Re: How do you set a breakpoint?
Is it just the F9 key that is not working? (Haven't tried that myself yet) Just wanted to mention there is a register in the memory map which disables emulator key shortcuts: $9FB7. Just an idea if that flag might be set, although admkttedly it's unlikely to happen on accident https://github.com/x16...

Re: Concerto Dev Log
I am currently working on a beta release of Concerto Multitrack. The coding is done, except for bugfixes. The focus now is on the content that comes with the software: Most importantly, the user manual, but also the presets and demo songs. Although I am sure that experienced musicians will immediate...

Re: Noise pitch is different in emulator vs hardware?
Let's hope it is as easy as you suggest.

Re: Noise pitch is different in emulator vs hardware?
Thank you! Much appreciated. If for some reason, the down-clocking of the LFSR is too difficult to implement, here's another way of decorrelating subsequent iterations: We could cut the sequence of 65535 values short somehow, which makes the total number of samples less similar to a multiple of 512....

Re: Noise pitch is different in emulator vs hardware?
Thank you! I am not yet familiar with Verilog, so I'll have to take your word for it at the moment. I do not know how the sequence of 65535 values in the LFSR are turned into audio samples, but let's assume they do. That means we have a sequence of 65535 unique (semi-random) samples which we are bur...

Re: Noise pitch is different in emulator vs hardware?
Do you know how many bits the LFSR is? And is the VERA running at 8 Mhz or does it have its own clock?
Your idea sounds plausible to me. Maybe it can be verified with some clever experiments.

Re: Problems with YM sound effects on real hardware (works in emulators)
This is what is working reliably for me (16 cycles if I count similarly to you). With one less NOP, I got occasional FM glitches on real HW. Not 100% certain but I think glitches occurred mostly during patch changes. sta YM_reg nop ; 2 cycles each nop nop nop nop nop sty YM_data ; 4 cycles
