Was starting to build the thing from the other thread on fluid.bufnndsvd~ and I noticed that it doesn’t take @startframe and @numframes messages.
So a feature request post here on being able to do that, particularly since fluid.bufnmf~ can take those messages and they would often be used together.
For now I can fluid.bufcompose~ the section I need ahead of time, but given that this will be in a looper-y context, there will be overdubbing or other kinds of manipulations, which would require a fluid.bufcompose~ per-time that something changes.
