OP-XY / Tonverk (beta) Helpers Support

If you find the tools helpful and would like to support, it’s very much appreciated as development comes with costs — but it’s absolutely not expected.

There are two free tools available for the OP-XY and for Tonverk (beta).

Drum-Constructor:

Create Your Own Drum Kits for the OP-XY and Tonverk subtrack (beta)

• Upload your drum sample library (Tested with 800+ samples – works, but performance may lag with large libraries)
• Drag and drop samples from your library into kit slots, or rearrange samples between slots via drag & drop
• Autofill kit (beta) Automatically fills slots if your samples follow naming conventions like kick, snare, etc. – functional but rough beta version
• Trim silence (optional)Automatically cuts silence from the beginning and end of your samples
• Name your slots Add custom names for better organization
• Preview samples per slot Quickly listen to individual samples before assigning
• Play drums via MIDI (Chrome only – beta)Trigger slot samples using a MIDI device or the OP-XY itself.⚠️ MIDI support is currently not available in Safari or Firefox. When using OP-XY: make sure to route MIDI through a MIDI track.
• Cut Wizard Record directly from hardware drum machines or load an audio file containing multiple samples with pauses in between. Automatically detects slices and you can map them to drum slots.
• Normalize all samples (optional)Ensures consistent volume across your kit
• Velocity Layers for Tonverk Subtrack (alpha)
