Vegas 4 and Midi clock help please?

I have a client with a Korg Triton. We usually have Vegas generate MIDI clock so that we can make multiple passes with the keys. Last time he was here, I think I was using Vegas 3. This time, using Vegas 4, it didnt seem to want to work right. I confirmed that the cable was sending midi clock activity ( though I didnt have a number readout).

As soon as you turn the "generate midi clock" switch on in vegas, the keys would start playing. On the time display, I chose " midi clock out" and the numbers sat at zero till you hit play which seemed fine, but the keys acted like you hit play, just from turning on the clock generator.

What can be going wrong? In vegas 3 after you hit the generate switch, you would need to hit play before the keys would start going, and when you hit stop, even with the generate switch still on, it would stop.

I've tried to get midi clock to work correctly with 4.0: in vain. It got better with 4.0b, but still results in a painfully slow lock and gaps in sync you could drive a truck through. Midi clock was never all that wonderfully tight anyway, but it was fairly functionable until it quit working in 4.0. However, if you happen to be a using a rewire application and SF implements rewire in Vegas as they just have in acid, the problem is solved with dead accurate sync, though that won't help with the Triton.

thanks. Am I correct in believing that midi clock shouldnt start generating till you hit play ?

Yes, of course the keyboard has to be set (usually in Global or MIDI mode) to "External clock or Slave" then with Vegas set to "MIDI clock out" once you click Play or Record in Vegas the keyboard should start. Some devices require you to press Play and will wait until it receives the Master's clock data.

right thats how I did it before. But now ( vegas 4.0c ) clock begins being sent as soon as I click the generate clock button, even when the transport is stopped

Generating clock msg is the correct thing to do once you set it active. Sending MIDI clock while not actually playing is actually specified in the MIDI spec. It permits the slave to "Lock" to the tempo of the master before a start msg is sent.

A slave device should not do anything until it recieves a start msg.

I have tested this against a number of MIDI clock slaves, and all behave correctly with Vegas. I don't have a Triton to test with, so I can't say what is going on.

I will look deeper.

What are your advanced page settings for MIDI clock in Vegas?

I reset to defaults, as thats how I had it last time. Now maybe something else is weird

This guy brought the same TYPE of triton kb as last time, but turns out it is a different unit than last time. I reconfirmed that it works in vegas 3 even with that keyboard but not in vegas 4

I set my MIDI clock out in advanced to " On start and stop of playback and record" but tried other combinations too
