been into your work for a while in eurorack format, which is unavailable to me now. love it all tho
total noob, don’t know what to do. getting as error when typing text from step 2 into SuperCollider terminal:
“ERROR: Variable ‘xcode’ not defined.”
is anyone able to help me understand what to do? please?
thanks all
The instructions in step 2 must be entered into the terminal, not the SuperCollider editor.
…i’ve tried command prompt, terminal in VS Code, and command line in SuperCollider, all produce error messages when attempting to run the first line i type in (typed or copy/pasted), as below:
C:\Users\alche>xcode-select --install
‘xcode-select’ is not recognized as an internal or external command,
operable program or batch file.
i really don’t understand what i’m doing wrong and how to start problem solving
sorry, just wanting to play around with this
Judging by how your terminal path starts with C:\, it appears you’re on Windows.
XCode is Apple’s developer environment for MacOS (and other Apple products), so that’s unfortunately not going to work, even if you’re on a Macbook – you’ll have to reboot into MacOS first to run xcode-select.
More broadly, the MultiTouchPad plugin for SuperCollider is based on TongSengMod, which uses MacOS specific frameworks for reading Macbook touchpad data. As far as I’m aware, there’s no TongSengMod equivalent for reading Macbook trackpad data Windows; MultiTouchPad is only supported on MacOS. (Surprisingly, that isn’t obvious).
(I’ve found some open-source driver code for the Macbook touchpad from which someone with the right knowledge could possibly make this work, but it doesn’t exist yet.)
ah, ok
that’s a shame, but at least it narrows down the causes of the issue. thanks for your help
Hi all! Has anyone had an issue running this on the new Macbook Pro with an M1 Pro chip? I’ve got the script running, the UI panels launch, but it doesn’t sense my fingers touching the trackpad. I see no graphical indication or console logs of my fingers moving, and no sound generated either. Anyone experiencing anything similar?
Same here. I will try the midi midi version posted above and see if this changes anything.
makes me wish i had a touch sensing yoga mat to pair with it
That’s an insanely great idea!
@tmarasco125 What’s on the console log?

Besides that nothing…trackpad doesn’t react
Have the same issue with MacBook Air with M1
Hi, all. I’ve been installing Supercollider, git and their dependencies on an old MacBook Air running High Sierra. I got all the way through to launching the IDE & running the sections in the .scd file. The SynthDef () portion appeared to work, but when I ran the section below line 85, I got a bunch of Class not defined errors, I’m guessing for MultiTouchPad. Even though earlier the GUI had stated MultiTouchPad installed.
Any ideas? I’d love to get this app working! Thanks in advance.
what errors did you get exactly? can you copy/paste the supercollider console log?

mmmmh. i can’t really make heads or tails out of it. Wild guess would be that the mulittouch library was not installed properly
Ok, thanks. I’ll do some digging and maybe redo it. I am not a programmer really, so I’m flying blind a bit here. 
Hi! list the steps you did so we can see what was done/wasn’t done. There are a few lines to run to get it working.
It’s amazing how often rebooting fixes your problem. 
It’s working now! Thanks for everyone’s help!
Are you using a M1 Mac or an Intel version?
It’s an Intelcore i7. It’s an old Air from 2011. But, it works now, so happy days.
