Hmm. It certainly seems to have got something in a bit of a mess. Some of the error messages seem to be related to the 3.1 version and yet you seem to be also incorporating 3.2.2 I suggest the following. Uninstall sp3.2.2 using sudo apt purge sonic-pi-3.2.2 Uninstall sp 3.1 I would use the Recommended Software entry under the Preferences section of the Main Menu and untick Sonic Pi to do this. Make sure your OS is up to date using sudo apt update sudo apt upgrade Reinstall sonic Pi 3.2.2 by double clicking on the icon of the downloaded sonic-pi-3.2.2\_1.armhf.deb file Let me know how you get on. ---

pretty sure thats what i did 1st time. Before I do this again - does this version now work with arduino usb is that now fixed? ---

I don’t know about arduino usb, but it certainly does see other interfaces like my midi keyboard. Version 3.1 (on Buster) does not however, as it doesn’t support midi at all. ---

I’ve just carried out the following procedure on my Pi4 running Raspbian Buster. ```ruby sudo apt update sudo apt upgrade sudo apt purge sonic-pi sudo apt purge sonic-pi-3.2.2 sudo apt autoremove ``` Then EITHER double click on the icon of the file sonic-pi-3.2.2\_1.armhf.deb OR start a terminal in the folder where the file is located and do ```ruby sudo apt install ./sonic-pi-3.2.2_1.armhf.deb ``` This should end up with a working SP 3.2.2 EDIT I wonder if you had sonic-pi-3.2.1 installed as well at any time. my first .deb file). If so you should definitely purge that too as it is not happy to have both 3.2.1 and 3.2.2 installed at the same time. 3.1 and either 3.2.1 or 3.2.2 together is OK, but not recommended. ---

Hi, did as you suggested but no luck - very frustrating the previous version ran just couldnt connect see the midi arduino. now this version wont even install same error message - can you not see from the logs what the cause is? ---

> [@wro](#): > > This is Sonic Pi v3.1 running on raspberry with ruby api 2.5.0. > Sonic Pi Server successfully booted. Well this log shows you are using version 3.1 NOT version 3.2.2 So you still seem to have that installed somehow. Also it seems to be trying to access fast-osc which is not used or installed by 3.2.2 Do you have an icon Sonic Pi 3.2.2 on your Main Menu Programming section as shown in the pictorial installtion document on [https://r.newman.ch/rpi/sonic-pi-3.2.2](https://r.newman.ch/rpi/sonic-pi-3.2.2) The installed 3.2.2 should reside in a folder at /opt/sonic-pi-3.2.2 You can try running it directly from there using `/opt/sonic-pi-3.2.2/bin/sonic-pi` to see if it works called directly. Otherwise do you have a fresh SD card on which you can install Buster and try that, uninstalling the existing Sonic Pi and installing 3.2.2 as per the installation instructions? I have the 3.2.2 version installed on about 8 different cards and running on Pi4, Pi3 and Pi2 computers without problem using these instructions. ---

I can share your sense of frustration. It all seems a bit odd. Just to double check what is running, could you delete all the log files manually inside the .sonic-pi/log folder (you can leave the history subfolder intact). Then rerun SP 3.2.2 and check the new log files which should be generated. Check whether they still refer to Sonic Pi 3.1. check whether `sudo dpkg -l | grep sonic-pi` lists any sonic-pi packages if so use `sudo apt remove ` to remove them also worth doing a `sudo apt autoremove` after this, get rid of other packages freed up and not needed after the removal. Also worth uninstalling 3.2.2 and checking that it has disappeared from /opt I suppose one other possibility is that your downloaded .debfile was corrupted. You could try downloading a fresh one and installing that. Other than these it is difficult to work out just what is going on on your installation. Another thought what does `cat /etc/rpi-issue` give on your Pi. If running latest should be Raspberry Pi reference 2020-02-05 ---

That gives me something to work on. I’ll do some digging. I am beginning to wonder if I’ve missed a dependency which is normally installed, but which has been deleted on your system. I’ll get back when I have something. EDIT I think it’s missing ruby! try sudo apt install ruby ruby-dev then re-run SP3.2.2 ---

yep! that fixed it - it opens now, now to next step and see if it sees my arduino midi ---

guess i had to be the test bencher ---

Well thank you very much, as its found a glaring potential problem. I’ll fix the .deb dependencies and post version 3.2.2\_2 to replace 3.2.2\_1 Glad we got there eventually. Let me know how it goes with Arduino. ---

will do - appreciate your help so far! ---

Hi see the new version is out that was quick! 😀 what if any pointers or tips can you suggest to have sonic pi see my arduino midi? basically want to trigger sounds or notes depending on the midi key pressed. what is the process to interface the 2? ---

Not sure how your arduino midi is set up. Out of the box Sonic Pi on a Pi4 will see midi devices which use usb to connect midi like a midi keyboard. I also have a pisound board that has standard 5pin din sockets for midi in and out and it will work with those. I came across this arduino project which might be useful to you. > **[Turn Your Arduino Uno Into an USB-HID-Mididevice](https://www.instructables.com/id/Turn-your-Arduino-Uno-into-an-USB-HID-Mididevice/)** > > Turn Your Arduino Uno Into an USB-HID-Mididevice: While building an Arduino Uno based Midi-Controller for Ableton Live, I came across the HIDUINO project ( http://code.google.com/p/hiduino/ ). It allows you to turn your Arduino Uno (or any other... Although I have an arduino uno lurking around somewhere it is not something I have tried with it. I have however built a touch sensitive “keyboard” input using gpio pins and a python OSC server to send data to Sonic Pi which is another possibility. Can you give more details of what exactly your setup is?
