I've been having fun with some of the more exotic combinations of sound generators in Furnace Tracker. Turns out that you have to define an instrument for samples in order to use them. I'm used to trackers that are sample-based just letting you go by sample index, but that's not the case here, and I took a while to figure this out because it's not in the documentation
I'm in the middle of progress so nothing to show for it yet, but hopefully soon
I can upload the tracker files on gdrive if people are interested
And downloaded sidwizplus to get an oscilloscope video of it It took me a while to figure out how the YM2151's LFO works relative to the YM2612, and I also took a long time to realize that the base frequency of the chip appears to be higher than the 2612 (i.e., what furnace calls 'c-1' for the 2151 is an octave higher than what c-1 would be for the 2612). What I assumed would be a simple change required a fair bit of futzing around to get to a point I was comfortable with -- the 2612 LFO and lower base frequency rate are key parts of how I make compelling guitar-like work on the 2612. Ultimately I manged to get something I'm pretty satisfied with, though.
And if you want more oscilloscope fun, here's one for the song in the previous post:
