Hello there! (I’m aware this topic has a lot of different stuff in it, but I figured that would be better than spamming multiple different topics at once.)
So first off, Zrythm looks like an amazing project. The current DAW selection that work on Linux for those of us used to traditional piano rolls is…rough, and Zrythm’s layout reminds me a lot of Studio One (my favorite DAW).
I did notice, however, that there was no PulseAudio support. For my own use, I can generally just use Pipewire and its JACK emulation, but I thought that having Pulse support might make for some wider adoption… The patches are here. If desired, I could also take a stab at adding native PipeWire support, though I guess the JACK layer would already cover most of those use cases.
In the process of playing with this, I also made a Zrythm Flatpak. This was initially done just for personal use, since I run Fedora Silverblue where Flatpaks are the primary method of app installation. At a glance, Zrythm used to have a basic Flatpak manifest, though it seems there was some misunderstandings on how plugins worked (or maybe that support just wasn’t available at the time). As of right now, Flathub does have a sanctioned extension point for Linux audio plugins, as well as quite a few available right now (I used Helm for most testing):
$ flatpak search LinuxAudio --columns=application | uniq | wc -l 36
Right now, there isn’t really full support for paid Flatpak apps yet, but if desired, you could likely just have the standalone Flatpak “bundles” (self-contained files that can be used to install Flatpaks) available for download along with the other ones.
On that note, I did have a question about some potential future functionality, just to know if it’s planned or not. Studio One has a really nice feature that lets you duplicate a pattern but keep it linked to the original, so that any changes to one are also applied to the other. This is really nice for stuff like drum loops or harmonies that are repeated across multiple sections of a track. Are there any plans for something similar in Zrythm (if it doesn’t already exist)?
