xShadowSoulx | How do you express the concept of ‘used to’?

I was wondering how you would translate this odd tense in English. Such as the sentence:

I used to play in the band.

French and Spanish seem to express this with the phrase: ave abituada de. But I'm not an expert on the Romance languages (even though I am a linguist), so I don't know how commonly this phrase is used or even if its the right way to do it in LFN.
