ok, i just bought an opcode studio 64x midi interface. whenever i hook it up to my pc, both in and out, the notes stick. when i just have out from my keyboard, to in on the interface , an then out to pc... it works. as soon as i hook up the out from my pc to in on the interface, it start sticking notes again.

any idea why this is happening? if i can't get this to work... i need some sort of midi interface. here is what i need to do:

i need to hook up the in and out of every component i have, to send and recieve midi data from my pc. i have an edirol keyboard, which needs to be able to comunicate with it's cc assign software, a korg ms2000r, a roland mks-50, and a roland pg-300.

and i need the interface to be able to hook up to my pc via midi, so it goes straight to sfp. so, i basically need a device that will bus 4 midi in ports to 1 midi out port, and 4 midi out ports to 1 midi in port? but, i still need to be able to send data to individual devices, which i suppose i would do through channel assignment...

yes, channel assignment is the way to address individual devices.

it sounds like you may have a midi feedback loop. you may have more than one device generating clock. if you have daisy chained synths, do you have each successive device connected to a through or an out? that mioght also be the problem.....

well... i haven't daisy chained anything. i plugged my keyboards out to the ch2 in on the interface, then hook the in and out of my pulsar II card to i/o 1 of the interface. as soon as i unplug the out of the pulsar II, it doesn't seem to stick quite as much. i think the device is messed up.

maybe, but chances are that one or more of your outboard devices transmits midi clock or active sensing, which should be turned off or filtered.

connect scope to the interface internally through the sequencer instead of externally through the port and things should work better.....
