   a friend trying to make a dsp synth noticed that when using a 
   simple 'add a bit at a time' ramp generator, that if you 
   sweep the freq of a ramp generated this way there are horrible
   artifacts generated.... has anyone noticed this with sweeping
   lookup table ramps?

Was this unexpected?    :-)
