\transpose of drum voices

[Fernando]

Lilypond newbie here...

Is it possible to use \transpose for patterns written in \drummode ?

I have a pattern which I want to transpose, say, from snaredrum to bassdrum. I
tried with the following example, which doesn't even compile:

    \transpose sn bd {
      \drummode {
        sn8 sn4 sn8 sn4 sn4
      }
    }
(unexpected STRING, expecting NOTENAME_PITCH or TONICNAME_PITCH)

So, if \transpose only works with regular note pitches...
Is there an alternative way to achieve the same effect in \drummode ?

Thanks,
Fer
