Tag Z-LiveRec

Raspberry PI official launched the new Bookworm version of the Raspberry PI OS 2023-10-11 and I immediate had to test if Z-LiveRec was working as usual in this new version. Raspberry have done a couple of changes in the audio support for ALSA and also to VNC Server. (It is replaced by another vendor) So I was suspicious if things had stopped to work – But I can happily announce that the new OS seems to work as expected! There are some issues to get 3.5″ touchscreens to run in this new OS (Generic problem – not solved yet by raspberry.org) but the official 7″ touchscreen from Raspberry and also from the vendor Waveshare worked perfect after been running a rpi-update to get the latest kernel #5622.

For the Waveshare 3.5” touchscreen using SPI – I raised a support case with them and they promptly replied that they are working on a new driver for their screens and Bookworms – so stay tuned here!

One bug which have been annoying me for a long time in Bullseye(With a lot of error seeking) is that graphics objects (like buttons, text and graphics) have stopped to update when running the app – which was creating big problems. But these problems was suddenly totally gone in bookworms – and I am guessing the newer version of the graphics library TKInter, used by Z-LiveRec, have been updated and also fixed these experienced problems.

So I made a short recording with Z-LiveRec from my A&H CQ20B mixer in 96KHz, 16 Channels in 24bits…and there was absolutely no problems here! Works like a charm! 🙂 The only function which currently is not working is the included VNC server implementation in Z-LiveRec. (So I am going to fix this in V2.28)

Another nice experimental feature in the upcoming version of Z-LiveRec V2.28 are support for OSC calls – so you will now be able to control Z-LiveRec remotely from softwares like Bitfocus Companion etc. And it is real nice to be able to start recording over the network by using a stream deck.

News and changes in version 2.27

I must first confess that not all new functionality works directly as expected. In the 2.26 version we introduced our first implementation to be able to use Z-LiveRec virtually from any VNC Client (like an iPhone, iPad or Android device) connected to the hosting Raspberry PI with a multitrack mixer attached over USB. But our first attempt was not 100% – But in 2.27 we have improved the implementation a lot – to make the remote experience perfect – just a checkbox and the functionality is up and running. In this new version you will also find many other improvements and fixes.

Have a look – and please check the new version out!

• Fixed a problem with the filename dialog, so that pressing “Cancel” will abort the recording process.
• Changed the filename dialog when running remotely in VNC – so the focus maintained and can be editable.
• Addressed a problem when toggling between hardisk/storage devices when in touch mode.
• Added a function so that a VNC session terminates when the VNC client is stopped.
• Added a function so that a VNC session restarts after termination of a VNC Client/Session
• Added so that the VNC Session uses the actual user at the VNC Host and be created in the user’s home directory.
• Added a function to determine if Z-LiveRec is running in “Host” or in “Remote” mode. Visible in the GUI frontpage – “Host” or “Remote”. (The actual IP address can be seen in the license page)
• Added a shutdown dialog to give options to reboot or only shutdown the system.
• Investigated and found the issue why Bullseye have disappearing taskbars when attaching multichannel ALSA Sound Cards. See separate post at Z-LiveRec.com – Not implemented in Z-LiveRec – this is an OS patch.
• Fixed a problem seen in PI OS Bulleye – Where Z-LiveRec did not store/read the saved hardisk path.
• Updated the GUI on the license page/dialog.
• Added a process to handle terminations of a Z-LiveRec window – like pressing windows “X” when not running in touch mode
• Checked so that the autostart process uses the right credentials when created on the system.
• Both 32-bit and 64-bit versions are available for both the trial and full version.

Check the Z-LiveRec V2.27 Manual for more information and details.

A free update is available for registered users (Login to “My Account” and download the latest edition or use the e-mail download link from the original order acknowledgement) and free demo/trial version is also available for everybody else to try the app!

Please note: Using the auto update function in Z-LiveRec (for registered users for the 32 bit version.) – You will find a zip file in the PI/Home directory – and you can just extract the zip file yourself – and the V2.27 version will show up.

The update process will try to unzip Z-LiveRec and overwrite the old version of the app – and a chmod r+x command can be required to get the V2.27 version to run again. See the manual for more information.
