Looking for sample slicer plugins

Questions about producing? Ask them here.

Hello, I use the Ninjas2 plugin for slicing samples but the main problem I have with it is that it does not save the slices between sessions, so I either have to do it all in one go, or save the edited samples separately and edit the plugins again to be the way I intended them to be. Is it possible that there would be a sample slicer that saves what was done?

Hi! A built-in sample slicer module SlicerT is available in LMMS nightlies. It's good.

If you use an old LMMS version that doesn't have it yet, try my Sapfir web app (source code) that lets you chop samples:

- import a song as a sample
- chop it with asdf... keys (like you would hit pads on hardware, including pressing the last key again repeatedly to aim for the next slice)
- delete zones that you don't need (zone key + x key)
- trim the unused beginning and end to make a smaller file (b and e keys)
- map the zones to specific note keys
- by default, "a" key becomes C1, "s" key becomes C#1, "d" key becomes D1... - matching MIDI drums
- adjust start and end positions with mouse
- export an .sf2 that you can use in LMMS, Ardour, Helio and other apps that support the SoundFont format
- import it later, tweak it and re-export as needed

Note: it's rather brutalist and is more of a "can I sample and make a full song using just my mobile phone, a keyboard and free software?" experiment. No undo support, for example.

An example of a beat I did with it as one of the instruments: Makepost - 92STVAR1, though my DAW for it was Helio not LMMS because I didn't have a laptop nearby at the time.

I use LMMS 1.2.2, would there be a problem with my project files if I downloaded an alpha/nightly version?
Thank you for the recommendations.

No, not directly, but if you save anything on Nightly, it will not open in 1.22-official!
So you can use everything you ever made in LMMS in Nightly and 1.3Alpha, but projects made in Nightly or Alpha cant be opened again in 1.22-official.
Personally i atm only recommend 1.3-Alpha, because there are still issues that need to fixed in Nightly
