Have to figure out how to rotate it DISPLAY=:0 xrandr --output DSI-2 --rotate left works. But when I do that while zynthian is running it looks all wrong and the touchscreen is off.
I went into the display settings of the webconfig and added dtoverlay=rpi-display,speed=32000000,rotate=90 but that did not do anything.
Anyhow, for now just added a dub delay, just wet signal, and it seems to work.
For each individual channel, I can send the track to zynthian, and get just the effect on a return channel.
The project was a bit on hold because I figured out how to send sysex messages to my Eventide H9. And currently building my own UI for it:
Took a while until I managed to rotate the screen Or rather rotate the touch interface and match the rotated screen. And afterwards I found threads about it on this forum. Somehow I did not find that through google
Anyhow. Turns out my live BPM detection via aubio (For my H9 controller software) is always slightly too fast. Have only tested it on windows, will see if linux / the Pi is better at it.
Could for the life of me not find a CAD of the 5” screen anywhere. Modeled it my self and just a basic case with space for some rotary encoders that I want to connect to the pi.
If you are considering building a zynthian, then you may wish to put 4 encoders on the right side, which aligns with zynthian’s hardware / software controllers. We have contol views that have 4 controllers. In older version (V4 and before) these were two on the left and two on the right. Since V5 (with a bigger screen) it is 4 on the right.
I’m planning exactly to build the exact same device. But made it no further than research by now. Glad to here that there are ongoing projects around. If i can help in any case, let me know. I’m am a professional designer and good at building things. Not a good programmer besides a few months with Touchdesigner.
I think it was these posts. I did so many changes over and over again I can’t say for certain what it was in the end.
That sounds awesome mate!
I’m currently spending most of my time on fiddling with my own software and creating a case that would fit it, but also lets me control Zynthian.
I think what I would need most help with is finding effects that are beat / bpm controllable. For example I tried dub delay, but a lot of random effects that are added just don’t know about the beat concept.
I also did not managed yet to install Perfomix. But did not yet spend too much time debugging.
When i started this project i wanted to just build a switchable VST Effect Device. 4 VST banks, switchable, with 4 Control knobs each. And i planned to bypass all of that with the RMX1000 VST Plugin for overall control and bpm detection, since this is what i need most to have the effects like Delay run in sync with vinyl records. I stumbled over the VST - ARM problem and research led me here. Maybe you can try if the plugin works on Raspi 5. You can download for free or hit me up, i’ll send it over. I think it’s also interesting for you, especially the roller and gate effects. And the little beat sampler as well. But some stuff is crap and also the design and handling of the rmx 1000 is totally aweful. So i decided to build my own.
Ah, didn’t know that zynthian is needing special plug ins. Thought these are also just VSTs. But i recommend to look into the rmx1000 plugin. There are many effects that you are searching for. Maybe you can then optimize your search commands with more experience.
Zynthian uses standard LV2 plugins. LV2 is a plugin technology like VST, AU, AAX, CLAP, etc. It is very common on Linux based systems. It isn’t a “special” plugin. It is a different plugin. “VST” has almost become synonymous with audo plugins due to its prolification in Windows, and now Mac DAWs but it isn’t the only plugin format and is not as widely supported on Linux as it is on Windows and Mac. It is technically possible to host some VST plugins on some Linux platforms but we have chosen to avoid the complexity and confusion of this and stuck with the 1000+ FOSS LV2 plugins.
Or rather rotate the touch interface and match the rotated screen. And afterwards I found threads about it on this forum. Somehow I did not find that through google
