That's my demo video, lol. It's really crappy, and Pulse Synth is not as bad as I made it sound
I found that it's much more controllable if I play on neck pick-up with volume rolled out. I believe it would be easier to use PS with passive bass as opposite to my MM Bongo.
Pulse Synth on bass is pretty much one trick pony. It can do square wave and if you set "pulse" on maximum it doesn't cut low end much. But I would definitely suggest putting a filter after it to bring more character. Otherwise I afraid you can be lost in a mix. But this can be said for pretty much all analog synth pedals I played, like Dwarfcraft Robot Devil.
I'd say that the best application for Pulse Synth is playing synthy lead parts with PWM. I would also love if I could control sweep with expression pedal.
