Thanks for a quick reply.

I thought it might be a RAM issue and now that you confirmed it, I think I can very well live with 45 seconds. It should be enough for verse + chorus in 80% of the material I work with. Possibility to choose between four tracks of 45 s or 2 tracks of 90 s might be useful in some cases though... Anyway, like I mentioned already I can easily use a multitracker if I absolutely need more than 45 s.

I have iPod Touch 2G and I'm not planning to upgrade yet.
