Compatibility with Organelle Patches?

Second question here : I just bought the hyper pixel screen which is very neat ! As it uses the gpio port, how can I can attach it to the pisound (already using gpio

The screen unfortunately can’t be used together with Pisound or any other audio card for RPi - the screen uses DPI interface which takes up most of the Rasperry Pi’s GPIO pins, even including the I2S ones which is used for audio data: DPI at Raspberry Pi GPIO Pinout

@jazzmess

Is there a common methodology to convert them in PD for pisound, or is it too difficult for a newbie like me ?

You may need to find some of the externals used in the patches, built for Raspberry Pi.

There is a common pattern how Organelle patches are made. Usually it’s possible to just create [catch~ outL] and [catch~ outR] objects, connect them to both inlets of [dac~] object. Also you can connect MIDI keyboard notes by adding:

[notein]
|  \
|    \
[pack]
|
[s notes]

You should dig into Desktop Mother Patch - it implements the ‘Organelle patching interface’ for computers, so by having an Organelle patch open, and the Mother patch in another PD window (but same process), it should allow you to interact with the patch via MIDI and the GUI of the Mother patch itself. (Assuming the required PD externals by the Organelle patch were found on the system)

Internally, Organelle has its own version of the ‘Mother’ patch which hooks up Organelle’s Pure Data patches with the system hardware. It’s a neat design.
