	Hi All, I'm working on a piece right now and it seems to me that the pluck opcode yields quite a dc offset. I tried adding a dcblock2 to it but it didn't seem to help, but dcblock seems to have done the job. Could someone explain the differences and when dcblock2 might be used over dcblock?

	In my experience, dcblock2 blocks more than dcblock. I am surprised it did not work for you.

	Hi Victor, I've posted a screenshot of the results in Audacity here: http://kunstmusik.com/dcblocktest.png and have attached a test CSD file. (Generated with blue so the CSD may be a little hard to read) I made three copies of the instrument, one with straight out, another with dcblock, and the third with dcblock2. The screenshot shows the first and 3rd renders with really bad dc offset, while the second shows little offset (using dcblock). I placed the dcblocking at the end of the chain before output for the instruments. I am wondering if there is something I need to do with dcblock2 in terms of settings or if it does not work well in this context but perhaps better in others?

	Looks like dcblock2 is broken. It's not cutting any DC. I'll need to look at it.
