ChanServ 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://freenode.irclog.whitequark.org/~h~yamahasynths
<andlabs> [21:32:27] <+andlabs>update: I went with the CBX-K1
<andlabs> [21:33:14] <+andlabs>it's just the unit on its own so no power cord (but I got it specifically because it has both a MIDI OUT port and runs on batteries and there's lots on ebay) or manual (but yamaha still offers the PDF)
<andlabs> [21:33:27] <+andlabs>and it also appears to need some retrobrite, so that'll be fun if I choose to risk it
<andlabs> also it's just the K1, not the K1XG, so it has no synth, but still
<andlabs> heading home brb

<andlabs> I also bought another m-audio midisport uno, just in case

<andlabs> what's the circle with an upward arrow in the middle?
<cr1901_modern> Beta typically means modulation index IIRC
<cr1901_modern> so it's a multiplier for the gain
<andlabs> ok

<cr1901_modern> andlabs: I need to work on this more, but the delta-theta-m is the Beta in that diagram you showed: https://gist.github.com/cr1901/e9fd2a75b2f07b67c46e0c0128c58ea9
<andlabs> oh, this is neat
<andlabs> but I was asking about the symbol =P
<andlabs> what a circle with the arrow means
<cr1901_modern> Oh it reminds me of a variable circuit element
<cr1901_modern> you'll see the arrow on potentiometer schematic symbol
<ej5> you mean ϕ?
<cr1901_modern> yes, that
<cr1901_modern> lemme guess
<cr1901_modern> that's phi and not theta
<ej5> there are two kinds of college students who know all the greek letters
<cr1901_modern> frat members
<ej5> and
<cr1901_modern> EEs?
<ej5> engineers lol yes
<ej5> technically the math and physics people do too
nonlinear has quit [Quit: The Lounge - https://thelounge.github.io]
<cr1901_modern> well the piece of paper claims I fall under the second category
nonlinear has joined ##yamahasynths
<cr1901_modern> and I'd never join a frat :P
<cr1901_modern> ej5: (Fun fact: I'm not actually allowed to call myself a professional engineer)
<ej5> me either
<ej5> never did the PE exam

<ej5> also that's a really interesting/weird way to get formulas into markdown
<cr1901_modern> yup, neither did I... and when I learned you have to take it a second time 5 years later, I lost interest
<cr1901_modern> Oh yea, I'm abusing a webservice lol
<ej5> reminds me, you ever find a good way to preview markdown?
<cr1901_modern> ctrl+shift+M in Atom :P
<cr1901_modern> If you mean on GH gists, no
<ej5> ah, i'm using vim which does syntax highlight but no preview
<ej5> i'm writing your sb dsp spec in markdown so...
<cr1901_modern> dillinger.io
<andlabs> what about linguists
<andlabs> =P
<cr1901_modern> linguists?
<andlabs> [18:13:19] <ej5>you mean ϕ?
<cr1901_modern> And while I'm able to exit vim, about 30% of the time I end up using ctrl+Z, so I'm not the person to ask.
<andlabs> in the middle
<andlabs> [18:19:17] <cr1901_modern>linguists?
<andlabs> in re [18:13:56] <ej5>there are two kinds of college students who know all the greek letters
<ej5> that's just a little gain block
<andlabs> oh
<ej5> multiply by constant
<cr1901_modern> I thought the arrow meant variable gain
<cr1901_modern> like a potentiometer or varicap
<ej5> it is variable, it's whatever gain is specified by beta
<cr1901_modern> oh shit, varicap == varactor, which does NOT have an arrow
<cr1901_modern> TIL
<cr1901_modern> ej5: Anyways, I mostly know markdown by memory, including stuff like tables, so I tend to write most of it before previewing it in Atom. But Dillinger.io should be just fine (and can handle GFM)
<ej5> cool
<superctr_> if you use linux, okular is pretty nice
<superctr_> it auto reloads files
<superctr_> it's a viewer, not an editor, so you just keep editing markdown in your editor ,and every time you save, it is automatically reloaded
<superctr_> works for latex too (if you run pdflatex after saving or have your editor do that)
<andlabs> okular supports markdown but not dvi?
<andlabs> something seems wrong with that picture
<superctr_> it does handle dvi
<superctr_> pdf just works better
<andlabs> well then
