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.

TD-Linux: Re: the tweet you just made, why would you have 700v of common mode voltage? That seems like a pretty bad CMRR unless I'm missing something
<TD-Linux>
cr1901_modern, common mode vs ground
<TD-Linux>
the waveform itself is 1kv peak to peak
<TD-Linux>
which only barely fits in the 1400v limit of the diff probe
<TD-Linux>
but it's not centered
<TD-Linux>
cr1901_modern, actually because the limit is common mode + differential so absolute limit is +/-1400V. I should be able to use the probe without exploding
<TD-Linux>
its capacitance is still going to be a problem though
<cr1901_modern>

Oh, hrm
<andlabs>
well the SID works now :D but the Sequential interface doesn't seem to be detected by the cynthCart...
<andlabs>
I'm probably using the min Xpander wrong
<andlabs>
I'll need to write a sample program (like one of the type-in programs in the Sequential manual) to test that part
<cr1901_modern>
oh very nice :D

<andlabs>
so I now bought a second SID chip
<andlabs>
I have a SID2SID parts kit coming in
<andlabs>
but when I went to buy the SID2SID board itself
<andlabs>
ERROR!
<andlabs>
Submitted price xxx differs from correct price: yyy
<andlabs>
oops
<andlabs>
sid2sid update: it was a glitch in the country selection box
<andlabs>
whee bought the sid2sid board; once all three parts come I can possibly set up a six-channel c64 musi cmaking setup — also I bought a mssiah cartridge because why not
<andlabs>
oh right context: mssiah and sid2sid are made by the same people
