Rocknrolldentist Posted December 23, 2015 Share Posted December 23, 2015 Hi--I have my casio hooked up to a hammond sk-1 via midi. I play the sounds of the hammond on my casio occasionally (not the organ sounds but the extra voices). I switch back and forth with an AB box to allow me to switch instruments in real time. Anyway, I had the casio playing the flute from the hammond, and when I hit many of the casio keys (a little hard) they wouldn't sound at all. This never happened before during practice, when I played through the headphones. Is there a reason for this? Is there something wrong with my casio? Please advise. Thanks.

Jokeyman123 Posted December 23, 2015 Share Posted December 23, 2015 A few questions-do you have both midi din connections, cables-in/out or just the midi out cable to the SK-1? And which sounds are not playing-the local sounds from the PX or is it failing to access the SK-1 sounds through midi, or both local and the SK-1 if you are layering? If you have both midi in and out cables connected-my guess-is that there is too much midi data looping back from the PX5 to SK-1 and back to PX5, it might be causing this-midi din connections are serial protocols and can't always handle large amounts of data if it is looping back, especially since i believe the PX5s sends out additional "high resolution" midi data for dynamics (playing keys hard could be contributing to this-again just my guess). Of course if you only have one din cable-out from PX5s to in of of SK-1 none of this is relevant, this should not be happening at all and could be a PX5s software/hardware malfunction. If you are failing to play the SK-1 sounds remotely through the PX5s midi out intermittently-try turning off "high resolution" setting in the PX5s. The extra midi data from the PX5s could be causing a "buffer overflow" to the SK-1 which might prevent the PX5s from playing the SK-1, if this is what is happening. I have worked on the internal key mechanism of my PX-350 which is pretty much identical to the PX5s and is pretty sturdy-I do not think a mechanical failure is all that likely given what I have seen inside, unless you have consistently played yer PX5s with sledgehammers! Post back if you get this solved. Happy holidays. Quote Link to comment Share on other sites More sharing options...
Rocknrolldentist Posted December 24, 2015 Author Share Posted December 24, 2015 Hello Jokeyman123-- To clarify, I am using one midi cable from my casio out to the sk-1 in. I am completely able to play the local sounds of the privia. This only happened with the flute from the sk-1 played by the privia. And as previously stated, it never happened in practice through my headphones, only in rehearsal when I played semi hard. I havent tried it with other sk-1 voices, but I can. Any other ideas????

Jokeyman123 Posted December 24, 2015 Share Posted December 24, 2015 What are you using for an A B box? Is this for audio or midi? This may have something to do with this. Again just an educated guess.Perhaps there is physical vibration somewhere affecting a connection. Sometimes the slightest intermittent connection anywhere could be causing this. Playing through headphones-no external vibration. Sound system could be causing even a slight harmonic vibration in a shaky connector. Check all physical connectors.

Rocknrolldentist Posted December 24, 2015 Author Share Posted December 24, 2015 Hello again....I just tried the same setup at home--through headphones, with the sk-1 set up to max volume--I played the privia pretty hard but got no cutting out?? Im puzzled? This anomoly happened at different location through speakers, with a diffeent midi cable. Is there anything here that could have caused the problem? Thanks and merry christmas!

Rocknrolldentist Posted December 24, 2015 Author Share Posted December 24, 2015 Hello again-- Im using a stereo AB box called the t-rex polyswitch. I will try to play at home with speakers cranked but I really dont think there was any vibration during the cut-out--I will check all connections though..... thanks---any other ideas will be welcomed!
