Hi,
Thanks for all your remarks.
I know it is alpha so there are some small bugs that you may already be aware of, such as saving of samples from some .mod files. The menu becomes greyed out and you are not able to save samples (I'm on a Mac). The only way to save them is to change a pattern or something in the file, then hit the 'X' and try and save (the dialog will appear). It will crash but still save your song. Then you can open it again and save samples. However, I'm unsure how to import these into my own song properly. I tried to select an existing track and import the sample but it doesn't seem to want to import it (unless I am missing something?)
Funny thing about the "greyed out" menus, I'll look into that, I never quite reproduced it, but you're not the first one to encounter it so it is a serious flaw I should correct.
About the MOD, I'm not aware you can save samples yet

, so I don't what you are trying to achieve! Nothing should crash, even in this alpha version, so please can you give me what actions you are doing?
As for the samples, the next-next version will hopefully have all that is needed to export the samples in a way the future MOD player - or any player - can play them. This will be also useful for digidrum playing. But since you have the MOD you are importing in AT2, it is easier to extract the samples from them using a tool like OpenMPT! Any MOD player on CPC will require 8 or 4 bits samples, saves them in a RAW format. But I don't know what player you will use... There are none except the Digitracker from Prodatron (the Protracker from Crown doesn't have any player, to my knowledge).
Not a bad idea for Arp/Pitch export, I'll consider it.
As for the cell export, the future copy/paste option may be enough?
As for the transposition/random option, there will also be an option in a future "toolbox". But don't forget that you can transpose on the fly and in a non-destructive way via the Linker, using the Transpositions!
Thanks for your support!
