Really good GUI, similar to best commercial ones, demonstrates how GUI can help with workflow and usability. Also, the automation concept is powerful, allowing so many parameters to be automated creatively.

This could develop further to something very powerful and leading ... The idea that comes to mind is ... how to combine Synth1's powerful engine and myriad of presets with this open-souce (means anybody/everybody could take it from here) and great UI and make it one.

Could we convince Mr. Ichiro Toda to join forces or ... could somebody develop a patch/preset conversion tool to convert Synth1 presets to at least similar .helm patches. I used to be a programmer and I believe this could be done. Then, it would be the leading free VST.
