When starting yosh without any instrument/parameters, there are clicks/plops/pings on note on. Not surprising of course, due to the short default amplitude-attack times and near sine default waveforms. What I do notice is that for SUBsynth, increasing attack time to a value of ~10 is sufficient to remove note-on clicks for even moderately low frequencies, as should be expected if the unit is [ms]. For ADDsynth and PADsynth in contrast, a value of >35 just barely silences the somethat 'plop'-like attac sound. The same for release times. Naively asking my ears, I'd say those plops are not tied to the attack ramp of the env, the ramp just decreases the volume of some plop, irrespective of the note frequency. I find this not to be audible (or perceived as part of the characteristic attack spectrum) for most patches with significant HF content. This is no different in Zynaddsubfx. Not sure about any repeat echo. best, d
