MIDI Program Change bug - still not fixed

I reported this last year, and I'll report it again since I see it has not been fixed.

When firing a PC message from a MIDI clip, if the next clip fires the same PC message, the second message is not sent.

For example:

scene 1 = PC 25
scene 2 = PC 25

PC 25 is only fired on the first scene, not the second.

This is a major problem if you have a device that toggles functions on and off with the same PC message (i.e. start and stop).

I'm getting around it by firing MIDI notes and translating them to PC messages in Midipipe.

Hi,

some synthesizers "glitch" when receiving Program Change to change their sound bank. Live recognizes the equal Program Change setting of two clips and therefore does not send out the second clips Program Change to avoid any sound glitches in the synthesizer.

Best,
Daniel

so I guess you're saying the bug I'm reporting would be a *feature*?

OK, so do you have any suggestions as to HOW I can send the same program change messages in sequence to deal with devices that toggle functions?

Thank you

Well, just make duplicate programs with different numbers on your device ie. 25 and 26.

But how do you send program cahnge messages?

?

but the point is that the eternal device I'm sending PC messages to has a fixed, unchangeable midi map. Each feature of the device can be accessed via a specific PC number.

For example, to mute it you have to send PC #25. To unmute it you send PC #25 again. Or, to record you send PC #4 and to stop recording you send PC #4 again.

To send a PC message to an external device in Live, one has to assign a PC number to a midi clip. That PC message is fired at the beginning of the clip. If you put 2 clips, one after another, with the same PC message, only the first clip will send the message.

The only way around it now is to put midi note messages in a clip and use another application to convert the notes to PC messages!

So in my book, Live not sending the second PC message would be BUG.
