The LFO rate was not correctly syncronising to tempo
This has been rectifited, to utalise the TempoSyncKnob as intended, returning a period,
instead of a frequency. The knob now reports the correct values in the GUI.
Flanger LFO maximum period incressed to 60 seconds
The previous delay code was incorrectly not utalising the whole buffer, causing glitches when
incressing the delay time, due to outputting incorrect data, This was apparent when using the
lfo in the Delay and Flanger plugins.
This has been rectified. The read index is now offset from the write index. and the complete buffer is used in a circular fashon.
Flanger - resolved issue where the lfo could create negative delay lengths
