This is a crazy idea admittedly, it came to me when i made that post, a keyboard with an extra screen helping with a sequencer could be a tracker. Doesn’t make any sense with granular synthesis does it, but I just saw this thread on one of Tasty Chips early products, the ST4, which was a tracker.
But no, it’s not possible or reasonable. And yet there is a reason for a keyboard and HDMI connection. Odd that they have not talked about those more.
Still
