"The Joy of the Preset-Synthesizer. First battle is Roland SH-1000 vs SH-2000!

I like Preset-Synthesizer. An engineer made sound with analog technology at the time without the sampling technology.

It was often that I heard a sound different from the displayed name in them.

I often thought "Is this the sound of the piano?".

But I can imagine a desperate face of the engineers who are going to make a genuine sound with an analog circuit.

It is very exciting/humorous for me.

Roland SH-1000 is Japanese first synthesizer and SH-2000 is Preset-synthesizer for organist.

I love them! Please enjoy!"
