Can the Organelle’s 4 (left) knobs be re-assigned to control other (initially invisible) parameters, or are they limited and fixed to the 4 parameters that are displayed?
With the Arpeggio patch, for example:
1 = Tempo; 2 = All; 3 = Tone 78; 4 = Decay
Assignment of knobs and other control data needs to be programmed in Pd. Here are some tutorials to get you started!
To program directly on the Organelle, you will need a USB Keyboard & Mouse and a monitor with HDMI input. You can also use a USB WiFi adapter and @thetechnobear’s VNC patch for remote patching with your computer:
