PSP Rhythm is a homebrew drum machine for the Sony Playstation Portable. For use on the Sony PSP with Firmware ver. 1.0, 1.5 or 2.0.Inspired by classic drum machines such as the Linndrum and Roland TR-series, PSP Rhythm has been created to use the simple, yet effective 16 step style drum sequencer. PSP Rhythm incorporates the use of audio sample playback instead of drum synthesis. PSP Rhythm has been directly influenced by one of our favorite modern drum machines, the Elektron MachineDrum. The most significant is our use of”parameter locks”(as used by the MachineDrum). Parameter locks enable you to change the pitch, volume, balance, start and end time per step to create moving, changing melodies and effects. This control over your sounds will give you much more creative freedom and allow you to not only use drums, but to use instruments in your music.
