This is me opening my first Synthesizers.com package on July 2005.
As you can see, Roger packs his stuff extremely well.
What was inside? A nice portable cabinet with power source, Q137 Power Interface, Q104 MIDI Interface, Q106 Oscillator, Q107 State Variable Filter, Q108 Amplifier, Q109 Envelope, and a few patch cables.
My first patch: a typical oscillator->filter->amplifier with gain controlled by the envelope.
And this is the first thing I recorded with this system: Modular1 track. As you can hear, even such a minimal setup can achieve a wide range of sounds.
