Interesting - if Chordana app is using MIDI protocol alone, then anything it does can be done by any MIDI patch manager. It'd be great to get a full specification of that implementation!

UPDATE: I have experimented some more with the loopback idea, and while not ideal it could be workable. MIDI latency (delay) is there but it's not as bad as I indicated above. I'll post some metrics later, but it looks like it's more like 5-10 ms than 40ms+. Brad, any idea how we get some concrete info about this MIDI implementation? To begin with a block diagram and some explanation of the overall design and intended uses would be so helpful. And specifically, if we can find out : a) is it possible to select stored registration patches using MIDI and/or b) if it's possible to send the registration MIDI messages (the 'swag I mentioned earlier, back into the PX to replicate these patches? I need one of these options to work so I can use loopback and my own registrations live with MIDI patch management. Cheers Chris

Hi Brad, I'm grateful for your speedy feedback - thanks. Sadly it doesn't cheer me up to hear that I should have bought a different model - especially as I thought this model superseded those others (obviously not). I also checked the product manuals before I bought, and it seemed there was a standard MIDI implementation & Mike Martins' demos and forum posts made me think this had more to offer than just the standalone instrument, so that's quite disappointing to hear. I really wish that limitations/features like this were explained in the casio product info. BTW there is a swag of MIDI output on channels 1,2 & 3 when I select a new registration. This leads me to think that there's a lot of undocumented functionality in this thing, and perhaps I could harness this somehow? ( I'd be so grateful for something that works ) I'll try Chordana Play again but I'm not sure it'll make my life easier in this scenario. Kind regards, Chris

Yes, I agree that naming registrations (patches) would be useful too, but it's not what's critical for me. I simply want to 'call up' these registrations, or any of the 700 patches, using standard MIDI control messages. When I 'call up' a patch on the PSX it should a) update the display and b) play the selected sound. I use sounds from different synths for different songs, but I change patches from one place - a Novation SL49 MkII controller. On my computer I use Bitwig and/or mididings as the patch manager/mixer for all my hardware and software synths. For now I'll have to manually adjust the Casio, which is pretty tragic and time consuming. I suppose I'll need to set up all my registrations in order and set up a footswitch too. Not ideal - I'm pretty sure I'll stuff this up in the heat of the moment .

Hi Brad, I'm not sure if this is the official support channel, but it's the only one I could find, so thanks very much for your help! Yep I'd thought of the loopback workaround idea too and have tried it out briefly. I can do this easily, but I'm not keen because: a) it's a much more fragile setup b) I've noticed a lot of latency in the Casio USB MIDI, it sounds to me like something like a slapback echo (between the local voice and the loopback one) , so I guess at least 40ms delay is involved. Of course that could be my computer setup too, but I haven't noticed this much on other gear. I've been using MIDI gear since the early 80s: DX7, TX7, RX11 Korg EX8000, Roland D50, Oberheim Matrix 6 etc. Even a Casio CZ synth (a CZ-1 I think). I think all these instruments supported program change over MIDI so I'm somewhat amazed that it's missing here. It seems like PX-S3000 is just not intended for the live midi environment, which is a shame as it is such a nice board (keybed feel, size and good onboard sounds ). I'd love to trial a firmware hack if Casio engineers could furnish it Kind regards, Chris

Hi Brad, I'm sending to the PX on on MIDI channel 1. My PX is set to midi channel 1, and local control is 'ON'. If I send note messages on this channel they'll sound with the desired voice, but the PX keyboard is still playing the voice selected manually. There's a lot of latency in the MIDI messages too, which I've yet to look into.

Hi folks, I have invested in a PS-X3000 and am really enjoying the sounds and the playing experience. Now I want to integrate this instrument into a live setup with other midi hardware and soft-synths, so I really need remote selection of sounds via standard MIDI (i.e.using Bank Select and Program Change messages). Basically I want to play the keyboard in 'local' mode where the instrument keyboard plays the onboard sounds, AND I want to select those onboard sounds by receiving midi messages from my midi patch manager (mididings, Bitwig or similar) running on my MAC (over USB Midi). When I try this the main 'local' voice and the display don't change, however the program change IS effective for incoming midi notes, so I know the messages are getting through. So I can send PC and MIDI notes to the sound engine, but I can't alter the local setting via MIDI?? This doesn't seem right - I must be missing something! BTW It'd be really helpful to see some high-level description of the instruments MIDI architecture and how this relates to the onboard sound engine. I'm sure it exists somewhere?
