Concerning the SY77's sequencer, it was the first sequencer I ever used. I can't speak to whether it is easy or hard to learn. It is certainly not easier than using a computer! But I do find myself still using it. In fact, on my upcoming solo disc I used the pattern sequencer in the SY77 to control some of my modern analog synths instead of Cubase. It was just faster for me to set up since I am so familiar with it.
It is a 16-track sequencer. Track 16 is reserved for the pattern sequencer. You can dump patterns from the pattern sequencer to a track on the main sequencer. You can copy parts between tracks, quantize after the fact, record in real time or step time, basically do all the major functions any decent sequencer has. The memory is fairly limited; only one song at a time, too. But tempo changes and time signature changes are easy to do. The song above is alternating between a measure of 6/4 and 5/4, over and over. I don't remember how I did it, but it's possible!

In many ways, the AFM of the SY77 is a virtual analog engine, especially with the resonant filters. 32 note polyphony (16 notes for AFM, 16 for AWM), up to 4 parts per voice each with its own resonant filter, EGs for each operator, panning, and filters, etc. Its a highly flexable synth.rickyd wrote:b3, you sure you did not get this from a virtual analog? lol. Talk about FM fatness, jeeeeeez. Fat and just bloated as h**l.
