Mode 74
2 Sprite, 4 inputs each, 8 outs pulse Low after file ends, re-start delay on input 1, w/ interrupt
Mode 74 is the same as Mode 73 but with interrupts.
Any file playing may be interrupted to start a new file when a new input trigger occurs.
There is a brief delay before a new trigger is allowed if a prior triggered file just began.
Input 1 still has the re-start delay active.
Mode 81
1 Sprite, 9 inputs, 8 outputs, files queued, play in the order of inputs triggered, no interrupt
Mode 81 controls one Sprite on Port 1.
It will store trigger inputs in a queue buffer and play them in the order received.
The first trigger input will play immediately.
It has 9 trigger inputs.
When power is applied the file named 000 will loop circular continuously until a trigger event.
Inputs 1 to 9 will trigger when grounded / connected to input 0.
Inputs 1 to 8 will cause the corresponding file named 001 to 008 to be stored in a queue buffer.
As files are stored, they are played in the order received.
The buffer will only hold 8 triggers.
If an input trigger is already in the buffer, it can't be stored again and will be ignored.
If a file number is currently playing, it can't be stored in the buffer until it has finished.
Mode 21 is No Interrupt
While a file 1 to 8 is playing, it will play to the end.
While the file 1 to 8 is playing, the corresponding sinking output will be active.
Input 9 will interrupt all files, return to the 000 looping file and turn off sinking outputs.
Mode 82
1 Sprite, 9 inputs, 8 output, files queued, play in the order of inputs triggered, delayed trigger
Mode 82 is exactly the same as Mode 81, except triggers are delayed on file 000.
If file 000 is playing, files stored in the queue buffer will not begin until file 000 ends.
Read FAQ about Delayed Trigger at end of manual.
Mode 81 or 82 could be used for audio announcements where each of the 8 inputs could play a
message. Messages will play in the order that the inputs were triggered. Add a second or two of
silence to the start and end of each message for best results.
Mode 81 or 82 could be used as an audio or video puzzle, where the user must activate the
inputs in a certain order to play the content in the correct order to solve.
