Model:Samples does not let you configure midi clock and start/stop individually, like you can on the bigger Elektrons. It either sends clock and start/stop or none.
Not sure if TR6s or the Microfreak can do that.
Filtering out start/stop entirely (with a midi processor) wouldn’t help I guess?
You need a midi processor (like the Midi Solution Event Processor, Bome Box etc.) or a midi interface with filtering capabilities like the Blokas Midihub.
When you filter start stop, you´d have to start and stop the TR6s and Mirofreak manually. You could test with a computer befor buying a midi processor, the free Bome Midi Translater software should do. For that test, all midi messages would have to go through the computer.
The Midi Solution devices draw current from the midi connection, which is actually against the midi standard, but apparently it works for many configurations and of course means you don´t need another PSU.
Also Octatrack, Analog Four/Keys, Analog Rytm, Digitone and Monomachine and Machinedrum all have seperate settings for sending/receiving clock and sending/receiving start/stop messages.
Apparently Digitone can do that as well! It came with a firmware update, I just checked the release notes. Now that’s nice!
I had older versions of the pdf manuals and there was only a sync on/off setting which combined clock and transport. The newest manual lists seperate settings.
