How to Install

To install the Trill UGens you'll need to do a bit of work at the command line.

1. First copy the Trill_SC repository over to your Bela using the provided update.sh script.

your.pc> ./update push -n

You can alternatively use scp

your.pc> scp -r Trill_SC root@192.168.7.2:

2. SSH into your Bela (make sure it's connected to your PC)

your.pc> ssh root@192.168.7.2

3. Make a symbolic link inside the SuperCollider extensions directory to the UGen files. *nice to know: on Linux the extensions directory is ~/.local/share/SuperCollider/Extensions

bela> ln -s ~/Trill_SC/ext/Trill ~/.local/share/SuperCollider/Extensions

4. (Not required) Make symbolic links to all the example projects.

bela> ln -s ~/Trill_SC/BelaProjects/* ~/Bela/projects/

Troubleshooting

Errors like these:

Unexpected or no response.
No valid device connected.
1
Unable to identify device

and

Failed to prepare Trill data collection
Failure to read Byte Stream

Check your I2C devices on the Bela:

root@bela:~# i2cdetect -r 1
WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-1 using read byte commands.
