Hapax VS Pyramid SEQ mode

Hi there. I wonder if there is the same fonction on the Hapax than the SEQ mode, with allows me to use a lot the Program Changes on various gears (that I use transport OFF. I like to change styles and arrangement without waiting for the end of a pattern loop. Mutes, PC’s, evolutions ,are then strongly programmed. It’s also a way to have only one machine that controls the others. No problems of remembering where is what, on long live perfs.

I guess the only way to do so (with the Hapax), is to use as many Projects necessary.

But is it possible to “call” a project freely, and having the loop (or the ‘scene’) starting immediately ? Is it possible to triggers the projects like this ?
