Very welcome update of one of my favorite synths! Although the classic design with sliders seems to me more charismatic, the new GUI version finally works reliably in Ardour with Abique VST-bridge. This is great news! But the modulation range of the parameters remains insufficiently wide, which is noticeably manifested in the insufficient level of the PWM and the filter envelope. As in the old days with cool slider-GUI, i have to use two identical modulation slots for one parameter. But all is excusable to this sound... Thanks for the great free software.
