Cool knobs.
"Put together this Sound Gen to mix some of the effects this puts out. There's plenty of combinations and switch settings to change the freq's output. This came in handy when sending a signal into some of the sequencers I built and changed the sound completely."

"This has many settings to change the frequancy of the output. You can run in into an amp as you can hear on the video below.

There is a left side and a right side control on this unit. The left side and right side has matching setting with independant controls and a center control switch that will blend and completely change the settings of both side generators.

The push button controls will work as pulse channel settings or you can flip the switch to stay on all the time. The blue knob controls will adjust the frequancy and give you a wider setting when you use them. The upper controls are in Yellow and Orange. Those controls will allow the pulse and timing controls to offset the frequanies and change the way the "raise and fall" of the tone, this will also adjust for some strange filtering effects on the output.

There is a ring adjustment that will blend both sides and giving you full control of both the control adjustments. Those are the "Blue" control settings.

On/Off switch will turn on or off this unit, along with a green LED. (Center)

Power supplied to this is a 9Vdc voltage adapter. Center +

1/4 inch output jack is the units output. The size of the unit is 6 x 3 3/4 x 2 inches. The unit has rubber feet under it to keep the unit in place."
