>>The MidiBox stuff doesn't use a Raspberry Pi - it uses a dedicated processor - the STM32F4 is recommended
Yes, i've been reading something, however i'm considering the opportunity to do some with the Raspi.
That is, using the Raspi Spi channels along with DIO_MATRIX Module as external interface to my keyboard.
In that case, i could use directly the syntetizers normally embedded in a linux distribution.
What do you say about that?
