hi, i think this is, because the delay-object cannot go below a vectorsize of 64. the block~ 1 does not seem to change this... marius

Hi,
coming back to my lineseg~ patch from last week, I have found a small problem with very fast line~ segments. Say I want to make a lineseg~ that goes from 0 to 1 in less than 1.5 msec, this is not possible, because there seems to be a minimum ramp duration in line~ of about 1.4 msec, a limit found by computing "blocksize * 1/samplerate":
64 * 1/44100 = 0.0014512472
Now I tried to reduce the blocksize inside my lineseg~ patch with [block~ 1], but I still can't get ramp durations of less than 0.00145 seconds. I checked this with tabwrite~ing the output to an array and giving the lineseg these three value/ramp pairs
0 0, 1 1.4, 0.5 100
That should go from 0 to 1 to 0.5 but it goes from 0 to 0.5 omitting the 1 unless I cange the 1.4 to 1.5.
Is this expected, or how could I get faster ramps? Or are these
unnecessary
anyway?
kind regards,
