TONAL DROP THURSDAYS // Official Audio Samples

Tonal Drop Thursdays is your weekly sound design resource from @sonalsystem. Every Thursday, we drop a free, original patch blueprint for a specific piece of hardware or software. This playlist features the official audio samples of the weekly drops, showcasing the patch in action (often treated with effects like Output Thermal or Valhalla Delay). Dive in, find your next sound, and then head to our blog (link in bio) to grab the instructions. Build the patch, TWEAK IT, and share your unique results with us! #TonalDropThursdays #FreeSynthPatch #SoundDesign
