Landscape Soundwich Audio Trigger and Processing Device

Soundwich allows you to tap, click, shake, and amplify, as well as route audio and excite effects. Explore the sounds of tact switches, hardware and PCB material. Two piezo disks are directly mounted to the undersides of the top and bottom surfaces creating a direct connection to the sounds of clickable tact switches. When you shake the Soundwich, you’ll hear the sound of six washers sliding along machine screws and colliding against the two piezo pickups. Routing audio or CV through this passive device provides a fast and tactile handheld momentary on.

What it can do

• Tap fingers on Soundwich or surrounding hard surfaces to create percussive sounds
• A shaker, with momentary or constant out, using internal washers
• Amplify internal click sounds
• Input or output audio
• Constant output from dual piezos
• Momentary output when disks are depressed in center point, or through 8 different filter amounts when depressing disks along edges
• Rhythmically excite resonators and effects
• Lo-fi vocal mic when pressed against the lips
• A very quiet lo-fi speaker
• Tactile momentary on switch when routing audio through it
• Momentary on with low-pass filtering and volume attenuation
• Momentary on plus attenuation of modular signals
• Trigger, with clicks or shakes, some synthesizer modules without needing an extra boost to modular levels

How to use it

SOLDER: For the DIY kit, soldering of surface mount parts is required. Approximate build time is 30 minutes to 1 hour depending on past experience. Follow the instructions here.

INS/OUTS: The two 3.5mm jacks can be used as either ins or outs. One is a momentary out (to the right of “Landscape”) and one is always on (to the left of “Landscape”). The momentary output allows you to hear only the depressed click sound of the tact switches while the always on output allows you to hear both the depress and release of the tact switches amplified by the two piezos. Routing audio or CV through the Soundwich provides a fast and tactile handheld momentary on device.

SHAKE: When you shake the Soundwich you’ll hear the sound of six washers sliding along machine screws and colliding against the two piezo pickups. 

CLICK: When compressing the disks with your hands you’ll hear the clicking of the 8 tact switches transferring through the PCBs and into the piezo pickups. 

TAP: When placed on a hard surface each side of Soundwich can create different rhythm sounds when tapped.

FILTER/ATTENUATE: Using momentary out will only allow sound to escape when disks are compressed. Compression along the edges will provide different filtering amounts depending on where you press. The 7 stacked lines indicate greatest amount of filtering/attenuation with less filtering as your travel counterclockwise till there is nearly zero. This filtering and attenuation can be used for audio or cv.
