The Great MIDI riddle

Help a noobie out :blush:

i have the octatrack mk2.
i have an analog four mk2.
i have a polysynth with keyboard, has midi in, out and through ports.
i have an analog rytm mk2.
i have a monosynth with keyboard, has midi in and out.

i want the octatrack to act as a midi clock and transport control source to all maschines.
it has to sequence and send midi clock to polysynth, as well as receive midi from polysynth to use in octatrack’s sequencer.
the polysynth has to pass notes through to the analog four to play its voices.
the analog rytm has to get the midi clock and transport control from octatrack.
the monosynth has to get midi, transport and clock from the octatrack.

is there a solution to this crazy riddle? it is driving me nuts and i might soon eat the manuals. any solutions welcome, like midi devices that would make that all possible without computer. i have an ipad but would prefer not to use it if possible.

level hard: can the monosynth also send notes to octatrack for sequencing purposes?

MUCHAS GRACIAS!

Do(es) the synth(s) you want to use to send information to the OT have an option to “turn local control off”?

Do you own a midi thru box? Such as https://www.tindie.com/products/hotchk155/banana-split-6-way-midi-splitterthru-box/

Are you comfortable with the midi channel structure?

Thanks for answering!

Yes, both mono and poly have the local off mode.

No, i don’t have a midi splitter but can as well get one.

I am quite okay with the local midi structure. Is there an option to store all those settings in octatrack and analog four so that i do not have to config it for every track i make?

A quick try in between meetings at work…

i want the octatrack to act as a midi clock and transport control source to all maschines.
That’s easy - just go into the midi settings of the OT, select sync and tick the boxes for sending clock and song position (don’t remember exact terms, not in studio right now)

it has to sequence and send midi clock to polysynth, as well as receive midi from polysynth to use in octatrack’s sequencer.
Yes, first you just connect midi out from polysynth to midi in of OT. Then you connect midi out from OT to midi in of polysynth - as mentioned earlier, you would benefit from a midi thru box which would allow you to ignore chaining your connected polysynth, AR, A4 and monosynth and instead each device would have their own input from the thru box.

the polysynth has to pass notes through to the analog four to play its voices.
Sure, just set the OT in midi mode, select a track and set its midi channel nr. Then just set the same midi channel nr for the track you want to play from the A4. Connect midi thru from polysynth to midi in of A4. Turn your polysynth into local mode and select the midi track you want to use in the OT. Now you should be able to play and sequence the A4 from the OT, receving note input from your polysynth. Stretch goal would be to set auto channel on the OT to the same midi channel that you send from your polysynth - in an ideal world that would let the selected midi track in the OT to be active, allowing you to switch channels and sounds based on that instead of changing the midi channel you use to send the note input from the polysynth.

the analog rytm has to get the midi clock and transport control from octatrack.
No problem, just set the midi sync setting to receive midi clock and song position in the AR settings. Then you simply connect midi thru from A4 to midi in of AR.

the monosynth has to get midi, transport and clock from the octatrack.
Simply do the same as above, select the midi channel to be the same on the OT midi track and the monosynth. Make sure that your monosynth is set to receive midi clock and then connect midi thru from AR to the monosynth.

is there a solution to this crazy riddle?
I think so. You would very much benefit from using a midi thru box or something like a midi center (I use MOTU midi timepiece AV with 8 in/out that let’s me route in a very flexible way).

Previous posters have provided some excellent advice. Note that you can achieve this without any additional MIDI routing boxes:

OT2 Out to AR2 In
AR2 Thru to AF2 In
AF2 Thru to Poly In
Poly Thru to Mono In
Poly Out to OT2 In

You are going to have to set MIDI channels and MIDI settings on all the instruments very carefully.

If you add this requirement, you are going to have to add a switch or merge box at the OT2‘s In port (or just switch the cables manually).

^^^ That ^^^ Nailed it @PeterHanes!

The OT stores its MIDI configuration settings in a Project, and the individual MIDI sequencer track details in a Part.

The AF stores its MIDI configuration settings in a Global slot, of which there are four available per Project.

The AR system is the same as for the AF.
