Can ambika work without SD card?

All is in the question, (my Ambika is finish but no sound from it…, I don’t have SD card at home…)
Another question, what size of SD card is recommended?

Thanks!

Yes, the SD card is used only for saving/loading presets.

512 MB is already enough. Counting the filesystem overhead, it can already store more than 1000 presets…

Ok, thanks for that 3 min answer
So I will start another discution…
