How to use patch banks and controller object with s1 and s2 buttons

[philoop]

i want to change patches from SDcard, using the two hardware buttons.
I made this controller object and enabled it.

I then created a patch bank, and uploaded it to the SDcard

Whatever i do the "on sdcard" remains blank...
do i have to rename the folders like folder000 folder001?
Can someone please explain how it should be done?

The "on sdcard" column remains blank in the current implementation.
I believe the plan was to indicate if the corresponding filedate on the sdcard matches the filedate of the patch, and skipping patches that already are up-to-date on the card, when doing a bulk upload. But a patch bank bulk upload hasn't been implemented yet.

There should not be a need to rename anything on sdcard. After creating a patch bank, you need to select patches in the bank and press "Upload" (bottom right button) one-by-one, and "Upload bank table". References in the bank table are by name, so re-ordering, adding and removing patches does not require re-upload of the patch.

Known broken in the patch bank editor is that it will keep asking to save the patch bank file.

thats what i did ...i tried this object http://community.axoloti.com/t/patch-bank-and-midi-program-change/1078 and my object none of them work

[johannes]

What is failing?
Are the patches effectively written on the sdcard (each patch in a separate directory, directory name is the name of the patch, inside the directory, there is a file patch.bin)?
Is there a startup patch (start.bin) on the sdcard?

[philoop]

Yes!! does the control object have 2 be an axo or is axs?... i think i will format the card and start from scratch

[johannes]

The control object needs to be present in a library, you should be able to locate it in the object selector. If it's a sub-patch (the common scenario), it's .axs

yes
i made the controller patch the start.bin...
if i press my button,
Axoloti says: file error: FR_NO_PATH, filename:"/2randomsaws1"

[johannes]

What's the name of the patch you're trying to load?

[keyman]

this object http://community.axoloti.com/t/patch-bank-and-midi-program-change/1078

This works from a long time now

I think its the path to the actual *.axs file that tricky. @philoop please make sure its correct; when you run LIVE a patch check console:

Using controller object: ..............
Generate code complete
Start creating directory on sdcard : .........

one question : how is the conrol object applied to patch?will it be written to the patch.bin?automatically?

Yes its automatic some more info: http://community.axoloti.com/t/how-to-use-controller-object/910/3

Will try your patch (using buttons S1 /S2)

Don't give up

[philoop]

hi keyman, thanks for stepping in! i use now ur patchchange object and the console says

Using controller object: C:\Users\Philoop\Documents\axoloti\objects\controllers\patchchange.axs
Unable to created controller for : C:\Users\Philoop\Documents\axoloti\objects\controllers\patchchange.axs

[keyman]

yeah, its not picking up the controller patch ;-( let's debug that...

[keyman]

OK so, in Preferences - Controller object - only enter: controllers/patchchange
So no extension for the file.

Click OK, and don't forget to: FILE - Reload objects

[philoop]

Thank u very much i finally got it working----

[keyman]

Great to know @philoop !! and this using the buttons S1/S2 or MIDI program change??

Would be nice to combine both ways (sending MIDI program change AND also use button S1/S2 up/down)
maybe it can't be "combined" ?

[philoop]

your object worx really good....but

and this using the buttons S1/S2 or MIDI program change??

no i am still working

[johannes]

Looking at your first patch: the counter object will lose its value and not be able to increment to the next patch after the first. The controller object is only integrated in patches, objects will not preserve their internal value while switching patches...

[philoop]

aha !!! thanks !! is there a work around ? if not i am doomed to use a pot or decoder, actually what i want do is to have a dual segment displaying 100 presets, i have also be playing around with the 74HC595 recently....
and yes i could only switch back and forth between two patches

[johannes]

There is currently no work around.
I think the closest and cleanest solution 'd be adding a function to the firmware to get the patch index of the currently loaded patch.

[philoop]

i thought about that too reading this

Get number of patches stored in patch bank on sdcard

I want to change patches with a rotary encoder. For that, I use a patchbank and the load/i object. Changing patches works so far, but i need to access the number of patches stored in the patch bank to implement some further instrument change logic. I don't want to store the number in a controller object but rather read it at runtime. I found the function "LoadPatchIndexed" which is called by the load/i, and the c code in patch.c which parses the index.axb file. Although I know basic c/c++ coding…

Problem solved with the new controller

Patch Changes and File structure in sd card

I have added an object "patch/bankindex" to obtain the index of the last loaded patch via "patch/load i"and a few ready-made "controller objects", for version 1.0.10, you get them via "sync libraries".

"controller/select patch with potentiometer": connect a potentiometer to PA7 to select 16 patches
"controller/cycle buttons" : use switches S1/S2 to go to the next/previous patch in the patch bank
"controller/pgmchange" : use midi program change to load a patch

and a simple patch bank for testing, in axoloti-contrib/patches/jt/patchbank-test

Enter the name of the selected controller object in preferences, open the patch bank in axoloti-contrib/patches/jt/patchbank-test, in the patch bank window, press "Upload bank table", and "Upload" the patches one by one. Still you need a start patch: create a new (blank) patch and select "Upload to sdcard as startup".
