Why version 2, well, one of the most important features of a self contained space drone machine is a powerful reverb. This is missing here. In addition, the LFO speed cannot go really slow, e.g. over a minute or longer cycle time. This is a real pity when it comes to slow space ambient soundscapes at ultra slow rythm. Other than that, the sound can be very rich, unique, weird, alien, so nothing short of that one, except for the missing reverb.
