Sorry I ve just uploaded the schematic now a long with an audio sample, there are a few alterations I would like to make, firstly I would like to separate the LFO from the circuit so sidechaining it is optional and also to have a pot controlling the cutoff frequency. As you can hear on the audio sample when the filter sweeps into the lower frequencies it often clips I had assumed this was because there was a set resonance which is why I was looking for a way to control it with a pot, any suggestions as to avoid this clipping sound would be much appreciated.
Thanks Stu
