Yes, everything needed is in the zip file. All you need to do is upload the zip file using the Web Configuration Tool. I gave instructions on how to load PD patches into the Zynthian in a previous post: Adding Pure Data synths ....(and Csound?)
You can skip down to step 5 as steps 1 thru 4 were already done when I created the zip file. I have updated my zynthian several times since I posted those instructions and can no longer create new Banks, so I loaded Lissajous.zip into the existing bank named generative. Please let me know how it goes.
Yes, that is a 7" touchscreen and I recently changed my zynthian from Pi3 to a Pi4 with 2 mb. I haven’t bought any adapter cables yet to try out the hdmi ports but I am planning to in the near future. I have some other visual patches ready to share if the zynthian community shows interest.
