Ableton Live MIDI Remote Script / Control Surface

Flyweight · January 28, 2023, 12:29pm

It looks the latest firmware does not work with the remote script.
I think its due to the version number minor field.
Current v3.1 is a major. Should this has been v3.10

RemoteScriptError: not enough values to unpack

        """Set the E1 firmware version.

Ah. Thanks. Will fix tomorrow when back behind my computer.

Flyweight · January 28, 2023, 12:58pm

Great thanks! I tried but failed

jhh · January 29, 2023, 4:04pm

Should be fixed now. I also changed the logic for waiting for confirmation (ACK/NACK) from the E1. This should be more reliable now.

Hi Jaap,

I have another issue running the latest commit.
This looks to be a type error.

def _is_symmetric_dB(p):
    (min_number_part, min_type) = _get_par_value_info(p,p.min)
    (max_number_part, max_type) = _get_par_value_info(p,p.max)    
    return min_type == 'dB' and (-float(min_number_part) == float(max_number_part))

Other plugins do not have this issue.
This is the SSL4000 channel strip. That used to work except the Q control.

could not convert string to float: '-oo'

Here is the offending parameter.

Here the logs.

I asume this has todo with the fix for the Q values that have min / max presented the other way around.

Tried to enable debug (5) but did not see the difference. and didn’t see the actual full value which python uses.
The template does not load for this specific device.

Regarding the device.name class name issue I have not found a way to get the max4live name when using a preset. But the following works for all Ableton devices, Plugins and max4live devices when not using a preset.
I have not yet made device templates so that needs to be tested.

        return device_name

Ok now I am just trying ideas and so on.

What I do not understand I you look here:

And here on children

Was hoping that somehow MaxDevice would get access to the proper name.

  Return const access to the name of the device's class name as displayed in Live's browser and device chain
Live.MaxDevice.MaxDevice.class_nameProperty
  Return const access to the name of the device's class.
Live.MaxDevice.MaxDevice.nameProperty
  Return access to the name of the device.

As you can see I haven’t ate any kaas from this.
Just hoping to bring some ideas to the table.

Cheers

Hi Jaap,

I have another issue running the latest commit.
This looks to be a type error.
def _is_symmetric_dB(p):
    (min_number_part, min_type) = _get_par_value_info(p,p.min)
    (max_number_part, max_type) = _get_par_value_info(p,p.max)    
    return min_type == 'dB' and (-float(min_number_part) == float(max_number_part))
Other plugins do not have this issue.
This is the SSL4000 channel strip. That used to work except the Q control.

could not convert string to float: '-oo'

Thanks for spotting this, that was a silly mistake. The string “-oo” is used by Live to denote minus infinity, but of course that is not a valid float string Should be fixed now.

Yeah, that’s exactly what I found: device_name is the actual device name, unless when a preset is selected. I’ll try to dig in some other remote scripts to see how the reliably get the device name

Flyweight · January 30, 2023, 8:47am

Hi Jaap,

Great thanks a lot. the experience is getting quite smooth.

Curious if you find anything on device naming.
I can ask some questions for hints on the cycling74, Ableton and synthforum if that helps.

As said my Push MK1 doesn’t show the original max4live device name neither.
But PluginDevice works at least on windows.
So If at some point we find out it is not possible we could figure of some meganism where you first load the original max4live or Plugin device (on Mac) and that you can switch to a max4live or vst Plugin preset after and make that the eone does not load another preset.

#Brainstorm
I like the idea of on the fly generated templates.
As you can order the parameters for PluginDevices in Ableton.
Only thing is that switches are always created as a fader.
It would be nice to have a list where you can add the parameters to be created as a switch.
If there would be an additional list where you can add colours you could generate everything always dynamically.
The whole remote script could also be stateless.
Where it will only send one page to the eone.
This page has to only stay in memory which I think is the case already.
That single page could have some navigation buttons to trigger: fetching previous or next page and fetch next or previous device in the chain.
I think this will give a performance boost and also improves the workflow.

Is there anyone who has a controller that shows the original max4live device name on its display? Not the preset name?

Cheers

Tim

phonaak · January 30, 2023, 4:08pm

just installed 3.1 FW and latest Script. Now the problem is again that the “plugin device preset” is not created at Bank6, P2.

Flyweight · January 30, 2023, 4:20pm

Hey @phoneaak I think that the preset isn’t stored at all.
Which not needed anyhow.
Only the Mixer is stored.

Do you see a generated preset for the Plugin Device?

phonaak · January 30, 2023, 5:18pm

the “plugin device preset” is created next to the mixer preset (bank6,p2) if a plugin is “appointed”.
that is, it was like this until now, I saw the “au plugin” preset.
now if I click on a plugin, of course the Script is activated with the upper right button, I see the names of the Ableton tracks, then if I press the upper right button again, it switches to bank 6, p2, but the plugin device preset is not created there .

Flyweight · January 30, 2023, 5:40pm

Ah I seem to see something similar.
When I select a track no “preset” is assigned.
Only when I click on the plugin is the Ableton Device Chain.
And it is then seen on preset 2 bank 6.

Edit: I touched the preset page and now it work…

Wow this is so sick. I now got a SSL channel strip.
It just loads and you don’t have to think much. Jaap uhhh the script takes care of all the values. So in Ableton you see HZ, DB etc.

phonaak · January 31, 2023, 4:51am

I tried all night, unfortunately it doesn’t work for me

Flyweight · January 31, 2023, 7:25am

can enable debug = 5?
there might be hints what the issue is.

what are you trying todo that does not work?

what platform? win, mac

phonaak · January 31, 2023, 7:57am

macos Monterey (last).
Ableton last

phonaak · January 31, 2023, 7:59am

The plugins device not works

jhh · January 31, 2023, 7:59am

It appears that somehow uploading of the preset fails or does not happen. Is a preset uploaded if you explicitly select (click on) a device in Live?

For debugging, set DEBUG=5 in config.py and restart Ableton and send the log.

phonaak · January 31, 2023, 9:47am

i try it afternoon Thanks

phonaak · January 31, 2023, 1:23pm

where can i find the log?

jhh · January 31, 2023, 2:15pm

See the instructions in the documentation GitHub - xot/ElectraOne: Ableton Live MIDI Remote Script for the Electra One

bob · January 31, 2023, 2:43pm

hello,
well done again ! I am very impressed by the update ! I wanted to know if the .ccmap file must be created manually or if the! I’m starting to understand how it works on windows. I wanted to know if the .ccmap file must be created manually or if there is an automation of creation?
Otherwise I can’t import the preloaded ableton device presets created by @jhh into the electra webeditor. Are they protected?
