The Tiptop Audio ONE (x4 pack) is a digital audio sampler module that is compatible with Eurorack modular systems. The ONE plays back samples via SD card with super-low latency. The ONE includes a pre-loaded SD card with a set of 60 sounds designed by Glitchmachines. The primary operating mode of the ONE delivers pristine, transparent 24 bit/96kHz playback via the trigger button on the front panel. The pitch control allows for fine tuning of the playback rate that emulates vibrato and tape speed effects. The CV input can be used to sequence through files on the SD card. The ONE can also play CV signals from the SD card allowing a whole new realm of control possibilities. The front panel also features a Gate In jack and an Output jack. This item consists of 4 separate Tiptop Audio ONE modules.
