cr1901 changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic. Channel logs: https://libera.irclog.whitequark.org/~h~yamahasynths
<cr1901> Foone: Nope, windows-imager doesn't list the drive names, I was misremembering. But it's still a cool program: https://github.com/marler8997/windows-imager
<NiGHTS> GitHub - marler8997/windows-imager: Write an image to a disk on windows
<cr1901> I added crappy read support that probably only correctly works on floppy disks: https://github.com/marler8997/windows-imager/pull/3
<NiGHTS> Add disk reading functionality. by cr1901 · Pull Request #3 · marler8997/windows-imager · GitHub
<cr1901> B/c I don't read the MBR, bootsector, or "whatever EFI does" to get the actual used disk space"; I just "read the whole damn disk"
<cr1901> s/bootsector/Volume Boot Record/

<andlabs> does anyone know of any DX21/DX27/DX100 sample MIDI files
<andlabs> of songs
<andlabs> yes I know that would limit you to one voice but
<andlabs> while shoving General MIDI into it is amusing it's not shown to the full potential =P
<andlabs> anything not in IvoryEbony (the default voice) is either too hgih octave or not rich enough

<NiGHTS> Pietro Gagliardi sur Twitter : "does anyone know how to use the cassette device in a MAME driver or to decode a cassette circuit into the set of parameters used to encode the only thing I know about this is the circuit diagram and that it's some 1200 baud thing"
<andlabs> DX100 emulation almost done whee
<ZrX-NoMs> Firmware would be usually where you'd look into the data format.
<ZrX-NoMs> Tho tapes are usually pretty simple.
<andlabs> firmware gets the final digital data
<andlabs> I think?
<andlabs> it's not connected to an ADC
<andlabs> I mean the data storage, not the actual system-specific data
<andlabs> is it KCS or something else? and if so what are the parameters? and how do I feed that into the fromula ((m_cassette->input() * scale_factor) comparison_operator threshold_value ? 1 : 0
<andlabs> and/or reverse engineer the circuit to produce those values
<andlabs> it's not simple RC circuitry
<andlabs> though I see things that look like RC embedded within
<andlabs> but then there are resistors that are parallel with ground and capacitors that aren't and I don't know
<andlabs> P66 is the save/record and P67 is the load/play and the vertical line off the top is a tap to headphones which I assume ar for monitoring loads
<ZrX-NoMs> That circuit most likely just filters through a certain frequency signal and the opamp makes clean squarewave.
<ZrX-NoMs> Ah, a synth that uses tape as storage.
<ZrX-NoMs> Recently saw a Philips PMC 100.
<ZrX-NoMs> Hm, now I want a DX100 tape dump.
