    Thank You @ddw_music and @whale-av. I still haven't tried these solutions out, but now I have a few to try. I will start with the midi pipe method and then these others.

    Thanks, I will post how this works out or which method is easiest to implement.

    Well I have a bunch of Midi controllers and it happens whenever I plug in more than one. I have two other ones on Channel 3 and 4 and If I plug them both in I have a similar problem with the wrong channel coming up for one of them. But like I said, i don't have this problem in Max or any other software, it's a unique problem with Pd.

    @jameslo Yes it's kind of weird to have one device with 2 midi channels.

    It has two teensy microcontrollers in it, each one is a different midi channel.. I could have made it with one teensy if i know what I do now, but at the time that seemed easier. They both have a usb cable that goes into a usb hub in the midi controller, and I have one usb cable coming out.

    i'm making another one now and it will just be with one teensy

    Here's a demo video.

    @whale-av OK thanks I'll try the midi pipe!

    @jameslo they come up as two seperate devices

    HI and thanks for the info. That makes sense about the 1-16, 17-36 thing, because the other midi controller always ends up to be channel 17, 18 or 19.

    i don't think it's a Mac OS problem, because when I use Ableton live or Max the midi channels come in correctly.

    @jameslo, Yes, the order that the devices appear seems to change with the midi channel number. I have a device, that I made, that operates on two midi channels, 1 and 2. It only has one USB cable connection so I can't plug them in separately. So it's kind of arbitrary which midi channel gets displaced.

    Hi,

    This has been a pain for me for awhile. When I plug two or more midi controllers into my Mac Pd will get the correct channel number of the 1st controller, but always assign a seemingly random number to the 2nd channel number.

    I am always on midi channel 1 and 2. Right now my Mac thinks I am on channel 2 and 17.

    I just wanted to ask, because I am switching back between an RPi and a Mac and having to change every ctlin and ctlout object just to work on my patch for a few hours is a real drag.

    If any one knows a way to resolve this please let me know.

    Right now I am on Pd 51.4 and Mac OS 10.13.6

    Thanks, Nick

    oh my god! ha ha. i have a lot of homework to do.

    Hey seb-harmonik.ar, this subdivide object is pretty cool. I had to install the ekext library to get it to work as well. Amazing how this works. I think there is something similar in Automatism that I sometimes use.

    I think between this subdivide object and the modulo method off one metronome I can get what I am imagining in terms of poly rhythms. Thank you both for the input.

    If i make a crazy poly rhythm patch I'll post it here.

    Hi ingox,

    This solution you came up with is really genius. It took me awhile to wrap my head around this. But I realized what you did is how I would approach it if I had to play two rhythms on an instrument. Find the common rhythmic value (16th note, 8th note triplet, etc) and then do groupings of the each of the 2 rhythms. Doing it this way you can have everything coming off one metronome, so it's way tighter.

    I had to add a sound for the common rhythmic value so I could hear the rhythmic relationship between the groupings. I added a 3rd rhythm too, just to see what would happen. You are right , there is a lot of room for optimization. My variation is not so clean, but here it is if anyone wants to look.

    Hi,

    I normally drive my patches in PD from one metronome, have counters selected to that metronome and select the rhythms I want from that.

    What would be a good way to link up more than one metronome, and be able to have them operating at different tempos, yet still synched up? So a 2nd metronome is playing tuplets of the beat of the first metronome. I really want to get rhythms more interesting than multiples of 2s and 3s. And possibly have metronomes at different, but related tempos to get polyrhythms like 2 against 3 or 3 against 5.

    I made a little test patch to get tuplets, but I think It can be tighter. I am using BPM, but I wonder if I should make some kind of converter to sample accuracy to make it a lot tighter.
