Hey folks,
I build a pure data, raspberry pi drumcomputer/synthesizer. The DAC is a hifiberry with extremely low latency. I used korg midicontrollers and it worked wonderfull. But now I am trying to get into my custom midi controller and start to learn arduino.
I followed this fanastic resource (https://github.com/alexdrymonitis/Arduino_Pd) and also read the Arduino for Pd'ers-Guide which was very good guide an helped setting up a first test. I connected two buttons and it works good but it has a horrible latency. It isn't my soundcard. But it seems that the serial information comes with a delay. Does anyone have an idea?

Cheers,
Johann
