Bugs and feature requests



Creates MIDI events based on LV2 time position events (bars and beats), e.g. to drive a drum machine. Bars and beats can be disabled/enabled separately.


Synthesizes click tracks based on LV2 time position events (bars and beats). Bars and beats can be disabled/enabled separately.


Loops arbitrary LV2 atom events on a ping-pong buffer. E.g. loops MIDI, OSC or anything else that can be packed into LV2 atoms with sample accuracy. Needs to be driven by LV2 time position events.


Creates LV2 time position events from scratch to drive other plugins.


Quantizes incoming events to whole beats.


Subdivide or multiply incoming time signals by whole fractions, e.g. to speed up time x2, x3, … or slow it down to x1/2, x1/3, …


Break out transport events to parameters, e.g. to get BPM, etc. and automate other plugins with those values.


Record/Playback of arbitrary LV2 atoms to/from memory. Record all incoming atom messages with sample accuracy and play them back later from memory. Stored atom event data is part of the plugin state and thus preserved across instantiations.
