I was very excited that the XW-PD1 had the Solo Synth and almost purchased a used iPad while waiting for the XW-PD1 to be released in expectation that the XW Midi Designer could be used with it to control the parameters of the Solo Synth. Since that isn’t the case and it appears that this won’t be changing in the future as there isn’t user files for saving Solo Synth sounds I truly wonder why the Solo Synth is a part of the XW-PD1. As it is, the Solo Synth seems nothing more than PCM waveforms to me but hopefully I can be enlightened otherwise. Currently I am thinking that it would have been more beneficial to have included 100 more PCM Melody waveforms than including the 100 sounds of the Solo Synth. This would have also eliminated the restriction of the Solo Synth only being used in Bank 1 as the PCM Melody waveforms can be used in any of the 4 banks. This isn’t intended to be criticism of the full blown Solo Synth. I was expecting the full blown version in the XW-PD1 and couldn’t wait to tweak sounds on it for hours on end as I think very highly of its flexibility and really like the way it sounds.
