Hey all 
This update introduces a new audio effect: stutter is a beat repeat effect great for adding variation to percussion or repeating pitched notes. With control over the repeat pitch and volume various effects can be created: repeats fading in or out and the pitch going up/down over time. Of course these parameters can also be modulated.
The compressor has been rewritten and now uses a lot less CPU. While rewriting a lot of performance was gained by replacing the ratio parameter with the amount parameter. Setting amount to 0% corresponds to a ratio of 1:1 (no compression) and setting amount to 100% is the same as a ratio of inf:1 (maximum compression).
Highlights:
- Added stutter audio effect:
- clock mult set repeat rate and length in relation to the BPM.
- chance sets the chance of starting a repeat when triggered.
- rate sets the playback rate/pitch of the repeats.
- volume sets the volume of the repeats in relation to the incoming signal.
- rate delta and vol. delta set the change in repeat playback rate and volume applied after each repeat.
- Improved compressor performance:
- Lowered CPU usage from 6.4% to 1.8%
- The amount of gain reduction applied to signals above the threshold is now set with amount instead of ratio.
- Modulators assigned to external sound engine parameters can now be triggered.
- Added envelope curve parameters to AD env:
- Hold and turn attack to change the att. curve.
- Hold and turn decay to change the dec. curve.
Other changes and bugfixes:
- Fixed a crash when removing an audio effect with one or more modulators assigned.
- Fixed the random pan positions in stereo sometimes getting stuck at one location.
Here is the new firmware: polypulse-firmware-0.3.8.zip (1.0 MB)
See here how to update your PolyPulse. Note that the file manager only recognizes *.zip files whose name starts with polypulse-firmware- as firmware updates.
Enjoy!
