Re: Troubleshooting a Theramin Project by Russell Barnes

Just come across this thread. The good news is that it IS possible to get the theremin project going on the latest raspberry pi os, but you need to do some updates, and take account of updated syntax in Sonic Pi. First of all, there is a problem with the version 3.1 Sonic Pi supplied with the raspbe...

Re: TRIM question

I have a crucial 500Gb drive booting my Pi4 via a UGREEN SATA to USB 3.0 Adapter which advertises that it works with trim, I am using the latest RPI firmware to get the drive to boot directly without an SD card. I have set unmap on the drive using echo -n unmap > /sys/block/sda/device/scsi_disk/0:0:...

Re: Sonic Pi 3.1 on Raspbian Buster is NOT complete.

Hm. I would beg to differ as to the educational benefits of OSC and MIDI in Sonic Pi. As a former teacher who used Raspberry Pi and Sonic Pi widely before retiring, (and advising on projects involving Sonic Pi with OSC for A-level students since then) it has a lot to offer. Also, the foundation have...

Re: Sonic Pi 3.1 on Raspbian Buster is NOT complete.

Thanks for your comments, and I can appreciate your viewpoint. The main problem with the current 3.1 build is that although it is a "proper" debian package, it does not include two very significant features of Sonic Pi, namely its support for MIDI and OSC messaging. These add hugely to its capabilit...

Re: Sonic Pi 3.2.0 deb package for Raspbian Buster

I agree that a "normal" package would be preferable. However in the absence of one, surely a binary package is preferable to nothing. The unfortunate present 3.1 package only contains part of what 3.1 should consist of, as it has not support for OSC or midi, and means that even some of the Foundatio...

FAO jamesh Now that Sonic Pi 3.2.0 is released for Mac and Windows PC, and since there has been no built package forthcoming for this version, I have decided to produce one, which seems to do the job. First it is a binary package based on a built image of Sonic Pi 3.2. It is packaged similarly to th...

Re: Qt and window opacity on Raspbian Buster (Pi4) SOLVED

It seems a bit weird. xcompmgr is enabled and there is an instance running according to ps -ae |grep compmgr However Qt doesn't seem to pick this up and there is no transparency.

Re: Qt and window opacity on Raspbian Buster (Pi4)

Oh what a simple solution! xcompmgr wasn't running. Once I started it the transparency worked perfectly. On other linux this step wasn't needed explicitly in the program, and it seemed to be invoked automatically.

Thank you for the prompt to try this.

I am using the new cmake build currently under development in the sonic pi repro. It builds fine and I have a fully working Sonic Pi 3,2 dev apart from the transparency slider in the prefs window having no effect but not causing any errors either.

The black retaining clip for the ribbon cable connector on my raspberry pi camera board is broken and has disappeared. Any suggestions on acquiring a replacement clip to clamp the cable into the connector? Or suggestions for another solution (not gluing the cable).

Perhaps you should discuss it with Sam Aaron directly, as I gather he was not consulted at all over the inclusion of this version.
