Yamaha DX-11 questions

I'm considering getting a DX-11 to use as a cheapo master keyboard with the added bonus of some FM synthesis to mess around with.

My question here is: Does the DX-11 suffer from the same problem as the DX-7, i.e. the maximum velocity output being 100, as opposed to 127?

Also, I wonder if the keyboard is prone to problems such as uneven velocity response and such?

Final question... does the value slider transmit CC?

Ok nobody...

What about the DX7 II ?

I know the DX-21/27 both don't transmit velocity although they can receive it on values 1-127. You might download the DX-11 manual and check the midi implementation, just to be sure.

Thanks for the reply! It actually hadn't occurred to me to RTFM :D

As far as I can decipher from the manual, the DX11 keyboard sends velocity data, 0-127.

Thus, it seems to me that in many ways the DX11 is to the DX21 what the Alpha Juno2 is to Alpha Juno1.

The DX11 is actually a TX81Z with a keyboard. That makes it a superset of the earlier 4 ops synths like the DX21.

Yamaha never seemed to bother with keeping any order in DX model numbers!!!

The DX7-II does not have the velocity limit bug.

I don't know if I'm too late here, but I have some insights for you or anyone else looking for information on the matter.

The DX-11 and DX-7 II do not have the same 0-100 velocity problem as the DX-7 MK I. While they can get to 127, it's very hard to achieve a value over 120. You really have to beat on it. You will want to correct the velocity curve with software, as it (while not being hugely problematic) is a noticeable issue.

The DX-11's "Data Entry" slider does send MIDI information, as do the increment/decrement buttons.

Overall, even with the velocity issues, these old DXs make much better controllers than new MIDI controller keyboards, which are known to break down after a couple years' use.
