no, not when i test on the 'good' card. when playing [osc~] or the
bandlimited oscillators i posted in previous mails, there is absolutely
no aliasing hearable (on the rme-card). i tested all with an
sr=44100Hz. 

there is somethings else, i forgoto mention: when playing [sqosc~] with
low frequencies (<100Hz), it sounds a bit dull compared to a raw square
with the same amplitude and the same frequency. does [sqosc~] not play
the full spectrum in the low area?
