ReaSamplOmatic5000 (RS5K) is REAPER's native sampling plug-in, designed to play back audio samples triggered by MIDI data. It is highly flexible and can be used for everything from simple drum triggering to complex multi-sampled instruments. Core Playback Options Obey note-offs: When this is enabled, the sample will stop playing as soon as the MIDI note is released (Note-Off message). If disabled, the sample will play through its entire length regardless of how long the MIDI note is held, subject to its envelope settings. Max voices: This sets the polyphony (number of simultaneous sounds) the instance can produce. The rotary control allows for 1 to 16 voices , but you can manually type in values up to 128 for samples that need to ring out for a long time, such as cymbal rides. Loop: When enabled, the sample will loop continuously as long as the note is held. You can also set a Loop start offset to begin the loop at a specific point in the file. MIDI and Velocity Mapping ...
