I'm trying to figure out how to switch from SetList to Combi to Program (etc) using sysex.

I'm using MaxMSP and I captured the sysex that was generated by the Kronos when I pushed the Combi button.

I then switched the Kronos back to SetList mode and tried to send the previously captured sysex back to the Kronos to get it to go into Combi mode but nothing happens.

I'm certain that the sysex message was sent as I inserted an iPad into the MIDI stream to monitor the data.

Is there something else I need to do to make this work? As far as I can tell, everything is enabled on the Kronos to allow sysex to work.

Thanks,
D

Sorry, I can't help with your problem. But I'm curious, what's your application for this?

It's not necessary (or let's say: highly unlikely) that the message the Kronos sends when going into combi mode is the same as the message which MAKES the Kronos change to combi... It's like the difference between the sentences "I'm in combi now" vs. "Please got to combi".

I would not expect the Kronos to react to the message you captured. Otherwise, if you were lucky to have two of them linked together via Midi, the "slave" would always do exactly the same as the "master" at every single touch of knobs or display - not very practical.

The accesory DVD #2 contains some documentation about midi and sysex implementation, maybe you find something there!?

Do you know this to be the case or is this just speculation? I don't agree with your arguments for why it must be as you describe. First of all, the only reason to confirm that "I'm in combi mode" is if a request is sent and in such a case I can't imagine why it would be necessary to send a huge sysex message just to ACK. Further, if what you say is right, then I would expect two messages, one with the request and the other with the response. Wouldn't you want an external editor (if not a slave Kronos) to know that the request had been made? Finally, if one is indeed lucky enough to have two devices connected together, then one would typically configure them with different sysex IDs specifically to prevent the issue you describe.

To change the mode from your DAW, insert one of these sysex parameters:
For SetList: F0 42 30 68 4E 09 F7
For Combi mode: F0 42 30 68 4E 00 F7
For Program mode: F0 42 30 68 4E 02 F7
For Sequence mode: F0 42 30 68 4E 04 F7
For Sampling mode: F0 42 30 68 4E 06 F7
Note: these are zeros, not the letter O

I have built a replacment for Apple MainStage using Max/MSP to control my rigs. When I switch to a new song, sending a program change isn't sufficient if the Kronos was switched into another mode manually and/or it is in editing mode. So I am hoping to be able to simulate pushing the Exit button followed by an explicit switch to the desired mode before I send a program change out.

That way I can guarantee that no matter what was happening before, When I load a new song in Max, the Kronos is guaranteed to get configured properly.

I went back and took a closer look at the sysex that I was capturing and sure enough, the very first sysex message is identical to these examples below.

So I took another look at my hardware environment. Turns out I was monitoring the wrong place and even though the messages were being sent out of my Mac, my MOTU Timepiece was blocking (muting in MOTU terminology) outgoing sysex messages.
Once I unmuted it, I was able to make this work.

Thank you, fclef, for providing those examples --- that caused me to be able to look in the right place.

Really appreciated.

I know a request is different from a response but I would have been astonished if the request itself didn't get sent out and it turns out that it does.

To answer a question raised in one of the above posts, the instrument and manufacturer are specified in the SysEx string. In this example F0 42 30 68 4E 09 F7, (the string to place the Kronos in SetList mode) the second pair of numbers (42) identifies the maker as Korg, the fourth pair identifies the specific instrument - in this case a Kronos. If the fourth pair of numbers was 50 instread of 68, the SysEx data would be looking for a Triton. These codes are always identified in the instrument's MIDI Implementation Chart.

Yes but most synths that I've ever seen have a device ID that you can change, so that you can distinguish multiple identical synths in your environment.
That may be less of an issue these days if one uses a multi-port MIDI interface so there's never more than one device on a midi cable.

Well, I spoke too soon --- these sysex messages do work to switch you from one mode to another, but they don't work if you are in a place where you need to press EXIT one or more times to get back to the base mode.
The EXIT button does not generate a sysex message so unless there's an undocumented mechanism, there would seem to be no way to guarantee that you can get back to a specific mode.

Hello,

I have been learning a little bit about FM, speciality on Kronos (Mod-7)...so, on prog mode, would be possible to receive a "real time" Sysex message (not load sys file!!!) for live performance using a equipment like this?

Thanks

Your equipment is going to send DX7 specific SysX messages that the Kronos won't respond to in real time. However, you can certainly send Kronos specific program and parameter edit messages to the instrument in real time and it will respond. All of the parameters can be edited in real time. You can work through Korg's SysEx docs or you can simply open the MIDI monitor in the editor and it will show the SysEx messages being sent to the instrument. You can use these with any hardware or software capable of sending the messages.
