Adding a song mode to play scenes one after an other

What is the problem?

The problem is that i can create great sequences and scenes internally with the Polyend SYNTH but that are too short as im unable to chain them into long song melody. I feel limited by the length of the sequencer and can only play them one by one than not chained like a song mode.

What should this feature achieve?

i wish a function that allow me to play each recorded sequences and scenes one after the other with eventually a random play mode internally… A song mode where you can trigger a sequences by selecting pads to each scene.

Are there any workarounds?

The only way to achieve a complete song melody with the Polyend SYNTH for me now is to record several variations of the first sequence than load them one by one to record them on another device of a DAW in audio to chain them.

Any links to related discussions?

Any references to other products?

The functions i was thinking are a bit similar to the NGEN sequencer here : NGEN – Algorithmic MIDI Workstation — Spektro Audio

of the song mode of the Novation Circuit Rythm.
