RetroSampler Pro is a lo-fi sample player inspired by hardware samplers of the 90s. It features adjustable sample and bit rates, clock jitter control, low pass filter with drive control and an integrated ADSR envelope. Lowering the sample rate will introduce the sought-after "ringing" effect found in older samplers which is not just a simple decimation effect: the resampling algorithm accurately follows the transposed pitch without interpolation.
The sound can further be manipulated with 3 independent LFOs and 9 possible destination.

To try some of the features, get the free basic version RetroSampler.
