@svanya I recall an object called [pipe] - not sure if it would help. That's a bit strange.

@CrouchingPython There is no error with your patch, but like you probably know already it doesn't produce sound (your patch send midi out to an external connected software or hardware). Media - Test audio and midi is your friend, it will start the DSP and you can test in / out of both audio and midi.

@ddw_music You can have a quick look at pdmtl abstraction:
https://github.com/aalex/pdmtl

Look for all musical.* might have something there that would help you a bit?

@lacuna said:

• Much more important to me would be making a backup of this forum.

We have backup, but yes I agree that we need to mirror it (what if I die). Like I said it would be a good time to upgrade the solution (nodebb) - there is a bug with this forum (eating all the cpu). I wish I had more time, very difficult these days.

and I could easily embed (using a iframe) the wiki in the forum (adding a icon in the menu opening the page, something like what we did for: https://forum.pdpatchrepo.info/dataflow)

http://pdpatchrepo.info/patches was a good idea, but I don't think I will invest time in it. We have https://patchstorage.com/platform/pd-vanilla/ that is better.

I can "easily" add a wiki on the server, but like I said to @beem https://puredata.info/ is a bit everything (both sharing patch & information). I agree that it's a bit of a mess.

Also it's been a while since I search google for similar information (guides, tutorial, wiki, documentation). I think we should at least list them here in this post (or a new post called "knowledge base" of something similar and then we can see if we need it.

Would also like to invest time in upgrading this forum, we are running a very old version

@tiemget Basically you need to install and configure jack (you will need to open a terminal and use the command line). Like you can see, it's far from plug and play. If you have motivation and time it's doable

1. open a terminal type: sudo apt update && sudo apt install qjackctl
2. find qjackctl in the menu, open it, Setup... choose your soundcard in Interface and start using Frames/Period of 1024
3. launch pd from the command-line pd -rt -jack -channels 2 -alsamidi

Or [mrpeach/midifile] (maybe in deken)
