AF PLAYER (Audio File Player)
AF PLAYER is a simple single audio file player with variable fade in / out times and a built-in mixer with output limiter. We designed AF PLAYER for anyone who likes to perform, jam or practice with pre-recorded backing tracks and prefers to do everything in Voltage Modular like we do!
To use AF PLAYER as a mixer, connect your instrument module chain to the stereo IN jacks. Your instrument outputs will be mixed with the player and sent to the OUT jacks. Note that you don’t have to connect anything to the IN jacks if you prefer a different approach.
The LOAD FILE button opens a system file browser for you to navigate to an audio file. Currently supported formats are OGG, MP3, WAV and AIFF. Once a file is loaded, its name will be displayed on the button and the full path will be displayed as tooltip / hover text. If there is a problem loading the file an ERROR message will be displayed on the button.
A playhead slider above the transport buttons indicates the current playback position of the file. Moving the slider will change the playback position.
The PLAY button starts and stops playback and the volume will increase or decrease over the time set in the FADE IN / OUT section.
You can also toggle playback with an external CV trigger (+1V or more) via the TRIG PLAY input jack. The adjacent LED will flash when a trigger is received.
The LOOP button enables looping so the file will play continuously.
The RWD button rewinds the playhead back to the start of the file.
The FADE IN / OUT section allows you to vary the fade in and out time in the range of 10 ms to 10 seconds. Longer fade times are useful if your file is an ambient background type texture. Or set a shorter fade out time so playback doesn’t stop abruptly. A pair of status LEDs will light green to the left during fade in, and red to the right during fade out.
The MIXER section can be used to get the right balance between your input (IN) and the file playback (FILE) levels and also to adjust the overall output. Each knob has a range of -48dB to +12dB. If the IN or OUT levels clip, the LEDs above the level meters will light up. Please note that the OUT levels are auto-limited to -0.3dB.
What about play lists? We haven’t added support for saveable playlists as we’re assuming that in most cases for a typical track or performance, you’d have a different Voltage Modular preset setup for each track - each with its own specific modules, effects chains and an AF PLAYER with the backing track for that particular song or whatever. However, if there’s enough interest in play list support or any other features, please let us know!
We hope you find AF PLAYER useful!
