Full midi compatible for it's time. The sequencer on board is eight tracks as well. In fact the T-2 has a bank that is identical to the M1's Program sounds. THey cut through a mix strongly. This is a stong keyboard that can go a long way and is durable for the road.
Keys do have to be replaced from time to time.
I did hear they won't be providing parts for keyboards past ten years. I have not confirmed that yet. This a great keyboard to rent or have in you arsenal. I see them on riders from time to time. I do find that people are not famaliar with them.
