Using controller object to switch patches

[xoanxil]

Get it! Finally it was a silly, but important / I don´t know how it disappeared.

Thank you very much for your help.

Best!

cool, glad you have got it working , happy patching

Hi,

I am trying to switch patches from SD using this as control object:

PC5 works fine. It goes up a number and I can listen next patch and, when it finishes, it starts again. But PC4 go directly to patch number 1 no matter where I am in the index.

What am I missing?

Interested in bumping this for a solution as well. I use a logic/counter with two buttons via incoming midi CC, and only the one that counts up seems to work, but not downward.

Yes, it is weird because with s1 and s2 it works propertly. Lets hope someone can shed ligth on it. In the meantime, could you share how you implement the logic/counter? Thanks

Apologies, I haven't read the full thread but there is a lot of good info in this thread about patch changing

Tutorial: How to change program on Axoloti from external controller!

Hey guys.. I just got around to changing presets on axoloti last night and thought Id share. I managed to get it working, but it took a few hours though... I tried many times first using the controller object.. But that doesnt seems to work here or else I am doing something wrong. And my friend have not been able to make the controller object work either. Great idea, just no luck yet.... I tried using controller object for two different things, but it hasnt worked for me in any of those si…

I personally use patchnames via strings to load patches. It is MattilynMattroes' version of patchloading, and is very effective. You essentially have an init patch that loads on start up containing all your patches. Then in every patch you have a button/controller etc that refers back to that patch and loads it. I use it with an Oled which is fantastic, but the approach is not limited to Oled.....in this thread I go into alot of detail, and give examples about how to do it....

This post by Matt http://community.axoloti.com/t/tutorial-how-to-change-program-on-axoloti-from-external-controller/969/22 is how I manage patches, it's very easy to implement and faultless for me so far, all thanks go to Matt. Basically you have a patch that uploads at startup (he calls it init Malcolm, downloadable in the post) and that patch acts as a repository for all your Patches, in my case I scroll through them on my oled using an encoder and click it to select, Matt from memory uses mid…

The reason I mention it here is that I personally find it the most approachable, least complicated way of dealing with patches YMMV.

Thank you very much reubenfinger. I will try this other approach. Best

You could try a logic/counter2 object it has increment and decrement inlets:

Oh and just a really obvious thought, please forgive me if this has already occurred to you, but with troubleshooting I guess it's best to start with the basics, are the gpio's inverted, ie with a display bool attached does pressing the button trigger green light or the opposite.

Thanks reubenflinger

It seems there is some problem with bankindex object interpreting "-1". I have tried this simulation and it goes up and down correctly from constant number.

But with bankindex, even using debounce objects, it only counts up but not down. Doesn´t matter where index you are always go to 1.

Though I haven't tested it personally, I would recommend Reubenfinger's advice of trying to switch by file name with patch/load fn, depending on how you name your files, you could use a logic/counter 2 attached to a string/indexed for yourpatch000.axp, yourpatch001.axp etc. or the counter multiplexed with some string/c objects attached if the names are different. The Axoloti is really reliable for recalling files by name with regards to samples and tables. It shouldn't be any different for patch names.

If you try this method, remember not to make your patch names longer than 8 characters. Not sure if that includes the .axp part. It goes against my examples above, but that was just for clarification.

Thanks hitachii. Control object was working nice for me using S1 and S2, but since I have not confortable access to them in enclosure and patchindex doesn´t work with GPIO, I am afraid that I will have to take that path. Lets try...
