Just a quick one to show a couple of new features. I’ve recently added a couple of commands to let you write to the two hardware sweep registers on the NES. It’s a bit of an experimental and esoteric feature but it does let you create some odd sounds. I’ve only scratched the surface here in this video but it gives you a flavour of what you could do.

I’ve got the effect on voice B to make the synthy kick drum and then on voice A a few thrown-together notes (which you can hear before I turn the effect on about half-way in). With the pattern looping I’m just tweaking a few settings and muting/unmuting tracks for effect. There’s nothing at all on voice C.

Ignore the timing of the TB303 sample on the DPCM channel. Because of the tempo works on NTRQ the other channels don’t always stay in frame-accurate sync with the long sample. I could fix it by chopping the sample into single notes or something but that wasn’t the point of doing the video, so…. :)
