Title: problem with Minilab and MMC Play/Stop messages
Post by: csurieux on April 24, 2020, 06:08:01 pm: Hello,

I just discovered that Minilab sends a SYSEX message (just as an AKAI) for the MMC Play (and stop) messages.
Is there a way to have it sending directly the MMC value which is FA (FC) ?

Thanks for help.

I don't have a Minilab MKII. But as far as i can see in Midi COntrol Center, then Minilab MKII's pads can be set to send MMC. There is a list of transportbar messages to choose from - including play and stop.

What do you mean by "FA (FC)"?

The general form of an MMC message
The general form of an MMC message (that is sent to, or generated by, an MMC device) is:

0xF0 0x7F <deviceID> 0x06 <command> 0xF7

0xFA was simply the translation for 11111010 in hex (MMC Play), from https://www.midi.org/specifications-old/item/table-1-summary-of-midi-message
So it appears that Minilab is Ok.

Back again on this, after many loops in discovering what kind of midi info I need to send.
The SYSEX play message was a bad option, my device understand midi sync transport messages, with the START AND STOP commands.
Start being really a simple 0xFA sent, but I have no options to send it from MiniLab MkII.
Could send of MMC commands be be implemented with STRT and its STOP counterpart ?

As i does'nt have a Minilab, then i can't tell, if there is a file somewhere, where you can change the messages.

Perhaps your issue is about the recieving unit?

The Start and Stop in the MCC are messages, I need to send commands.
A MMC message is a SYSEX but a MMC real time command is just one Byte (Start is OxFA without any special formatting).
Minilab is sending messages, not commands.
