Want to know the polyphony, or any other simple info that is 'need to know' stuff? You won't find it in the SD2 manual. You have to find it in the SD5's manual.
That's a good tip, one that I found out myself a few weeks ago, but it really isn't all that helpful here. There are also key differences between SD2 commands and SD5 commands, check out the drawbars for one thing.
Another thing is that the same SYSEX command is needed to change the effect to Rotary before you can use the CC comand for Fast, Slow or Stop. Easy as pie when using a sequencer program from a computer, not so easy when wishing to turn the rotor on and off from the average MIDI controller keyboard.
I believe this unit was designed for the desktop musician and not really for the working live musician attempting to control it via a keyboard.[/B]
Undoubtedly, even the picture shows it hooked up to a laptop.
Still, even considering that, I've been using it in Live Gig situations (with live band, not as autoaccompaniment) to great results, considering.
Got another Keystation Pro 88 here now, and found out that it cannot send the Sysex string needed to fire the rotating speaker in the SD2 either. Not a kill IMO. Everything else in the SD2 sounds so good and the price is RIGHT. Still a great way to upgrade the sound of some of these keyboards I've got that are still quite functional but contain dated sounding samples in them.
Gave up on the tonewheel organ and leslie aspects of the thing, am resigned that the NI B4 is still what I shall use on those gigs. Was hoping to get away from the laptop, but what the hey.
Still a good point on that SD5 manual, the real hardhead Midiots should definitely download it and use it to find out more about the SD2.
