Hearing aliasing on a analog synth?
If its plain analog than there is no chance that aliasing will occur. Do you mean analog-emulators?

no i mean usally people talk about aliasing in the high freq but it s everywhere in the spectrum,i take for exemple a analog bass vs a vst bass sound .
it s more digital vs analog debat.
and yes crappy vst have lot of aliasing |

not really, as you are going to record to a digital medium, or at the very least go through a digital medium - thereby imposing whatever sampling rate on the analog signal. You have to try pretty hard these days to not go digital at any stage.
I'm gonna maintain that most so called 'aliasing' in synths is grossly misunderstood, and in fact results from rounding errors in uninterpolated wavetables. IE wavtable consists of samples - when these samples move at different speed to system sampling rate the uniterpolated system is forced to round to the nearest sample in the wavetable causing harmonic distortion of the waveform.
Linear or better spline interpolation deals with this plotting the 'inter-pole' values, and therby plotting the exact (or much nearer, anyway) value for any given frequency of wavetable playback at any given system sampling time.
