Piano Expander based on Pianotec and Odroid-N2

Intention

• The intention behind this project was to bring the best piano emulation software together with the best fitted application processor module to build a real rugged high quality piano expander for stage usage.
• While reading in the Pianoteq User Forum I have seen some interrest in running Pianoteq on Raspberry PI.
• For my opinion the Raspberry Pi is a nice application processor module, but it is really not good suited for audio applications. You have to add an expensive extension board for getting good audio performance.
• Some other application processor modules are not so well knows as the Raspberry PI, but have sometimes better CPU performance and much better audio peripherals integrated on the silicon or on the board. Therefore there is no need for cost sensitive components to get a usable audio device.
• The Odroid-N2 seems to be such a CPU board. It seems to have better CPU performance (6x ARM 64bit Cores running up to 1.8 GHz) in comparison to the Raspberry Pi 4 - is thermaly integrated into a well designed heatsink which prevents the cores from thermal throttling even at high cpu load.
• In addition to that it is equiped with a high performance audio DAC.
• So - why not using an Odroid-N2 to design an High-Performance-Piano-Expander with as few as possible external components?

Hardware
