1.
u need to do yr recording in sequencer mode.
as for how to do it, u can check the manual or
www.korgforums.com or www.tritonheaven.com( look under triton le)
TR is simply a black triton le with sd card and a few(less than 20 ) improved patches. the 'expanded wave form memory" doesnt mean much( to me lar)
2.the SD card is for u to save yr recordings done in the sequencer mode.
better yet, u can download cool programs and combis , save to yr sd card, and load them into yr TR.
and even better yet, the sd card and sequencer serves as a midi player.
with the abundance of midis in the net, u can DL almost any popular songs and play them via the TR.
they may sound dry and cheesy but u just have to change them into yr desired patches, add the effects and save them as .sng instead of midi.
i can only offer some directions for exploration. its such a powerful workstation, u reali need to sit down and dig into it.
after more than 1 year with it, i;m still exploring.
