Great question @wrlmuzik, it inspired me to dive a bit deeper into my own MIDI setup (thank you)! I wanted to be absolutely SOLID on my end before sharing, so here we go!!! You’re exactly correct in your opening comment…in my own setup, ProTools sends midi out via MicroExpress, to SyncGen 3LX’s single input/MergeRX. The clock from ProTools is ignored by 3LX, which merges the incoming midi data with its own clock. So to integrate the 3LX into my own setup, I had to ‘disrupt' all the midi in cables, so they feed from 3LX (instead of directly from MicroExpress). Then I simply route all 16 midi channels from a single Micro Express midi out to 3LX’s MergeRX, which streams out via Multi-Split to all my connected synths. I then choose a ‘global channel’ for each synth to receive, which gives me complete routing options from ProTools via midi channels. It’s a bit more complicated than a straight connection to and from our midi interface, but once we’ve mapped everything, and labeled it, we can save as a template 🤟🏻💥. The 3LX has easily accessible internal dip switches for all it's outputs, allowing us to choose whether or not the incoming midi data is merged, or ignored (handy when feeding clock to outboard gear, live, etc.). Just for clarification, any incoming midi clock is always ignored (filtered) by 3LX’s MergeRX 😆🙏 I hope this helps @wrlmuzik, PLEASE reply back cause I wanna know my friend!!! ☺️. Thanks for sharing, and for the inspiration! Have a great week! -hw

@@hiwattmarshall Thank you so much for that explanation. I just received the 3LX and the Multi Split will arrive in a few days, so I'm very excited. I'm using a CME U6 Midi Pro midi interface, which has the same options as the Micro Express in terms of routing and filtering Midi, so I think it's just Midi Out of my NI S61 (master keyboard) to Midi In on port 1 of the CME, and Midi Out of port one to Midi Merge RX on the 3LX. I'm using a few synths and eurorack - 1- Midi to CV module and 2-clocking Pam's New Workout (via mmMidi module). So I'm thinking I won't need to change any internal dip switches, except maybe the output to Pam's where I just want it to send clock and not notes? Anyway thanks again-it was your video that inspired me to dive into this! I'm just waiting for my ilok license and then I can start getting it all set up.

Yo Ken / All - sorry for late reply - buried in firmware and software as usual and not sleeping much !!!!! Ken’s reply is absolutely spot on - obviously using 3LX to generate the precision outgoing MIDI Clock means transmitting DAW / Software generated MIDI Clock is not needed by our hardware so it is permanently ignored at the Merge input. Merging two MIDI Clock streams (aside from getting the jitters!!!) results in outputting double tempo which isn’t usually the aim so we felt best to block incoming sync totally just in case end users forget to disable transmission at the DAW end - but - it’s a good idea to disable anyway if you can and leave the outgoing DAW MIDI Port feeding 3LX Merge In clear for events / control messages - with MIDI being serial - less is always best. If you don’t need it - don’t send it down the cable etc :)))) more coffee required - best and much love and respect to All - D

Hi Ken, FINALLY getting to the point of cabling up all my gear and starting to look into setting up the 3LX and multisplit. I've been trying to do some deep dive research on all of this stuff. I have (4) old MOTU MTPav units that can utilize clockworks (like your microexpress). If I sent the out of the MTPav to the MergeRX, can I in theory send one of the streams back into a midi IN on the MOTU (that should be carrying the 3lx clock signal)? Then that clock signal should transmit to every midi port on the motu, but I would just need to disable the protools sync from the daw so it doesn't double-clock? If that does work, that could mean in theory that there would be more than 16 "global channels" to use and most of the gear would be attached to the motus and not the 3lx/multisplit? Im assuming when you said "global channel" that means you have 16 total channels to spread across all of your gear, so if you wanted more than 16 different channels/synths playing at once it would hit the limit? Lastly if you have all of your synths/fx's connected from the multi split to midi-ins on the gear, would you connect the midi outs from that gear to the micro express then (even if it was for sysex patch dumps)?

I just ordered the midronome yesterday, and this video popped up this morning. 😅

Great question R, thanks for sharing here my friend 🤟🏻🙏🏻 My MOTU MicroExpress came with Clockworks software, which allows me to internally patch my midi inputs/outputs. The tricky part is 3LX has just one input/merge. So, if you have no means of internally routing your midi connections within your computer, you may have to sort of 'break' your typical setup. In my own studio, I like to use two controllers...my Virus KC, and my Arturia. They're both patched directly into my MicroExpress, then I take a single output from the MicroExpress, back to the Merge In on 3LX. I then use Clockworks to choose which controller is in play, by internally cross-patching in the MicroExpress. 3LX then distributes its own clock to all my connected gear (effects included). I didn't realize how important my MicroExpress was gonna be in my setup, apparently there are only a few MOTU midi interface's that came with Clockworks...that was lucky!!! I hope this helps R, and for sure don't hesitate to reach out to David at Innerclock Systems...the guy is a scientist hahah!!! Please continue this thread, it's a great place to share nerdy stuff like this...and I'm curious how you integrate it into your studio! 🤟🏻 Thanks again R, stay safe 🙏🏻 -hw
