Functions <go back to table of contents>
This new version of JamMan/MutMax software supports a lot of new "Functions" along with the origional ones. The mode is active when the LED is flashing.
 
# Name Description
1. Layer In the Layer mode, new audio is added to the current audio held in memory.
2. Broken Reverse Reverse playback is still broken but I left what little I got working, in the code for people to mess around with. When you tap a second time to play it forward again, the loop is cleared.
3. Replace In the Replace mode, the previous contents of the audio memory is replaced (recorded over) with the current input to the system. The output of the old audio is muted.
4. Mute This mutes the output of the active channel. The actual audio is retained in memory.
5. Fade (not implemented) In this mode the "Level" of the channel is slowly reduced untill the channel is effectively muted. Currently, you must manually reset the "Level" of the channel.
6. Destructive Fade This function reduces the signal level of the audio in memory. This is useful for when a loop has gotten fairly busy and you want to add new content. The old audio is effectively pushed down in level.
7. Active Channel Trigger When the "Num Repeats" for a particular Channel is set to something other than 0, the channel needs to be triggered in order to play. The trigger enqueus a start of the channel's playback. At the next loop boundry, the loop starts playing (the number of times indicated by the "Num repeats" parameter.
8. All Channel Trigger This enqueues the start of all the channels playback. (each channel has a "play count". This clears them all).
9. Echo/Delay This puts the channel into the Echo/Delay mode. This is very cool. You can set the "Feedback" parameter for feedback of the delay and the "Echo Divide" parameter allows the loop size to be divided down. If the "Num Beats" is set for 8, and the "Echo Divide" is set for 8, an echo is produced every beat. "Echo Divide" set for 2 would produce an echo every measure. Note that when you first enable the Echo/Delay mode, you hear the current contents of the audio memory play back. If the feedback is turned up, it will continue to loop.
10. Stop Start This stops and restarts the current loop.
11. Reset This is the same as pressing and holding the RESET/BYPASS button.
