Ladies and gentlemen, for his next amazing trick, Wde the Astonishing will make my songs sound good!
One bug I've noticed: The textbox popup for "Set Time Signature" is relative to the currently "highlighted" block - which means that if this block is currently off-screen, the textbox is too, and the UI becomes semi-unresponsive until you press "enter".
Usually the currently-highlighted block jumps to cursor on right-click, but if you're right-clicking the far-left column, the currently-highlighted block remains wherever it was last (which imo is probably a good thing, one of those unintended GUI hiccups that can be utilized for useful purposes, like if you're using the highlighted block as a soft-bookmark and quickly want to open settings or export MIDI without losing your place).
Moving on to the not-bug stuff:
Out of curiosity, is there a way to get some shading in the new sequence editor? It'd be nice to have alternating shades every-four (or every-eight, or even every-six / every-thirteen for the real odd-meter freaks out there!) blocks, when lining things up.
Another "would-be-nice-if" (though I'm not sure if this is even feasible or not within the Buzz engine) is being able to drag the top/bottom edges of pattern blocks to extend pattern lengths. This would be absolutely SLICK
with EnvBlock especially. If the Buzz engine doesn't allow for this, maybe an option in EnvBlock to automatically make a pattern that's the same length as the current loop length? Seems possibly more feasible, since AudioBlock kinda-sorta does something similar.
