Retrospective histories place the MP-5 in 1966 or 1967. Its compact transistor-based design belongs to Keio’s early Mini Pops family; a dated original announcement has not yet settled the introduction year.
The wider Mini Pops family

FACT’s retrospective names the MP-7 in its account of Jean-Michel Jarre’s Oxygène. This supplies wider Mini Pops family context, not an MP-5 recording credit.

Jean-Michel Jarre / Oxygène
Jarre recalls that the only drum machine in his Oxygène setup was a Korg Mini Pops, whose preset rhythms he combined with Sellotape for Parts IV and VI.

The smaller MP-5 and larger MP-7 put Keio’s electronic accompaniment into compact boxes. FACT’s retrospective describes the MP-5 with ten preset rhythms and tone, tempo and volume controls. Its economy is the point: select an accompaniment, shape its overall sound and place it beneath a performance. The preset supplies the pattern; the player supplies the song.
The MP-5 and the family around it
The MP-7’s twenty rhythms and separate percussion faders belong to the larger model. Its familiar association with Jarre’s Oxygène should not turn into an MP-5 recording credit. FACT explicitly names the MP-7 there; Jarre’s separate account names a Mini Pops without resolving the model. Both illuminate the family while leaving this smaller instrument’s recording history open.

Before the model histories settle
Retrospective accounts place the early Mini Pops in a 1966/67 window, during Keio’s move away from rotating-disc accompaniment. A dated launch document is still needed to settle the MP-5’s own introduction. The later Mini Pops Junior has its own page and recording credits; a shared family name does not make it interchangeable with this model.
