I actually published my method to gather the combined waveform data for each of our SIDs more than ten years ago:

Our new research is more advanced, but its not ready for publication.

In the mean time, we can reasonably emulate the combined waveforms of the SID (which are really an odd mixture of bits in the analog world) by indexing a pre-recorded table ...

Thanks for sharing, David. It will be interesting to learn how you folks have improved upon your methods from 2010.

I just bought most of the plogue stuff (didn't get bifule, which I can't really even tell what that is, and didn't get chipsynth FM because MD seems better).

One of the best parts of chipsynth MD is the vgm player where you can copy patches from games directly to the synth. This is PERFECT. Is there more info anywhere about future chipsynths? I heard there is an upcoming NES one and an upcoming SNES one but don't know the details about their functionality.

What I'm really looking for is the ability to import NSF files into a NES synth and copy patches to analyze them. I think you can do this in famitracker but I really just want a vst to do it, not a tracker.

Thanks!
The currently announced ones are
SFC (Super FamiCom) or SNES (next one)
FC (FamiCom) or NES
C64

We did hint on another, but there are like 5 more in the long term.

Can’t wait for the C64!

Does anyone know if there's a way to do a very fine adjustment of pitch (like in cents) in the wave sequencer in chipsounds?

In the CC list there's a pitch adjustment CC but it has a 2octave range. I'm trying to remake the chorused square wave patch from the intro to legend of Zelda but it's not possible to get it exactly perfect unless there's either a fine pitch adjustment in the wave sequencer, or there was a "one shot" mode when using the user definable lfo pattern.

The alternative would be the to set the Pitch Modulation's LFO Type to user1 or user2 and draw the exact (or similar) pattern into USER LFO 1 or 2 (I vividly recall what you mean but haven't analysed the pattern exaclty)

Except then it would repeat, which is why I'd need a "one shot" mode for the LFO. It's strange that fine pitch adjustment isn't programmable in the wave sequencer, since this is very common in old games.

You are indeed right.
Design issue in this product. We thought PitchLFO+PItchEG would be enough for cents detune automation. This is the first time that I recall someone brings this up though.

I know its not going to help you, but the only thing I can say is that chipsynth FC will not have that limitation. Sorry

Is it planned to implement import of game patches via .vgm for all of the console based emulations? Specifically, C64 and NES

C64 and NES sound formats (PSID/RSID/NSF/NSFE) do not contain 'patches' in the typical FM sense but actual 8bit 6502 processor instructions that tell the system how to play full songs and how to modulate the few parameters exposed by those chips in real time. So one must study how parameter automation is applied by those routines and reconstruct modulation tables from that. Its not trivial, but definitely an area of great interest of mine. Can't really disclose more for now.

Getting closer! I could buy it and I received my license key* but there isn't a download yet that I can find.

I can be patient.

Yeah sorry about this. Looking at the cause now.

What's up at Plogue?
