I really like what I see there on SM1, even dedicated phase and pulse width (just noticed those are probably for stereo width, not pulse width
The little curve displays under the envelope stages also look familiar, but I don't remember where I have seen them before.
It seems like the developer took ideas from various other synths and made a really nice GUI out of it
What does it sound like in general? Just wondering since you said the sound is different from Hive's...
If it sounds nearly as good as it looks, it will be a success for whatever his difficult name is
