Downloading DecentSampler 1.11.14 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally produced by decent|SAMPLES. The software is included in Audio & Video Tools. We recommend checking the downloaded files with any free antivirus.
From the developer:
Decent Sampler Plugin is an application that allows you to play sample libraries in the DecentSampler format (files with extensions: dspreset and dslibrary). The tool allows you to control secondary ADSR envelopes using knobs. Also, it supports modulated panning and modulated tuning.
You may want to check out more Mac applications, such as CROSS-DJ, FuzzMeasure or FretPet, which might be related to DecentSampler.
