Running Pulsar on my PAL NES, it is something like a tone and a third flat (or thereabouts), like totally out of tune, which really sucks cause I make my music with a guitar too! Could it maybe be that it's calibrated for NTSC consoles, and is running at a slower rate on my PAL console (and therefore producing lower tones)? I noticed for NTRQ there is a PAL and NTSC version, whereas for Pulsar there's just one version.
I emailed Neil a while ago but haven't had a reply, so I thought I'd maybe put it to you guys! I'm coming at this from LSDJ, so Pulsar is super intuitive for me and easy to use, whereas NTRQ terrifies me. But if there's no way to get Pulsar playing in tune with me (detuning my guitar would be awkward and also mean I couldn't switch between NES and Game Boy songs easily) then looks like I might have to learn to use it!
