What's New in jAmpler

1.2

July 22, 2026

- Fixed a bug where the first 0.25 seconds of a MIDI-to-audio render were silent. - Fixed a bug where, when bouncing in a DAW, the instrument was sometimes not fully loaded. - Fixed preset save/load when using a DAW host. - Added an option in General Settings to choose a different pitch-shifting algorithm. Three pitch-shifting algorithms are currently available. The previous pitch-shifting behavior remains the default.

No layering?

Totally thought you could layer these samples. Nope. Everything else is great but not being able to layer samples is a dealbreaker. If you decide to do this I would love this and be happy to buy it.

Pretty alright

I think this is a nice sampler. Though it could do with a little trimming here and there because it takes up way too much space

Decently good UX, colossal filesize

Auto-trim + auto-tune sample a nice feature. Good sample import support. Some crashing / missing icons here and there on iOS 16.6.1, would be nice to be able to delete whole sample folders instead of each sample tediously one-by-one, but overall nice experience. Unfortunately app will spend the majority of the time offloaded due to massive factory sample library, which cannot be deleted.
