This is a sampler project that has a design in CDJ-2000 nexus and DJM-900 nexus style. The look and feel and the GUI have the same style. Sampler based on STM32F746G-DISCO board and pads from Akai LPD8. Replaced RGB LEDs in the pads. The sampler supports Pro Dj Link. It automatically selects the master deck, can receive information about BPM and beat moments, beats from the CDJ. This allows you to synchronize samples with the track on the air, as well as trigger samples without delays using quantize. Samples are stored on a micro SD card, wav format is supported.
