Shame on me, that point goes to you. I never used any of the mesa cards and therefore simply ignored what those pins actually are named like. But 'encoder.03.velocity' quite obviously mentiones an encoder input and no A/D. Even if he would connect a rotary encoder instead of a potentiometer, he'd probably rather use encoder.03.counts or something and not the velocity... Oh dear, it's been a long day, time for bed. Bye, Philipp
