Always use high-quality MIDI cables when connecting MIDI de- vices, and avoid cables longer

than about 15 meters — longer cables can pick up electrical noise that can cause data errors.

Although it has a built-in tone generator, the QY300 can drive external tone generators and synthesizers just like any other MIDI sequencer or music com- puter. You can even combine the internal voices with those produced by external equipment. Connect the QY300 MIDI OUT connector to the MIDI IN connector of a single external device, or the first in a “chain” of devices you want to control. The MIDI THRU connector of the first device in the chain should then be connected to the MIDI IN connector of the second device, and so on. It’s a good idea not to chain more than four or five external devices without the use of a MIDI distributor or “thru box”, to prevent data delays from having an audible effect on the sound.
