nb the mtm chord organ is the same module with different firmware... so if you really want a radio thing you could also search for that and reflash it...

If you need a Radio Music module you can re-flash a Prok Drum module as a Radio Music, as I have. The Proks make a lot of machine noise in the percussion environment so 1x Prok on percussion duty is as noisy as I want my rack.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
