Dom,
I just wanted to run a suggestion by you and see what you think of it. In your statement you mentioned you dont really care for the arranger and how powerful the MS is as a synth. Keeping that in mind you actually have a good chance now to tap into the market with something that no one else is doing, BUT this feature has been requested MANY times from all the synth makers.

Lets go on what you said about not really being too interested in the arranger. Well for YEARS synth players have been asking for the ability to have preset drum patterns that are triggered like an arranger keyboard. I agree the MS is a freakin beast when you look at it's power as a synth..., but you could tap that market for those who have been wanting to have 100's of preset drum patterns with dedicated controls like an arranger keyboard. I can't tell you how many times I've read requests for this feature. You could then just find a really good person at writing the drum patterns.., you could even go as far as making it several tracks.., and even leaving one OPEN for the user to record their own bass line to be triggered like an arranger.

Anyways..., just a suggestion.

Best Regards,
Squeak
