He was brought in by Vieux Otis, a friend of the founding members [citation needed] as a drummer for the pop section of the group.
After two years in the band Ombale decided to shift both role and genre, changing from drumming to singing and pop music to Soukous.
[citation needed] Shortly after Tabou National began performing, Zaiko member DV Muanda asked Ombale to rejoin the band.
[citation needed] Rising tensions in Zaiko between the frontman and the instrumentalists led to their decision in 1975 to oust Evoloko and the singers in favour of Ombalie and Nyoka.
Ombale became the creative heart of Zaiko, writing numerous songs and fronting the band in Nyoka Longo.
However, a developing rivalry between Ombale and singer Mashakado Mbuta over band leadership came to a head at the end of the year during a live performance on Zairian national television.
With a stable lineup, Ombale entered an artistically fruitful era, as Zaiko released songs of his including "Ima", "Likamuisi", "Aziza", "Moni Amina", "Amitie", "Lolita", "Misolina", "Cherie b wabi", "Kinshasa makambo, " diakina", "didina", "youyou" and many more.
At the beginning of 1980, worried that the large number of musicians meant that the band was losing cohesion, Ombale, Nyoka Longo, Teddy Sukami and DV Muanda decided to suspend all the singers and requested all to reapply for their position.
Other Ombale songs released included "Mopaya zoba", "Baby", "Elima ngando", "Sandralina", "Fanny moke", and "Nibe ya bomwana".
[citation needed] Karlito performed in Basilique Loningisa as a guest and featured in all songs and albums released by the band.
