The Memory Rhythm SR88 is a recreation of the 1980s Sound Master Memory Rhythm SR88 drum machine. All the kit pieces through the entire travel of the hardware unit's Tone control have been sampled, which allows the user to dial in precisely the tonal adjustments that would have been possible on the original machine -- but on a per-kit-piece basis, which was certainly NOT possible on the original machine.
Furthermore, three "hidden" sounds that the hardware unit was only able to produce in programming mode have also been sampled, allowing access to longer versions of the snare, hat and crash cymbal sounds. These "new" sounds have been given full attack and decay envelope adjustment, allowing the user to create brushed cymbal effects, long snare drum decay tails, and so on.
Requires Kontakt versions 4.2.3 and later.
