This plugin now (version 2.0+) features these samples as 7 drum kits each played with varying tools (sticks, brushes, mallets) making for a total of 18 unique drum kit selections within the plugin user interface.

Default Dry Brushes – OCK-DD-BRS

Default Dry Mallets – OCK-DD-MAL

Default Dry Sticks – OCK-DD-STX

Tutorials with Fotis (plugin developer):
* Please note:  part 1 and 2 were filmed using a beta version of the plugin, and part 3 was filmed with version 1.1 – therefore, there may be slight differences compared to the current version,  thanks for your patience and understanding.

Change Log:

1-27-21. version 2.0

-all 18 kits added to plugin

-samples no longer licensed under the Creative Commons license, but instead licensed under the non-exclusive license listed in the terms

11-19-20.  version 1.1

– resampled the audio files to 48kHz with SoX (best settings), which has greatly the reduced overall file size; the plugin now takes up 1.1GB instead of 2.2GB (414MB zipped!)

– sample rate now capped to 48kHz to match the samples; the volume spike problem should now be fixed

– fixed typo on GUI

11-03-20. version 1.0

– release
