2 step flat? Do I need new MIDI cables?

Seriously, since this thread bubbles to the surface now and again, I hope the Sonar team will take this into account in the next version of Sonar. If possible to improve, the MIDI recording (unquantized) needs to be more accurate. If Live can do it, then so can Sonar.

I think you mean if Live could do it, then so could SONAR.

Hopefully we will all start moving toward Open Sound Control and be done with MIDI once and for all. Midi is ancient tech (what else do we use today that was in use in 1983?). OSC looks promising and its already being adopted by big name electronica performers to trigger everything from midi events (as a controller) to light shows. Much more effective, accurate and robust than MIDI. I wonder if CW is looking at it?

Uhm, to name a few things.
Space Shuttle comes to mind.
Boeing 747s ? wait they're from the 60's.
1970's Satelites in space that are handling internet data.
And cars, even though they were invented in the 1800s.

Admittedly they have had upgrades but they're still in use.

If what is being proposed is adopted, what should we then do with our beloved instruments ? Throw them away ?

Me thinks we have roared ahead going backwards a flying.

A careful reader of this thread should pretty much discern that the problem is with the windoz os, mostly. But if Roland could get it right way back in 1987 with the MC-500 hardware sequencer or ancient Atari could have set a standard then that still has not been surpassed, surely somebody today must be be smart enough to do it again with todays computing power. Or do we just give up hope and stop altogether with the upgrade path routine ?

Regardless of any difficulties in making it work to at least achieve the old benchmarks under the current os, the real and central issue appears to be (imho) that midi has simply been relegated to the back burner and the resources are directed towards including the latest wizbang vitural audio thingamajig or new widget to make the (your choice of user) buy in at the continued expense of the intensive midi users who have, for far to long, been thrown only occasional little tidbits.

Why reinvent the wheel ?

Pianodano, you seemed to change your POV about midway through that post from sincerely supporting old tech, then "relegating it to the back burner". IO think I get what you are saying and to my interpretation, I'll add:

I think the only way a replacement for midi could be workable at all would be one that from the start, not as an afterthought supports midi backwards compatability with some sort of included adapter to be able to "dumb down the signal" for a regular midi device. In this case, as long as compatibility with manufacturer's midi spec isn't a big issue, people with old stuff would continue merrily along and new devices could start taking advantage of new features. The old midi spec could run as a way background process, considering how little is required to run it (in itself, anyway). This would all, of course, need to have major player industry backing to succeed, like from Roland AND Yamaha AND Korg, or whomever.

I still contend that, if the right combination of software and hardware happen to come together on a machine, the actual amount of the jitter that we are really discussing is generally minimal enough for most people - un-noticeable. There are clearly OTHER problems, like the one I used to have on this system running under an M-Audio Omnistudio USB device. My midi and audio were so off from what I knew I played that the feel was noticably sloppy and just "off". I switched to the Layla3g and all is well.

I agree 100% with this statement. RE: backburner. Not exactly. I was attempting to say that the software developers (in our case, Cakewalk) has neglected it as far a correcting the underlying structural issues.

Has ayone here used the "Fit to Improvisation" command in Sonar to line up their Midi and Audio versions of the same track before playing it back?
Clearly you must get it into the track without too many problems first, but to tighten the Midi up to the Audio manually could involve a lot of piano roll editing and time.
Input Quantize the Audio and Midi? Fit to Improvisation?

3) LOL, Dave, my PC's a little more modern than that.




Actually, I believe Dave may have been referring to the power supply. If a computer has lot's of bus powered peripherals and is underpowered, that is it has a power supply that doesn't quite meet the wattage needs of the cpu, mobo, and all internal and external peripherals, then it can cause trouble with midi jitter.

If that's not what he meant then that is what I mean. I have found that pcs that are power starved because of an insufficient power supply can have all sorts of weird problems. I personally wouldn't go under 500W with any modern daw. I have 2 power supplies in my daw. One is a 500w power supply and just powers the mobo, CPUs and onboard usb/firewire chips, which in turn power all usb bus powered devices. I have another 350W power supply that powers all of my HDs, CD/DVD readers/burners and anything else in the chassis.

My DAW is extremely stable and I notice no midi timing issues.

I need a dedicated audio PC. But since I don't have one, I accept full responsibility for the results of trying to do music work on a desktop PC which doubles for music.
