thanks for the reply, the roland or dm10 concerns are about my finance head ruling my daydream head for a change. over the years i have spent good money on great gear, only to sell it on again once i fancied something new!!!!!!
That, my friend, is known as 'Gear Acquisition Syndrome' or GAS for short. We ALL are afflicted with that. Sometimes, GAS wins, but usually the finances (or spouse) contradicts enough to keep it in control. Dare to dream, but always let your financial head in on the conversation!
usually, the opposite is true, people buy a low-end kit, and decide it's not enough, and go bigger.
Knowing what you need is key to optimize. Get what you need, and spend what you considerable reasonable.
For you, I looked at the DM5 pro and the USB pro kits, they seem to be about $100 diff in price - the DM5 being cheaper. for that extra $100, you get the Trigger IO instead of the DM5, which considering you are already planning to trigger external sounds, the DM5 probably isn't what you want. I think the IO will be a superior choice as a TMI over the DM5.
