the well known Wiard controllable Joystick is now available for euro.racks via Malekko, the official “Wiard Cloner”. very cool!
imagine a simple sequencer, control X and Y axis via the sequencer and add the third row as time control – there you go – the 8-16 step envelope controls your trimbre radically in analog domain. the joytick itself is automated but can be attached to the module of course.
