Quasimidi Quasar #1 Dreamy Ambient Guitar Patches

video upload by Kosmokatze

"Some of my favorite Guitar patches of an early 90s Rack-Rompler.
I think it still has charm in terms of sound and some really nice Patches on board.

Do you still use a quasar or an old rack rompler for your productions?

Hydrasynth Explorer // No Talking // Knobcon 2021

"5 quick minutes with the explorer!

My thoughts briefly, doesn't feel like a compromise, just feels more compact. Keys feel nice, remind me of the Yamaha reface keybeds.

Poly aftertouch has a well tune travel, feels responsive."
