Sometimes you want a really "punchy" sound. To a musician, this means a sound with a rapid attack and a quick reaction from the keyboard. To a software developer, this means a sound with a very low attack rate and a very low latency through the synthesizer from the keyboard to the audio output. To make a punchy sound, we're going to use an external USB audio card, and also adjust the sound card settings.

We've been inspired to be creators ever since we got our first Raspberry Pi.  It makes possible so much invention and experimentation for not a lot of money.  One of the things we've wanted is an easy-to-use, dead simple tone generator for using the Raspberry Pi as a MIDI instrument.
Our just-released Organ synthesizer makes it easy for anyone to get started with using a Raspberry Pi as a musical instrument.  Plug a MIDI keyboard into the USB port and play.  Or grab a MIDI file and experiment with different sounds.  It's fun, and it's easy.  And best of all, it was designed specifically for the Raspberry Pi!
