while i'm on a tear, here's an idea for a future Arturia product...
a tiny little box that will have usb connectivity to your computer
a clock to set Master Tempo (or to be externally sync'd to your computer's tempo)
a single dial.. some small buttons (play/shift).. and a small 3 digit 7-segment display to display tempo etc..
it would act as an 8 port USB hub so that you can connect multiple BeatSteps, providing perfect sync (and power) for all units (which can then be MIDI or C/V'd out to various hardware synths etc..)..
and as a general USB hub for other things (SparkLE, etc...)
- would require an external power supply (included with purchase) in order to provide enough juice for all the connected units...
street price... $29.99 ?
I'd buy one.. and then I'd buy more BeatSteps to branch out my MIDI tentacle monster robot.
