Hi there,
I would like to upgrade an original QS6 to OS ver 2 to allow the smf
playback option from PCMIA cards.
Does anyone know where i can get one - have tried emailing Alesis but there
is no answer.
I'm in the UK by the way.

I'm a german user and made good experiences with the german local support (display replaced). Maybe you try the UK support ? See "dealers" on www.alesis.com
