Use at your own risk. 9 | 10 | ## How to use 11 | 12 | 1. Install [Raspberry Pi OS (64 bit)](https://downloads.raspberrypi.org/raspios_arm64/images/) on your Raspberry Pi. 13 | 2. Download Pianoteq from [the official website](https://pianoteq.com/), and put the 7z/zip package you got into your Raspberry Pi. 14 | - Or download directly on your Raspberry Pi. 15 | 3. Run the following command in the same folder of the 7z/zip package: 16 | ```shell 17 | wget -qO setup.py https://git.io/JqVD6 && sudo python3 setup.py 18 | ``` 19 | Simple as that. 20 | 21 | ![](https://raw.githubusercontent.com/youfou/pianoteq-pi/main/recording.gif) 22 | 23 | After installed in this way, Pianoteq will run headlessly (No GUI, to get better performance) on every system boot. 24 | If you want to adjust something on it, just double click the desktop icon to open GUI. 25 | 26 | ## What this script actually does? 27 | 28 | 1. Installs dependencies: 29 | - `p7zip-full` - to extract the Pianoteq 7z/zip package 30 | - `cpufrequtils` - to improve CPU performance while running Pianoteq 31 | 2. Extracts the Pianoteq 7z/zip package to `/home/pi/` 32 | 3. Creates a `start.sh` script under the Pianoteq folder, and it: 33 | - sets CPUs to "Performance" mode while running Pianoteq 34 | - runs Pianoteq as a GUI program or headlessly for better performance 35 | - sets CPUs to "On Demand" mode when quit Pianoteq 36 | 4. Creates a desktop entry for Pianoteq, so you can open it easily by clicking the icon 37 | 5. Creates a system service to run Pianoteq headlessly every time the system startups 38 | 6. Set a default resolution so that you can run Pianoteq while not connecting to a display 39 | 7. Overclocks the CPU to 2000 MHz at the 6th voltage level to get better performance as well 40 | 8. Disables smsc95xx.turbo_mode as Pianoteq officially advised 41 | 9. Modifies the "account limits" as Pianoteq officially advised 42 | 10. Checks if you have already installed Pianoteq and can re-install or uninstall it if you want 43 | 44 | ## FAQ 45 | 46 | 1. `Q` Why use the Beta version of Raspberry Pi OS (64 bit) instead of the stable 32 bit version, or Ubuntu Mate (64 bit)? 47 | - `A` 64 bit allows for better performance, and Raspberry Pi OS comes with VNC Server, which saves a lot of work. 48 | 2. `Q` Is Pianoteq playable on it? 49 | - `A` Sure it is. I get a Performance Index of 32 on it. The internal sample rate set to 24000 Hz, and max polyphony is set to 128. No crackles or dropouts. Playing is quite enjoyable. 50 | 3. `Q` Can I try this on other machines / OS version? 51 | - `A` Not recommended. I haven't tested it on other machines or OS versions. 52 | -------------------------------------------------------------------------------- /LICENSE: -------------------------------------------------------------------------------- 1 | Apache License 2 | Version 2.0, January 2004 3 | http://www.apache.org/licenses/ 4 | 5 | TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 6 | 7 | 1.
