A real-time MIDI synth editor that allows you full control of every parameter of the sound on the Waldorf Pulse.
Looks nice but a bit pricey at 70 clams. I’ve made an X-station map and it’s working nice, but I need the precision provided by a software editor. That said, there are not many parameters, so I could knock something-up in Synthmaker.
On the other hand, there is this free (non-VST) editor from Granucon.
Having lots of fun with the Pulse – very expressive monosynth that begs to be tweaked. The filter sings!
