Hi there, new organelle lover here 
I’m just wondering how do I have to set up a pretty basic thing. I’m conecting my midi out from my interface to the midi in trs of the organelle. It works fine when I play midi notes on the keyboard but I would like the organelle to start its own sequencer when i hit play on logic. Anyone could help me with it?
Peace
Is Logic sending transport control messages to the Organelle?
Don’ know 
I found that video. Will have a look at those settings https://youtu.be/OqpP9p0pwgQ?si=yazbt9fR1td8iCws
I sort it out to send clock via logic to the organelle Now the issue is that some patches do accept clock messages and some don’t. Is that normal? Is it easy to tweak those patches in Pure Data to enable external midiclock on them?
Thanx
Yes, it is normal. It’s up to a patch if it uses MIDI clock. For example, a basic synthesizer patch might not be programmed to use MIDI clock, but if you added an arpeggio function to that same synthesizer patch, it might be helpful to use external MIDI clock to control the tempo of the arpeggiation.
The [midirealtimein] object handles MIDI clock in. It is easy to add this single object, but what you want to use the clock for (e.g. arp tempo, etc.) is the interesting part and may require learning the nuances of PD. There are many threads in this forum about programming tutorials and resources.
