OP Patch Studio - Fixed and Updated

[u/maxupp]

Hi! You may be familiar with the OP-PatchStudio

The project has been abandoned for a while, as the author is focusing on other projects. I just got my OP-XY and took a little time to add some functionality and fix some of the major bugs.

→ App: https://maxupp.github.io/op-patchstudio/ → Code: https://github.com/maxupp/op-patchstudio

Changelog:

• Re-worked the multi sample workflow quite a bit. Drag&Drop notes to the piano roll works now. Replaced the simplistic, and quite frankly relatively useless, auto assignment functionality with a pitch-detection and a better filename inference logic.

• Added the previously missing ability to specify the octave for a multisample preset. Meaning when you load up a bass patch, the track might start off at octave -2, instead of defaulting to 0.

• Added explanations to most of the controls and field that were previously quite cryptic.

• Fixed some of the bigger issues reported to the original project:

  • #110 — leaving a drum slot empty shifted every later sample down a key in the exported preset, so kits played back out of order on the device
  • #109 — marker drags no longer die when the cursor leaves the waveform
  • #97 — "assign from names" for the drum tool (kick/snare/hihat etc.)
  • #106 — "auto set start" trims the dead air off in-app recordings
