• Stereo line out - Headphones, powered speakers or even wire up one of our

amplifiers to make loud sounds. We also have a version with built-in stereo

speaker amplifier

• Five different trigger effects - by changing the name of the files, you can

create five different types of triggers which will cover a large range of projects

without any programming

What do we mean by trigger effects? Well, depending on your project you may need

to have audio play in different ways. We thought of the five most common needs

and built it into the Sound Board so you just rename the file to get the effect you

want. See the product tutorial for more details

1. Basic Trigger - name the file Tnn.WAV or Tnn.OGG to have the audio file play

when the matching trigger pin nn is connected to ground momentarily

2. Hold Looping Trigger - name the file TnnHOLDL.WAV or .OGG to have the

audio play only when the trigger pin is held low, it will loop until the pin is

released

3. Latching Loop Trigger - name the file TnnLATCH.WAV or .OGG to have the

audio start playing when the button is pressed momentarily, and repeats until

the button is pressed again

4. Play Next Trigger - have up to 10 files play one after the other by naming

them TnnNEXT0.WAV thru TnnNEXT9.OGG. Will start with #0 and each one on

every momentary button press until it gets through all of them, then go back

to #0

5. Play Random Trigger - just like the Play Next trigger, but will play up to 10

files in random order (TnnRAND0.OGG thru TnnRAND9.OGG) every time the

button is pressed momentarily

The sound board is designed to be simple: it does not have polyphonic ability, can't

play MP3's (MP3 is patented and costs $ to license, so this board uses the similar

but not-patented OGG format, there's tons of free converters that will turn an MP3

into OGG), isn't reprogrammable or scriptable, and you can't have any other kind of

trigger type. However, there's a good chance the project you want to make will

work great.

We designed this board specifically for people who wanted to make props,

costumes, toys, and other small portable projects. Check out the tutorial for all the

powering options, you can power from 3-5VDC so a 3xAAA battery pack or a LiPoly

battery will work well. You can even use our LiPoly backpack to fit on top for an all-

in-one rechargeable effects board
