droning sounds, or possibly when using Mopho to process external audio, 
turn the VCA Level up. 
Push It Mode: Normal, Toggle, Audio In—When set to Normal, Push It responds 
like a key: press it and a note plays, release it and the note ends. But when set to 
Toggle, Push It
 turns the note on with one press and off with a second press. 
This is handy for making a note drone or for latching a gated sequence on. 
Somewhat related, the Audio In setting will generate a gate from Audio In. 
When the audio signal gets above a certain fixed level, the gate will go on. 
When it drops below that level, the gate will go off. 
Push It Note: C0…C10—Sets the note that plays when Push It is pressed. 
Push It Velocity: 0…127—Sets the MIDI note-on velocity. 
Unison On/Off—Why does a monophonic synthesizer need a Unison switch? 
Because it might be poly chained to another DSI synth, the Tetra being the 
obvious choice—five voices of analog power, in a very small footprint! 
Unison Mode—Sets how voices are allocated and tuned when unison is on.
