MIDI is poorly implemented, but this was the first US MIDI synth. It is in ONMI mode when powered up. No effects, but a very simple sequencer. There are 100 patch locations. The raw sound is rather thin for an analog synth, but it's great for strings.
Basses lack punch because of slow attack of envelopes.
So nothing special so far. The real joy begins when you discover the POLY-MOD section and start to modulate the filter or the A oscillator by the B oscillator with different waveforms. I immediately fell in love with this synth when I did this first time. The membrane buttons may cause some trouble, so push them gently. Also the potentiometers don't always work.
