Raspberry "Pianoputer" ?
Posted: Wed Dec 10, 2014 11:43 am
Hello everybody !
I'm learning piano (near total noob).
Here is my current "Biography" http://linuxmusicians.com/viewtopic.php?f=12&t=13215
I wonder if attempting to create a Raspberry Pi "Pianoputer" is a good idea ?
Here is my knowledge about the hardware :
- Poor audio output ? (I heard about PWM / only one bit etc)
- Limited computational power (captain obvious )
- Low memory
- Low consumption
- Linux available
So far, I know it's a capable machine for playing MP3 / Video etc.
My "SkilZ"
I can tweak, search, try, solder, code a lil'bit of this and that (Python and Co).
I'm already a hobbyst with Arduino stuff and I've some Raspberries ready to go.
I have a 88 keys midi keyboard and needed speakers / amp etc.
My goal :
- Create a tiny computer, a kind of "midi expander" dedicated to piano.
- If the sound is "average" it's already very good for me.
- Latency must be very low
- It must be able to run a sampler and a kind of tiny deamon for showing what note is played (coz'I'm'A'noob)
My ideas so far :
- Using a DAC in order to shortcut the internal audio : I heard that the RaspPi can't do "massive" polyphony, can I solve the problem with a DAC ? (I think I'll shortcut the RaspPi's PWM stuff with a DAC ?, it's a kind of audio card in fact ?)
- Using a Linux piano sampler and samples with small footprint (something like that ? http://linuxmusicians.com/viewtopic.php?f=50&t=12046)
- Use a very simple Linux distro when the setup is Ok... launching the sampler when starting the card, use GPIO and a button in order to turn off the beast etc.
- Use a "car rearvision" TFT monitor, cheap and tiny (I'll tinker for soldering and so on)
My fears
- Massive latency ? I have no idea how it can perform...
- Not enough memory... 512Mo...
- DAC not improving something...
- Jar Jar Binks in StarWars 7 (or any kind of stupid sidekick )
Any guess and tell is welcome
May the force be with you !
