[chuck-users] ChucK on a Beaglebone Black

Hi, I managed to compile chuck on a beaglebone black (using Gentoo). Most of the example files play well, but there are some files, which produce a somehow interrupted sound. If this would be due to too less processing power of the CPU (ARMv7 Processor rev 2 (v7l) at 1GHz) -- how can I verify it? What else could produce this problem? Best regards, mcc
