20$ bucks for that?!
firstly i commend the application of a user friendly control surface for the complex and otherwise dauntring editors for many of these retro synths. its definitely a necessary thing to get knee deep into editing these beautifully sounding TAE models.
secondly though, you've not really changed anything...and yet still want all this ca$h for each editor! i mean couldn't there be a more elegant solution, ie a more creative approach to the mass of sliders we already have to face in the synths' apps?
good luck
