While waiting

While I wait for my AVR programmer, I have been working on the VA synth. This is what I have added this weekend:

LFO: Added the delay to the LFO. So LFO is now complete.
HPF: I played around with different filters, and I did not see the point. Will probably install a Juno106 clone VST and play around to figure out what should I be expecting from the HPF, cause as far as I tested it did not add much (or, considering it is a filter, did not remove much).
LPF: I added a new filter and that sounds A LOT better. Will record a sample soon. Also LFO now controls the filter. Still missing keyboard tracking.
AntiAlias: Added a better antialias downsampling filter.
NOISE: Improved the CPU performance of the NOISE section. I was just calling rand() before and that does not seem to be the most optimal. I added a random number generation technique which only required a multiplication and an addition.

One thing I want to start looking into is adding a way to store/load presets. I think I will use an XML file for that, but still not sure.
