About MSoundFactory :
MSoundFactory will most likely be a never-ending project. Zelda are probably not going to make any further instruments, instead they are going to implement further modules and features into the mighty MSoundFactory.
MSoundFactory currently comes with many presets converted from MPowerSynth and several fully featured instruments, but it’s far from being “ready”. However it can already be used by creative minds looking for an extremely powerful instrument. The only necessary module needed to be added to the first official release is a sampler, so please stay in tune.
