MIDI recording with Yamaha QX 21 hardware sequencer

So, here is my first video about the QX 21 (first built in 1985). I show you how to record in real time and step mode on the two tracks. There is another third track. The original recording will be copied to the third when a track is quantisized. And of course it can be used for copy & paste to arrange a proper song with different patterns or recordings. Let me now if you want to know more about this little sequencer. specs: 2 recording tracks, 16 MIDI channels, MIDI in-out-throu, tape interface, footswitch for start/stop, 1/4 - 1/64 notes with 1/8, 1/16 and 1/32 triplet, 8.100 notes without velocity, tempo control via dial (40-250 bpm) See also here for what a sequencer in general does: http://en.wikipedia.org/wiki/Music_se...
