Monomachine and Program change via Midihub

I am trying to have preset D01 of the monomachine activate Midihub preset 1, D02 activate preset 2 etc, though the monomachine sends out PC=48 at preset D01, PC=49 at D02 etc., which is too high a PC for Midihub to read.

Midihub seems to respond to PC=0 for preset 1, that I can send using a different monomachine preset (A01), which I can’t overwrite at the moment.

How do I make monomachine preset D01—D08 / PC=48—55 trigger Midihub preset 1—8? I tried using transform, turning PC=48 into 0 but that didn’t do the trick.

Thanks in advance :slight_smile:

Hey @AndreaT, try this with a loopback if you have a spare input&output

AndreaT_PC_Loopback.mhp

All it does is take your incoming PC, change it to CC so it can be remapped, then change it back to a PC to send it out.


A physical loopback is a trick to send messages out & back to Midihub so it sees them as external events.
(This is needed here cos MH only changes presets via PCs when they arrive from an physical port)

A loopback connection looks like this

If you use MH connected to a PC/Mac you can do this without a cable using the USB ports.


Do File → Append From Preset… to add to each of the presets you need to switch from.

Change your Device → Settings… accordingly

It worked! :blush: Thanks a lot for the tip and for taking the time to program the patch for me.

Hi! It’s been a while since I last used this patch, and for some reason I can’t get it to work anymore. Nothing in my setup has really changed.

My external sequencer is sending MIDI Out to MIDI Port A of the MH. I have made a physical loop.

I’m expecting that selecting the same bank on my external sequencer will switch the preset accordingly, but when I try to switch bank both led lights of port D flash and nothing else moves.

In the MIDI monitor I can see that on channel 16 a Program Change message is being sent correctly (values 0 to 8). However, the preset does not switch on the unit, neither does it recall the editor project.

I also tried installing a previous version of the editor (1.15) to rule out the possibility that the latest firmware would be the cause, but that didn’t change anything.

What else could I be doing wrong?

Thanks in advance!

Hey, @AndreaT

My first thought is that the Program Change bit of the Settings got changed somehow.

Failing that, would you post the .mhd file from your Midihub?

What’s that?

This is basically a collection of all 8 presets currently on your Midihub

create it by doing Device → Export Everything when your MH is connected

I’ll then load a Midihub with that and take a proper look & test





PS. nice MIDI cable; where from?

Hey @resonotter ,

Thanks for your reply.

These are the current device settings. I also tried changing the Program Change setting on the port I’m using and set the MIDI

Midihub Data 2026.02.12 22.13.06.mhd (21.7 KB)

channel to 16, but unfortunately nothing has changed.

The configuration is exactly how I originally found it

Attached you can find the .mhd file. I also tried re-storing presets on the device, but PC doesn’t wanna move.

cheers!

PS: midi cable is pretty sweet for short connections → RockBoard Flat MIDI Kabel 30 cm

…I think I got it, and your suspicion turned out to be right :slight_smile: The device settings got somehow changed, and I have now set input port to D and then channel 16, and everything seems to be fine

PHEEEW

:sweat_smile:

Yes, just tested and PCs happens as expected :smiley:


PS.

I just reloaded my previous .mhd on the test MH and, lo & behold, it reset the Settings to as in your screenshot.
Something to make a note of …

The .mhd file is a complete backup - it contains all the presets and the device settings.

Hi @Giedrius!

I guess the question I had is why such settings have changed out of the blue, while I simply hadn’t used the editor for a few months. I did update it first thing though before using (also firmware got updated), not sure that was the reason

There was a bug in an earlier Editor version which would migrate these settings incorrectly. I recommend to upgrade the Editor first, then the firmware. Currently this sequence is not enforced, but I should probably make it enforced in future versions, to avoid similar problems. :slight_smile:

Right, that makes sense. If I remember correctly it first updated the editor and then the firmware. Something got lost while migrating :slight_smile: I also forgot myself which were the correct settings with this particular “loopback” setup, but I have made a note now, just in case.
