Tony,
iOs version that I bought about 8 years ago, which I assume has the same soundset was/is $20
Windows version, if I remember correctly was around the same price as it is now...
So to be realistic, they are milking 9 year old cow. Don't get me wrong. In absence of TTs-1 (and Roland is a bit better sounding synth) its still a good deal, especially considering GM issues with new Sonic.
