This may be a silly query.
I'm thinking about getting a small simple midi keyboard/controller for the Roland MC-505.
I have my eye on the Roland A-500 Pro as a top choice, and the Akai MPK mini as a bottom choice.
These are all marketed for plugging into a PC. But technically, with a midi cable, it should be able to control the 505 right?
Apologies for the noob question.

do you want to go directly into the mc-505?
some mother/ controller keyboards do not allow you to map the sliders and faders they have a fixed midi CC assignment and channel.
But others do , so you can say slider 1 be CC 9 on midi channel 3 for example.
if the keyboard you get does not allow you assign midi. you could always go through a computer and then you can midi map in cubase or logic whatever.
i used to have a midi mapper thing that was a dedicated little box that could be programed by systex , cost a bit though,but very low latency relative to going through a PC,
I'd look for a keyboard that allows you play around with midi parameters of the sliders and buttons and things.
just a thought.

Yes, I want it to go directly into the 505 and assign the CCs manually to control different parts of the machine. For example, have the pads play different drum parts and the sliders control ADSR and some knobs for LFO, cutoff etc....

your mc 505 uses systex to control lots of parameters also.
I used to use cubase for SysEx. worked quite well. but been a long time tho i just remember creating a part on the time-line with a message inside that i would compile from the manual and it worked. thats all i remember.
I notice sustain in the envelope section of the Mc 505 requires SysEx , so it is not a CC , whereas Attack decay and release are CC controlled.
do any of the keyboards you interested in have the ability to configure sysEx?

Novation 25SL looks good and from what i gather can be programed from a computer.novation
sysex keyboards

I'm not sure if they have the ability to configure sysex.
Configure Sysex? I don't know. CCs seem nice and simple. Even the name sysex gives me a headache. Why can't it be as simple as having two values shake hands and be friends?
I'll have to look at the manual again later and make sure.
The novation keyboard looks pretty cool, though I'd like bigger pads for drums.
Thanks, freqy.

i have a 25sl and i like it a lot. behringer bcr2000 also seems to be a popular choice but it's just got knobs, no keys or sliders

i feel the need for some new-skool midi hardware in general. something like the lego minestorms CPU brain bricks. you faff about nord modular style on the PC before uploading it to the brick, which then functions independently of the computer. make 'em cheap so anyone can have five bricks. functions like transpose, delay, merge, split, arp, strip excess parameters, and most importantly an advanced mode where you can put it a few lines of code. they should be able to form a network if you plug 'em together with ethernet cables or whatnot.

thanks for the heads up, freqy.
Sysex in theory isn't actually that complicated, as long as the keyboard supports it. The manual has an extensive list of system exclusive values for things like pitch control, filter, and lfo.

here's something my sl25 does not solve:
i have a sci prophet vs, which is lovely, but also somewhat autistic. communication problems. you have to do most non-binary operations through a single data slider. you press a button for cutoff, then move the slider. you press a button for res, then move the slider. etc. etc. the data slider is rare and costs $30-40 just for the part. getting someone to change it out is much more.
to do parameters over midi, it's just as bad. first, you send a sysex command denoting which button to press (cutoff, res, env, whatever) and then you send another sysex command saying MOVE THE SLIDER.
this drives me mad, as it would be unspeakably epic if i could properly rinse the thing out with live controls. my novation 25SL cannot handle two-stage sysex commands (switch to cutoff, change slider / switch to res, change slider / etc.) and i'm not sure that'd be particularly responsive anyways. does the bcr2000 support two-stage commands like that?
meanwhile, i'm stuck programming it instead of playing it. at least that's fun too.

in max msp you can do anything you want with midi....have multiple midi messages sent in a specific order, at specific times from a single move of a slider or push of a button.
you can design your own max msp midi controller to control your keyboard/tone generator, then use a bog standard physical midi slider/button unit like a BCR2000 to control max.
so:
midi controller >>>max (acts like a mapper)>>> your keyboard.
disadvantage you need a computer turned on...but you dont need your monitor on once its loaded up.
max is fun too.
